Replace a car battery the right way? (Professionals recommend)

Steps to changing a car battery

  1. Remove cables from battery terminals.
  2. Remove the screws or fasteners holding the battery in place; then Remove the Battery.
  3. Inspect the tray the old battery was resting on.
  4. Position your new car battery on the tray.
  5. Replace the screws/fasteners to the new battery to secure it in place.

Do you connect positive or negative first when installing a battery?

When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” When you are replacing your car battery, It isn’t always easy to remember the order in which to disconnect and reconnect the terminals.

What happens if you remove the positive terminal first?

If positive terminal is removed first then chances of a spark are more if this terminal touches the body through the metal spanner or wrench you are opening with is grounded accidentally and may end in flames because lot of combustible material is around. And chances of this accidental touch are very high.

Why do you disconnect the negative terminal first?

The reason they say to remove the negative first is because it is safer for you. The negative cable in all modern cars is attached to the chassis of the car. SO when you put your wrench on the negative post to loosen it, and the wrench hits the chassis, nothing happens.

Do you need to reset car after changing battery?

Yes. You will need to reset your settings. Usually the dealer can do it free of charge but no promises. If you take a battery off and put a new one on, if there was anything hooked up the the battery, i.e. the hose you are speaking of, reinstall it.

Why do you connect the positive terminal first?

Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.

Do you hook up red or black first?

Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won’t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.

Is it OK to just disconnect the positive terminal?

You can disconnect whichever terminal you want, or even both, it won’t discharge. Whichever one you choose results in an open circuit so no current can possibly flow.

How are you going to determine if one of the terminal is positive?

Fortunately, most batteries also have a plus (+) and minus (-) sign stamped into the case. As you might guess, the plus sign indicates the positive battery terminal, while the minus sign indicates the negative battery terminal. Most batteries also have a positive and negative sign stamped into the case.

Is it OK to just disconnect the negative terminal?

Disconnecting the negative (chassis lead) will protect the electrical side of the battery. Removing the battery and storing it inside will protect the physical battery.

Will car battery drain if negative cable disconnected?

Be safe: always disconnect negative first. Disconnected either terminal will prevent drain, as stated already. A battery tender is another safe way to maintain the battery.

Which battery terminal must be disconnected first and why?

You should always remove the negative battery terminal first, to reduce the risk of sparks which can make the car battery explode. Once the negative terminal has been located, use the wrench to loosen the nut that holds the terminal.

How to Replace a Battery

Let’s get this done! Disposing of the old battery and replacing it with a new one is a rather simple procedure. In terms of special tools, it is not overly complicated, and it can be completed in a short period of time provided you have completed the essential preparatory tasks ahead of time.

Removing the Old Battery

  1. Remove the negative cable from the negative terminal (the one marked with a minus sign) on the circuit board. In some cases, a tool may be required to release the cable-free connection on the battery. Remove the positive cable from the positive terminal—the one marked with a plus sign—and set the cable aside. It is important to be careful while using a metal instrument, such as a wrench, because the metal should not come into touch with the terminal. To accomplish this, loosen the battery hold-down, connections, and/or fasteners that are holding the battery in place. Remove the battery by lifting it up. Get some aid if necessary because the battery might weigh more than 50 pounds when fully charged. Placing the battery in a safe location is recommended

Add the New Battery

  1. Clamps should be cleaned. Before you actually put the battery in, attempt to clean the clamps of any rust, dirt, or debris that may have accumulated. You may also clean the battery terminals to ensure that there is no build-up. Usually, all you need is a thin wire brush and some water or baking soda to complete the task. Fill up the holder with the fresh lithium-ion battery
  2. Secure the battery
  3. Reconnect the positive and negative terminals
  4. And secure the battery once more. Put the automobile through its paces. You may either try to rev the engine or simply switch on the electronics to see what happens. If everything works well, the battery is properly inserted, and you’re ready to leave, then you’ve succeeded.

  • Check the battery’s condition on a regular basis to ensure it is in good working order. After around five years of service, the majority of automobile batteries must be recharged or replaced. Make certain that you get the correct battery for your car. In order to obtain more thorough information, consult the owner’s handbook. Maintaining the batteries in an upright posture will help to prevent any electrolyte solution from leaking.

Is there any danger to changing a car battery?

Periodically check the battery to see how well it is performing; After approximately five years of service, the majority of automobile batteries must be refilled or completely replaced. Make certain that the battery you choose is appropriate for your vehicle’s specifications. For more specific information, refer to the owner’s handbook. To avoid any electrolyte solution leaking from the batteries, keep them in an upright posture.

How do I know which side to remove or connect first?

When it comes to deleting cords vs adding cables, it’s always the other way around.

In every case, the negative side is eliminated first. The good always takes precedence over the negative.

Do I have to replace the old battery?

Often, an old automobile battery may be recharged before it has to be replaced altogether. It is necessary to have a charger and a battery that can retain a charge in order to do this.

Will changing the battery affect the on-board computers?

However, certain systems may undergo a reset or memory loss despite the fact that it shouldn’t happen. If removing the battery results in a high-voltage energy surge, it is possible that damage will occur.

Life Hacks

Because you may not have access to the proper equipment or a buddy from whom you can borrow a wrench, we’ve created a list of our favorite hacks to make your life simpler while draining your bank account as little as possible.

  • As an alternative, if your battery is dead and you don’t have a replacement yet, or you can’t get to one, gently remove the battery’s top and put two aspirin tablets into it, as the active substance will generate enough of a chemical response to provide one last spark
  • Batteries are particularly vulnerable to the effects of cold weather. As a preventative measure before winter sets in, remove the battery terminals and clean them well before replacing them with petroleum jelly, which will guard against corrosion and aid in the maintenance of a spark during cold weather.

When To Replace Your Cars Battery

When it comes to determining how long a car battery will survive, there is no straightforward answer, but it is feasible to make some broad generalizations based on decades of industry knowledge and experience. To begin, we are aware that the life of a car battery is affected by three important factors: time, heat, and vibration (to name a few). Each of these will be examined in further detail. Time Car batteries, like people, mature with time and have a limited useful life expectancy. Even under optimal working circumstances, batteries progressively degrade until they can no longer produce enough power to start an engine.

  • Cars that are driven primarily on short excursions may not be able to recharge their batteries entirely, and batteries in cars that are parked for lengthy periods of time may naturally deplete.
  • HeatHeat helps to speed up the chemical reactions that batteries employ to create power, but it also accelerates the pace at which batteries degrade and degrade faster.
  • Batteries are also subjected to a tough underhood environment where temperatures can often approach 200 degrees Fahrenheit in extreme circumstances.
  • In addition to temperature, vibration is another important element in battery life, since it promotes physical disintegration of internal battery components.
  • Hold downs that are missing or are loose might cause a considerable reduction in battery life.
  • Under- or overcharging a battery on a regular basis causes its age.
  • Finally, even though a car battery can be recharged and put back into operation, allowing it to become fully dead would shorten its useful life significantly.

Another sign of a poor battery in older vehicles is faint incandescent headlights, which are particularly noticeable at idling.

In order to prevent getting stranded due to a battery problem, have the battery inspected at every oil change to ensure that the cable connections are clean and tight, and that the hold down hardware is in good condition.

In order to avoid an unexpected failure, the battery must be tested and determined to be in poor condition, at which time it should be replaced immediately.

Tips for Choosing a BatteryThere is no “one-size-fits-all” battery that is ideal for any automobile.

Correct battery installation can have a negative impact on your vehicle’s electrical system and could cause serious damage if the terminal placements produce a short circuit with other components in the vehicle’s electrical system.

Batteries come in a variety of shapes and sizes.

Despite the fact that the majority of automobiles on the road today are powered by conventional batteries, some models employ AGM batteries, which are highly spill resistant and better able to withstand repeated discharging and recharging, as is the case in vehicles equipped with engine stop-start systems to improve fuel economy.

  • Number of Members in a Group The group number, for example, Group 24, is an industry standard that specifies the physical size of the battery, its hold down arrangement, as well as the kind and placement of the battery’s terminals, among other things.
  • It will also enable for the appropriate reinstallation of the critical battery heat shield, if one is present on the battery.
  • In many circumstances, a conventional group number battery will fit with just little or no modifications, but it is important to pay close attention to the installation process to ensure that there are no complications.
  • In a small number of automobiles, the architecture of the vehicle makes a factory replacement battery the sole practical alternative for battery replacement.
  • Never be confused with “cranking amps,” which is a rating based on a simpler test that yields exaggerated results, since this is not the case.
  • Commonly, this rating is dependent on how long a battery can maintain a particular amount of electrical current, which is typically 20 amperes.
  • It is possible to use a higher-rated battery provided it is correctly installed, however this is typically not essential and may result in a reduced service life in warmer areas.
  • Keeping a battery on the shelf after it has already lost a significant amount of its useful life is not an ideal situation.
  • If there is a problem with the battery during that time period, quality batteries will provide a free replacement for three or more years.
  • Obtaining High-Quality Automotive Repair Aaa suggests that you prepare ahead of time for car servicing by locating an auto repair shop and mechanic you can rely on before you require their services.
  • Every Approved Auto Repair facility is subjected to frequent inspections and customer surveys by AAA to ensure that they are performing at a high level.

Auto repair reductions, a parts and labor guarantee that is extended for an additional 24 months/24,000 miles, and support from AAA in addressing repair-related difficulties are just a few of the particular perks that AAA members may enjoy.

How to Change a Car Battery

No matter how well you take care of your vehicle, car batteries will eventually wear out and need to be changed after a few years. As automobile owners, it’s simply another one of those things that needs to be done on a regular basis. Luckily, installing a new battery is a basic procedure, and one we’d suggest for all DIYers. Do it yourself in the garage on Saturday morning, and you’ll have confidence that your car will start on Monday morning — and every morning, even in the coldest temperatures — for the rest of the year.

Before you begin, make certain that you have selected the appropriate battery for your car.

Beginner’s level of ability New DIYers will benefit from completing this project.

  1. Learn how to change your battery. VideoWarning When working with batteries, always use gloves and eye protection to keep yourself safe. The use of a memory saver is also advised, although it is not mandatory. This step may be skipped, and you may find yourself having to reset your radio, clock, and probably a few other electrical devices after you’re through
  2. The location of your automobile battery may be found in the owner’s handbook for your vehicle. Many newer vehicles have limited space under the hood due to the design of the engine. Some batteries may be hidden in the trunk, beneath the floorboard, or even tucked down behind a wheel well, out of sight. Identify the positive and negative posts and the associated wires connecting to each. The positive post may be protected by a red plastic cover, and/or the wire that connects to it may be red as well. In addition, a “+” sign should be imprinted or written on the battery, adjacent to the positive post
  3. Remove the nut or bolt that attaches the negative terminal and cable to the negative battery post with a tool. Caution Make sure that no metal items come into contact with both battery posts at the same time, and that your wrench does not come into contact with both the positive terminal and the body or fender at the same time. Once the bolt or nut has been loosened, use the terminal puller to remove the cable and terminal from the negative battery post, which should be done first. Carry out the same procedure with the positive terminal. Using a clamp or retaining device, remove the battery from its mounting and lay the pieces and fasteners away to prevent them from being spilled or misplaced
  4. Carefully remove the battery from the case without jarring it too much (be prepared, it is slightly heavy). If the posts are situated on top of the battery rather than on the side, the battery carrying strap can be used
  5. Otherwise, it cannot be used. Check the terminals attached to the ends of the battery cables to make sure they’re clean and free of corrosion before using the batteries. If they aren’t, use the terminal-cleaning tool to disinfect them. There is a unique tool that goes over the post and another brush that fits within the clamp that may be purchased. In the event that this is not possible, a strong wire brush can be used. The cleaner your battery’s posts and clamps are, the better and more positive of a connection you’ll have with your battery. Position the battery such that the red, positive post corresponds to the placement of the positive terminal and cord. Replace the old battery with the new one. Then, using the clamp or retention mechanism that was previously removed, secure it. Discard the protective plastic covers that cover the battery posts and replace them with the anti-corrosion washers over them. Make sure to lubricate the battery posts and terminals thoroughly before connecting the positive terminal to the positive post for the very first time. The use of special anti-corrosion grease can help to prevent the accumulation of fluffy greenish-white corrosion deposits, which can actually prevent the battery from charging properly. Tighten the connector until it is snug by using the wrench to do so. After that, repeat the process for the negative post and terminal. Make an attempt to wriggle the battery. It will move if the clamp or retention mechanism is not tightened. You’ve completed the installation of a car battery! Feel good about yourself for a job well done, and drive with confidence, knowing that you will not be stuck due to a dead battery
  6. You may recycle your old battery by bringing it to your local Advance Auto Parts. It doesn’t matter if you bought a battery from Advance or not
  7. When you bring in a vehicle or light truck battery for recycling, you’ll receive a $10 shop gift card.

How to Change a Car Battery Like a Pro

  • Insulated work gloves, safety glasses, socket wrench set, cable clamps, car battery, lithium grease, and other supplies

BEFORE YOU BEGIN

Step back and think about the potential hazards of removing or reconnecting a car battery before you even contemplate taking the plunge and doing it yourself. Car batteries are extremely strong electrical devices that, if not handled with care, can cause considerable damage to the vehicle as well as severe injury to the DIYer performing the maintenance. You avoid danger, make sure to take the necessary safety precautions and to follow these procedures in the order that they are listed. IN CONNECTION WITH:12 Car Maintenance Mistakes That Shorten the Life of Your Vehicle

STEP 1: Find suitable parking and turn off the vehicle.

It’s generally a good idea to park your car on a level surface in an area that is somewhat private and secure, such as your garage, a level driveway, or even on the side of the road in front of your house, when doing vehicle maintenance or repairs. As soon as you’ve located an adequate location to work on the car, put it in park and turn the vehicle off. Make sure that the keys are not in the ignition to guarantee that no electricity is being sent to the battery. Also, bear in mind that when you remove the battery, the clock, radio, navigation system, and alarm settings will most likely be reset, so you will need to reset these auxiliary functions when the repair is completed to ensure that they function properly.

STEP 2: Put on safety gear and locate the battery.

Wearing protective eyewear and work gloves that are insulated against electricity can help you stay safe while performing this car repair. Make careful to take off any metal jewelry that might come into touch with the battery, such as a watch, ring, or bracelet, before starting the battery replacement. A short circuit between the negative and positive terminals of these things might result in the metal sparking, heating up, and perhaps melting on your flesh as a result. Severe burns are no laughing matter, and they will require medical attention; thus, prevent the problem totally by avoiding metal jewelry and accessories.

When it comes to automobile batteries, they are just a huge rectangular box with two electrical wires attached to metal terminals on the top of the battery.

If you have never seen one before, they are easy to recognize. Some modern cars can have a plastic cover over the battery, but you can remove it to have access to the battery connections.

STEP 3: Disconnect the negative cable.

When it comes to batteries, the negative battery terminal is typically black and may be marked with a minus (-) symbol to show that it is the negative terminal. Remove the plastic cover from the battery, if applicable, and look for the black negative terminal cable that connects to it. This cable must always be the first cable to be withdrawn and the last cable to be reconnected in order to reduce the possibility of completing a circuit between the two terminals and causing the battery to spark, short circuit, or melt down during the process.

Make sure the cable is kept away from metal objects such as the battery and positive cable by anchoring it to the engine bay with a cable clamp.

STEP 4: Disconnect the positive cable.

Locate the red positive cable once the negative cable has been safely secured and moved out of the way. In order to distinguish between the negative and positive wires, the terminal may be marked with a plus (+) symbol (see illustration). The positive cable should be pulled away from the positive terminal by removing the nut that is keeping it in place. Secure the cable to the engine compartment using a cable clamp, making sure that it does not come into touch with the battery, the negative cable, or anything else that is metallic in nature.

STEP 5: Remove the old battery.

It is common for the battery to be secured in place with multiple connectors in order to prevent it from shifting or moving while you are driving. To remove the battery from the battery bracket, use a socket wrench with an extension bar to loosen the connections and lift the battery out of the bracket. Keep in mind that a car battery can weigh more than 20 pounds, so you may want assistance lifting it out of the vehicle. It’s possible that you’ll be able to trade in your old battery at your local automobile parts store.

Please do not dispose of the old battery in the garbage.

STEP 6: Install the new battery.

Check to be that you are getting the right new batteries by writing down the model and year of your car, as well as the engine size, and taking this information to your local automotive parts supplier. If you purchase the incorrect battery, it may be either too large or too tiny to fit into the battery mount, making reinstallation difficult or impossible.

Placing the new battery in the battery mount is simple. Use your socket wrench to tighten the battery to the bracket, ensuring that it does not shift, tip, or otherwise move while you are operating your vehicle. OTHER RELATED:10 Things to Keep in Your Car That You Never Thought of

STEP 7: Connect the positive cable.

To avoid corrosion, oil the battery terminals with white lithium grease and then identify the red positive connection that you had previously connected to the engine compartment with a cable clamp. Lift up and down on the positive cable until it is snugly secured to the red positive terminal, which may be marked with a plus (+) symbol. Please take your time. Image courtesy of istockphoto.com Please double-check that you are connecting the proper cable to the appropriate connector. With a socket wrench, tighten the cable to the terminal and double-check that you’ve attached the correct cable to the terminal.

If you have a fuse in your car that is meant to safeguard your engine from this type of incident, it is best not to take any chances.

STEP 8: Connect the negative cable.

In order to avoid corrosion, oil the battery terminals with white lithium grease before locating the red positive cable that you had previously connected to the engine compartment with a cable clamp. Release the cable clamp and slip the positive cable onto the red positive terminal, which may be denoted by a plus (+) symbol on the terminal. Allow yourself some time to consider your options. Featured image from istockphoto.com Check to be that you are connecting the proper cable to the correct connector before proceeding.

It is possible to connect a vehicle battery in the wrong direction, which will cause electrical current to flow back through the automobile’s systems.

A large amount of damage can be done to the vehicle as a result of this charge.

STEP 9: Start the vehicle to test the repair.

Image courtesy of istockphoto.com Once you have successfully rejoined the wires in the proper sequence and orientation, you can replace the plastic cover that was previously placed over the battery, if one was there. Make a thorough cleanup of any tools that you used throughout the operation, then close the hood and get back into the car. The car should start up without a hitch, however you will most likely need to reset the clock, radio, navigation system, and alarm settings before driving away.

Take precautions when replacing a car battery to avoid harm.

Car batteries are very strong things that have the ability to cause serious injury or death to you and your car in a variety of ways, including burning, electrocution, corrosion, and overheating. Make sure that the battery is installed in the proper position and that you avoid working in the snow, sleet, or rain to help keep yourself safe from harm. It is also important to note that replacing a hybrid or electric car battery is not typically a do-it-yourself project due to the fact that these batteries have a potentially dangerously high voltage and can be difficult to access, remove, and reinstall due to the greater degree of complexity in the hybrid and electric vehicle designs.

If you own one of these environmentally friendly automobiles, it is recommended that you get the battery replaced by a skilled technician in order to avoid future difficulties with the automobile. In related news, here are the best car battery chargers.

A Car Battery Should Last About 6 Years, But That All Depends on How You Treat It

Even if you’re driving a gas-guzzler SUV, electricity is still required to operate a motor vehicle safely. Drivers no longer have to switch their engines over by hand, thanks to the advancements in electric battery technology. All of this may now be accomplished with the touch of a key or the push of a button. You have a passion for automobiles. We feel the same way. Let’s all become a little nerdy about them. The battery, however, continues to play an important part in all of your vehicle’s electric systems after it has been turned on.

Here’s a full debunking of those urban legends, as well as some cold, hard facts to take their places.

Battery Life (and Death)

Dave King is a musician and songwriter from the United Kingdom. Photographs courtesy of Getty Images A car battery should last around six years, but like with most automotive parts, how well you care for it will determine how long it will survive. Multiple discharge/recharge cycles degrade the life of any battery, and utilizing electronics in the car while the motor is turned off is the quickest way to a dead battery in any vehicle. In addition to maintaining its charge while the engine is running, batteries also serve as a power source for electronics when the engine is turned off.

  • Recall that leaving gadgets such as GPS units or mobile phones hooked into car chargers can also decrease the battery’s capacity.
  • When a battery is failing, it generally exhibits apparent indications that alert you that it is about to fail.
  • If your vehicle’s electronics, such as remote locks and interior lights, suddenly cease working, it might be due to a fading or dead battery.
  • Don’t just chuck it in the garbage since your local mobile mechanic or auto supply store may be able to recycle it on your behalf.

Weather Matters

Spencer Platt is a young man who aspires to be a writer. Photographs courtesy of Getty Images The temperature of the surrounding environment has a considerable influence on the battery’s life and performance. The majority of automobile batteries store their charge in a liquid electrolyte solution, which is impacted by hot or cold temperatures. While it takes extremely low temperatures to get a battery to freeze, cold diminishes the solution’s capacity to deliver the entire amount of power it contains (which is why it can be hard to start a car in winter).

Instead, invest in a battery warmer, which acts as a warm jacket for your battery, keeping it warm and dependable throughout the winter.

If this occurs, you may detect a rotten egg smell coming from the solution due to the sulfur content.

However, drinking tap water includes minerals and contaminants that can harm battery cells.

Keeping your automobile in a garage allows the battery to better withstand temperature variations, allowing it to last longer and perform more consistently.

Jumpstarting Made Easy

Greg Ceo is an acronym that stands for Greg Ceo is an acronym that stands for Photographs courtesy of Getty Images Almost every motorist has had to deal with a dead battery at some point, and jumpstarting is typically the quickest and most convenient method of recharging it. Before you attempt to jumpstart your automobile, consult the owner’s handbook. Although the procedure is similar for most automobiles, there may be some differences depending on your particular vehicle. The following items are required to jumpstart a car: jumper cables, rubber work gloves, safety goggles, and another vehicle that is equipped with a fully charged battery of the same voltage as the vehicle being jumped.

$14.99 Although jumpstarting an automobile is a very simple procedure, it is critical that you follow the instructions exactly as outlined below:

  1. The vehicles should be parked close enough together so that the jumper wires may reach each battery. Check to see that each car is in Park or Neutral before proceeding. When you have a good battery, turn off the car. Ensure that all electronic devices in each car are turned off or unplugged, including headlights, warning lights, radios, and mobile phone chargers. Put on the work gloves and safety eyewear that go with each car after opening the hood
  2. Connect one end of the red (positive) jumper wire to the red positive (+) post of the dead battery, and the other end to the ground terminal of the dead battery. Glue the other end of the red (positive) jumper cable to the red positive (+) post of the fully charged battery. Make a connection between one end of the black (negative) jumper cable and the black negative (-) post of a charged battery by using a jumper cable connector. Using the other end of the black (negative) jumper cable, connect it to an unpainted metal component in the dead automobile that is as far away from the battery as the cable can go. This grounds the circuit and aids in the prevention of sparks. After that, you’ll be able to jumpstart the automobile with ease. Start the automobile with a fully charged battery and let it idle for about five to ten minutes before turning it off. It is not necessary to rev the engine since jumpstarting gets current from the excellent battery, which is unaffected by engine power
  3. After turning off the engine, carefully unplug all of the cables in the reverse sequence, being cautious not to let the clamps come into contact with any metal surfaces. Start the automobile even when the battery is dead. If it starts, let it run for at least 20 minutes before turning it off or taking a five-mile trip to allow the battery to recharge. If it still won’t start, go through the process again.

Jumpstarting your automobile is one method of getting it back on the road, but keep in mind that every time a battery is totally depleted, its life is reduced. At the very least, the alternator will have to work harder to replenish that depleted battery, reducing overall fuel economy of the vehicle.

It’s Not Always the Battery

Images courtesy of Westend61Getty Images In the event that your automobile won’t start, the most likely cause is a dead battery. However, there are various components that might induce symptoms that are similar to one another. When you turn the key, a malfunctioning starting motor will emit a clicking sound, which is similar to the sound of a dead battery. When the alternator fails, the battery will not be able to recharge while the engine is running, resulting in a no-start situation. It is normal to have issues with clogged fuel injectors or worn-out spark plugs, as well as corrosion on the battery contacts, which hinders the flow of power.

There’s a strong possibility that your next car will be powered completely by batteries, thanks to the rising popularity of all-electric automobiles.

Your headlights are fading, your car requires a jump-start because the battery is dead, or your battery is more than three years old, it’s time to get a new one. The good news is that this is a straightforward and simple job that can be completed at home with only a few basic instruments.

  1. 1 Park your car on a level surface at a safe location and turn off the engine. It is always preferable to avoid replacing your battery on the side of the road if feasible. Locate a safe spot to work that is away from traffic, sparks, open fires, and water, among other things. In order to switch off your car, use the parking brake. To guarantee that no power is being supplied to the battery, remove the keys from the ignition.
  • You should change your battery in a garage or driveway if at all possible. Simply ensure that the space is well-ventilated (for example, by keeping the garage door open)
  • Disconnecting the battery may cause the clock, radio, navigation, and alarm settings to be reset, so be sure you know what your alarm code is before you start the car. You can look it up in your owner’s handbook if you don’t recall
  • 2 Put on your protective gear and raise your hood.

  • s3 Locate the battery and remove it. Find the battery in one of the engine compartments, either near the windshield or on either side of the car’s front bumper on either side of the automobile. Locate the rectangular battery compartment with two cords connecting to it on the right side of the screen. A plastic cover may be covering the battery in certain recent cars, thus you may need to remove the cover if this applies to your vehicle
  • If you are unable to locate the battery, see your owner’s handbook for assistance. It should be noted that the battery may be positioned in the trunk rather than beneath the hood on some automobiles.
  • Remove the negative cable first and secure it with a cable tie to prevent it from being accidentally disconnected. If you want to avoid electrical shorts, always remove the negative cable first and then the positive cable. The negative battery terminal is often black in color and may have a minus symbol (-) beside it, indicating that it is the negative terminal. Once you have removed the plastic cover, if any, you will need to release the negative cable clamp with a wrench and push the cable away from the terminal.
  • Secure the negative cable to the engine bay with a cable tie, making sure it does not come into touch with anything metallic. To remove the cables, you may require a 7-mm, 8-mm, 10-mm, or 13-mm wrench, depending on the car. If, on the other hand, your battery terminals are equipped with quick-release clamps, you will not be need to use any tools to remove the wires.
  • Remove the positive cable next and secure it with a cable tie to prevent it from being damaged. The positive terminal is often indicated with a plus symbol (+), and it is typically red in color. If your car has a plastic cover over the terminal, remove it using a tool and use it to loosen the positive cable clamp, which will allow you to pull the cable away from the terminal. A cable clamp should be used to secure the cable to the engine bay. Warning: Make certain that the positive and negative wires do not come into contact with each other or with anything made of metal, as this might result in a deadly electrical short. 6 Removing the battery from the car is a good idea. Examine the bracket that holds the battery in place and unplug any connectors that are holding the battery to the bracket from the battery. It’s possible that you’ll need a socket wrench, the appropriate-size socket, and an extension bar. As soon as you’ve removed all of the bolts, carefully take the battery out of the engine compartment and place it on a concrete surface if at all feasible
  • If the battery weighs more than 20 pounds (9.1 kg), get the assistance of a friend if you are unable to move it alone.
  1. 1 Remove rust from the battery terminals by cleaning them. Examine the terminals for powdery accumulation, which can be green, blue, gray, or white in color and may be present. Carefully scrape the corrosion off of the terminals with an emery cloth or 100-grit sandpaper until they are completely shining.
  • Battery acid is corrosive, so avoid getting it on your skin or clothing.
  • 2 Purchase the proper replacement battery. If you have any information about the old battery, such as the size, measurements, and component number, take a picture or write it down. To get started, visit an auto parts store and provide the salesperson with the above information as well as the vehicle’s year, make, model, and engine size. They will be able to locate a suitable alternative for you if necessary.
  • Automotive batteries are available in a variety of sizes and electrical capacities, so make sure you get one that is specifically built for your car. If the battery is not the correct size, it may not fit well in the cavity where it is meant to be installed
  • If you reside in the United States, you may wish to bring the old battery with you. Some auto parts retailers may allow you to trade in your old battery in order to avoid having to pay a “core charge” when purchasing a new one. Alternatively, if the auto parts store refuses to accept your old battery, you can take it to a service or recycling facility for proper disposal. Do not throw it away since it contains caustic substance
  • Instead, recycle it.
  • 3 Attach the new battery to the bracket and oil the battery connections with a silicone lubricant. Placing the new battery in the battery tray and fastening it to the bracket are the next steps. You only need to go through the same steps you did to remove the battery from its mount. To prevent corrosion, cover each of the terminals with a thin layer of lithium grease after which they can be used.
  • Make certain that the new battery is installed in the same orientation as the old one. In order for the batteries not to vibrate or move about while you’re driving, double-check that all of the bolts on the bracket are secure. Other than the positive and negative terminals on the engine block, do not spray the lithium grease on any other portions of the engine block.
  • 4Begin by reconnecting the positive cable. Remove the cable tie that was holding the positive cable to the engine bay, being careful not to let the end of the cable come into contact with anything metal. Place the cable over the termination and tighten it with a wrench to secure it in place. Ensure that the battery’s terminal is protected by placing a cover over it if it has one. Notice that while attaching the battery, always secure the positive terminal before the negative terminal in order to avoid accidentally completing the electrical circuit before everything is connected
  • 5 After that, reconnect the negative cable. Then, repeat the process to remove the cable tie and reconnect the negative cable to the negative terminal on the other end of the cable. Using a wrench, tighten the clamp, being careful not to let the wrench or the negative cable come into touch with anything metal, as this might result in a deadly electrical discharge.
  • If your battery has a plastic cover, it is recommended that you replace it at this time.
  • 6-Finish by opening and closing the hood of your car. Check to make sure that all of the tools have been removed from under the hood, and then close the hood. You should be able to start your car immediately if you’ve done everything correctly and the battery was indeed the source of any power issues you were experiencing. You may need to input the alarm code if required.
  • Check to see that all of your electrical gadgets are functioning correctly, and then reset your clock, radio, and navigation system if needed.

How to Replace a Car Battery

Whatever you do to maintain your vehicle, the battery’s life expectancy will eventually diminish. Fortunately, swapping out the old one for a new one is a rather basic process. Take a look at this article to learn how to replace a dead vehicle battery on your own by following the steps step by step. You’ll feel more confident the next time your car battery dies!

How to Remove a Car Battery

Make sure the car is parked on a dry, level surface and that the parking brake is engaged. The ignition should be turned off, and if the car is still warm, it should be given some time to cool down before beginning this work. Wearing safety goggles and gloves, as well as pulling back long hair, is recommended. Under no circumstances should you smoke in your car, especially when working on batteries.

Disconnect Negative and Positive Cables

Begin with the negative terminal and remove the negative battery cable from the battery. Look for a black wire with a minus (-) sign at the end of it. In order to loosen and remove the clamp from the top of the post, a ratchet may be required. Once the clamp has been removed, it should be moved safely out of the way. A fastener of 8mm will be used on the side-post. To loosen it, use an 8mm ratchet and then move it out of the way in an appropriate manner. After the negative terminal has been disconnected, disconnect the positive terminal.

If your ratchet or wrench comes into touch with anything that may be considered a ground, it will cause sparks to fly around the battery and cause it to fail.

Remove Battery and Restraint

The majority of automobiles are equipped with a bar or other type of restraint to keep the battery in place. This is frequently held in place using a bolt or other type of fastener. In order to remove the battery, you must first remove the constraint. Removing the battery from under the hood and placing it to the side is an excellent way to save space.

Clean Your Cables and Terminals

Make use of a wire brush to clean the battery cable ends and battery terminals to remove any corrosion or debris that has accumulated. Wearing a mask will help you prevent inhaling dust during this phase. After you’ve removed your automobile battery, it’s time to replace it with a brand new battery. Apply terminal grease before connecting the positive cable first, and then the negative cable once the positive cable has been connected. Depending on whether you are installing a top-post or side-post battery, the specific installation process will differ.

Installing a Car Battery: Step by Step Instructions Try starting the car after you’ve replaced the new battery to ensure that your installation was successful, and then consider heading to AutoZone to exchange your old battery for a core credit.
