Cold cranking amp, cranking amps? (Question)

Cold Cranking Amps (CCA) is a rating used in the battery industry to define a battery’s ability to crank an engine in cold temperatures. It measures how much current (measured in Amps) a new, fully charged 12V battery could deliver for 30 seconds while maintaining 7.2V at 0°F (-18°C).

  • Cold Cranking Amps (CCA) or Cranking Amps (CA) are ratings used when referring to the current (power) that a car battery can output. The difference between Cold Cranking Amps and Cranking Amps is that CCA is measured at around -18 degrees Celsius while CA is measured at only 0 degrees Celsius.

How many cold cranking amps do you need?

The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). CCA rating is an indication of a battery’s ability to deliver a sustained amp output at a specified temperature.

What is the difference between cranking amps and cold cranking amps?

Cold cranking amp is abbreviated CCA and cranking amp being abbreviated CA. The difference in these two ratings are cold cranking amp is measured at -17.8 degrees Celsius and cranking amp is measured at 0 degrees Celsius. Cranking amp batteries have more plates and thinner plates than a typical deep cycle battery.

Do you want high or low cold cranking amps?

Well, for years I’ve been telling you that the one criteria – cold, cranking amps. Well, that’s still very important, because cold, cranking amps tells you the ability of the battery to do work right now. And the higher the cold cranking amp rating of the battery, the better it is for your car.

How many amps is a CCA battery?

But for a rule of thumb, you can divide the CCA by 7.25 to get the calculated Ah. For instance, if your battery is marked with a 1450 CCA, it represents 200 Ah. A battery of this rating should last for 25 hours while producing power of 8 amps.

How many cold cranking amps do I need for a 350?

The Chevrolet 350 uses a cold-cranking battery with group size 31T. The battery is powered by 350 amps. If the battery is dead and will not take a charge, it will need to be replaced.

Is it OK to use a higher CCA battery?

Many would agree that the higher the CCA rating, the better the battery is for your car. Batteries with Higher CCA ratings also tend to be larger. They will still work in your car but may not fit in the battery tray. Overall, a higher CCA battery can be more reliable and last longer.

Is 400 amps enough to start a car?

400 to 600 amps will be more than enough to jump-start any normal, consumer vehicle. Commercial vehicles may require up to 1500 or 2000 amps. Compact and small vehicles can be boosted with as little as 150 amps.

What car battery has the most cold cranking amps?

Our top pick for the best Car Battery for Cold Weather is the Optima Batteries 8002-002 34 Red Top. Its 800 CCA and 50-amp reserve capacity are enough to start and power your car regardless of the weather conditions.

Do higher CCA batteries last longer?

The battery with the highest CCA rating will last the longest. It is important to pick the right battery for the right application and climate. Batteries that are built with reinforced plates and a high lead content will usually last longer than batteries designed for maximum cranking performance.

Can a car battery lose cranking amps?

As your car battery loses capacity, cold cranking amps decrease. Discharging most of your battery’s capacity by using it in this manner for too long and then recharging it through driving can cause the sulfur in the electrolyte solution to stick to the lead and create other damage to the plates in the battery.

What does MCA mean on a battery?

CCA is the cold cranking amp rating which tells you how many amps will be delivered to the engine in cold temperatures. MCA or marine cranking amps is conceptually the same rating, however, the CCA rating is based on amps delivered at 0℉ and the MCA rating is done at 32℉.

Can cold cranking amps increase?

Expert Reply: In order to achieve maximum cranking amps you will want to wire your two 12 volt batteries in parallel (see photo). The output of 12 volts will remain the same but the capacity and cranking amps will become the sum of the two batteries.

What Is “Cold Cranking Amps (CCA)”?

Cranking Amps (CCA) is a rating used in the battery business to describe a battery’s capacity to start an engine when the temperature is below zero degrees Celsius. If a new, fully charged 12V battery can produce 30 seconds of current (measured in Amps) while retaining 7.2V at zero degrees Fahrenheit (-18 degrees Celsius), it is considered to be successful. So, how many Cold Cranking Amps does an internal combustion engine require to operate properly?

How Many Cold Cranking Amps Are Required To Start A Car?

The amount of cranking power required by an automotive battery to start an engine varies. It is influenced by a number of parameters, including the engine’s size, temperature, and viscosity of the engine oil. It is possible that the cranking power required by a 4-cylinder engine is less than that required by an 8-cylinder engine. When the vehicle manufacturer specifies the original equipment (OE) car battery, he or she takes all of these considerations into consideration. Cold Cranking Amps (CCA) are typically measured as 1 Cold Cranking Amp per cubic inch of engine displacement (2 CCA for diesel engines).

1L is approximately 61 cubic inches (CID).

What is the relationship between these figures and the CCA of a vehicle battery?

So, now that we’ve gotten the math out of the way and determined how many Cold Cranking Amps you’ll require, let’s have a look at some frequently asked questions.

9 Cold Cranking Amp Related FAQs

Here are some questions about the CCA rating, as well as the solutions to those questions:

1. Why Is Cold (Instead Of Hot) Cranking Amps Used?

It is more difficult to start an engine in a cold environment than it is in a warm one. The starting battery must be able to give huge quantities of power to the engine in a short period of time – generally within 30 seconds following a rapid drain. So the amp value generated at low temperatures indicates the worst-case situation. What is the relationship between temperature and cranking power? The engine and battery fluids are affected by the cold temperature. When the engine is cold, the viscosity of the engine fluids increases, making it more difficult to start.

Not only that, but when the temperature drops, the voltage of the battery drops, indicating that the battery has less electrical energy.

To explain, a battery at 18°C may supply twice the power of a battery at the same temperature as when it is at -18°C. As a result, depending entirely on Hot Cranking Amps (HCA) may be deceptive and misleading.

2. Who Defined The CCA Test?

Global regulations were established as a result of the negative impact that high temperatures have on the engine and automobile batteries. In addition, some organizations, such as the Society of Automotive Engineers (SAE) and the German Institute for Standardization (DIN), have developed standards for the Cold Cranking Amp (CCA) and the Cranking Amp (CA) measurements, respectively. The SAE J537 Jun 1994 American Standard provides the foundation for the starting battery test for Cold Cranking Amps, which is frequently utilized by battery manufacturers.

The output amp of the battery is measured.

3. Where Does The Term “Cranking Amps” Come From?

A hand crank was used to start the engine before the advent of the contemporary battery-powered automobile starting technology. This was a hazardous undertaking that needed a great deal of strength. Cadillac, on the other hand, debuted the electric starter motor in all of their models in 1915, which relied on a starting battery that supplied enough power — known as ‘cranking amps’ — to start the engine. In addition to giving rise to the phrase Cranking Amps, this breakthrough also sparked the creation of the automobile battery business.

4. What Is CA?

The Cranking Amp (CA) is also referred to as Marine Cranking Amps in some circles (MCA). What is the significance of the word ‘marine’? The Cranking Amp test is conducted under the same conditions as the Cold Cranking Amp test, but at a temperature of 32°F (0°C). It is a more applicable rating for a battery inwarmer or for marine situations, where temperatures below freezing zero degrees Fahrenheit (-18 degrees Celsius) are uncommon. A greater amp value will be obtained due to the warmer test environment than the lower CCA number would be obtained.

5. What Are HCA And PHCA?

The HCA and PHCA are battery ratings that are similar to the CA and CCA, with a few changes in the conditions under which they are tested.

A. Hot Cranking Ampere (HCA)

The Hot Cranking Amp, like the CA and CCA, measures the current that a fully charged 12V automobile battery can deliver for 30 seconds while maintaining a voltage of 7.2V, but at an elevated temperature of 80°F (26.7°C). When used in a warm climate, the HCA is designed to make it easier to start applications since battery power is readily accessible.

B. Pulse Hot Cranking Ampere (PHCA)

Using the Pulse Hot Cranking Amp, you may find out how much current a fully charged 12V battery can provide for 5 seconds while keeping the battery’s terminal voltage at 7.2V when operating at 0°F (-18°C). The PHCA grade is intended for use with batteries intended for use in the motorsports sector.

6. Should The CCA Rating Drive My Car Battery Purchase?

Using the Pulse Hot Cranking Amp, you may find out how much current a fully charged 12V battery can provide for 5 seconds while keeping the battery’s terminal voltage at 7.2V at 0°F (-18°C) constant. A battery with a PHCA rating is intended for use in the automobile racing business.

7. How Many CCAs Do I Need In A Jump Starter?

A 400-600 CCA jump starter should be sufficient for an average-size automobile (which covers anything from small SUVs to light trucks). A bigger vehicle may require more amps, maybe as much as 1000 CCA. The amps required to jump-start a car will be less than the CCA of the automobile battery. It’s also important to remember that a diesel engine demands more amps than a gasoline engine. What about Peak Amps, do they matter? In the case of a jump starter, the Peak Amp is the largest amount of current that it can generate during the initial burst.

Even while a battery can only deliver the peak amp for a few seconds, it can keep the cranking amps going for at least 30 seconds with proper care.

Keeping a jump starter in your vehicle is an excellent method to avoid being stranded in the event of a dead battery.

They frequently have additional functions like as a built-in torchlight and a power bank for accessories, allowing you to avoid having a dead battery and a dead phone at the same time!

8. What Should I Consider When Getting A Battery Replacement?

A breakdown of the characteristics to look for in a new battery is as follows:

A.Battery TypeAnd Technology

Which battery type do you require: a starting battery or a deep cycle battery? Both lead acid batteries and AGM batteries perform these roles, and they are both good choices. Lithium batteries, on the other hand, offer a longer battery life but are classified in a distinct category because they are typically used in electric vehicles. Depending on your needs, you can be interested in certain battery manufacturers for their technology, such as the Odyssey battery, which has very thin battery plates with a high lead concentration, or the Optima battery, which has spiral-wound cells, among others.

B. Cold Cranking Amps (CCA)

CCA is a measure of a battery’s ability to start when exposed to cooler temperatures. Purchase a battery with a CCA rating that is the same as or slightly higher than the one you are currently using.

C. Battery Group Number

Batteries are classified into groups based on their physical dimensions, terminal placements, and kind of battery. It is generally determined by the manufacturer, model, and engine type of a vehicle.

D. Reserve Capacity (RC)

Reserve Capacity (RC) is a measurement of the number of minutes that a 12V battery (at 25°C) can supply a 25A current before its voltage decreases below 10.5V. If the vehicle’s alternator fails, it will normally display how much reserve power (measured in time) you will have available.

E. Amp Hour Capacity (Ah)

In electrical engineering, one amp hour (Ah) is defined as the entire amount of power that a 12V battery can supply for 20 hours before it is completely depleted (that is, the voltage drops to 10.5V). For example, a 100Ah battery will provide 5A of electricity for 20 hours if it is fully charged.

F. Warranty Coverage

The battery should come with a no-hassle guarantee that covers a time range for free battery replacement. As a result, if the replacement battery proves to be defective, you will have the option to replace it. If it’s too much trouble to figure it out on your own, you may hire a mechanic to take care of the selection and installation for you.

Wrapping Up

While the Cold Cranking Amp rating indicates a small aspect of your battery’s performance, it is crucial to consider when choosing a battery. However, it should not be the sole criterion for choosing. Please keep in mind that these figures are based on a brand new, fully charged battery. Other elements, including as internal chemistry, charging circumstances, and so on, will have an impact on how well it operates over time and in real-world scenarios.

At the end of the day, all you require is a battery that will consistently start your vehicle. And if your battery does begin to malfunction, contact RepairSmith for expert guidance and assistance!

What Are Cold Cranking Amps & What does CCA Mean?

The Cold Cranking Amp rating is one aspect of your battery’s performance, and it is crucial to consider when choosing a battery. The only criterion for selection, however, should not be this one. Take note that these figures are based on a brand new, completely charged battery. Other elements, including as internal chemistry, charging circumstances, and so on, will influence how well it operates over time and in real-world scenarios. At the end of the day, all you need is a battery that will consistently start your vehicle.


This test, which is based on the DIN standard, is similar to the SAE standard in that it is similarly performed at -18°C, but it drains the battery to 6 Volts at the stated Cold Cranking Amp instead of the required Cold Cranking Amp. In order for the Voltage to achieve 6 Volts, it must be at or above 9 Volts after 30 seconds and it cannot take more than two and a half minutes to reach that voltage.


Another widely used standard is the Japanese Industrial Standard D5301:1999. It is necessary to do the testing for this standard at -15°C, however the test is carried out at 10s or 30s to 6 Volts with 150A or 300A (depending on the size of the battery). Despite the fact that this is an excellent criterion for evaluating the battery, it does not produce real Cold Cranking Amps. All of the standards described in this blog are linked to SLA automotive batteries, not power sport, lithium automotive, or lithium power sport batteries.

It’s worth noting that there are currently no Cold Cranking Amp standards for lithium batteries, which is a curious state of affairs.

Our next blog will discuss the requirements for power sport batteries, as well as other CA/CCA concerns that pertain to lithium batteries, so stay tuned.

What is the difference between Cold Cranking Amps and Cranking Amps ?

CCA (Cold Cranking Amps) and CA (Cranking Amps) are ratings that are used when referring to the amount of current (power) that a car battery is capable of producing. In order to distinguish between Cold Cranking Amps (CCA) and Cranking Amps (CA), CCA is measured at temperatures around -18 degrees Celsius and CA is measured at temperatures around 0 degrees Celsius. From the interior of the battery, the more the number of plates and the thinner the plates are, the greater the Cold Cranking Amp is owing to the increased surface area of the battery.

The overall power that a battery can give in more than 15 seconds is more important to engineers when designing a beginning battery than the capacity per amp hour required in a deep cycle battery throughout the design process.

Why Cold Cranking Amps matter?

In the process of purchasing an automobile battery, you will discover that there are two crucial features that you should pay attention to. Two characteristics distinguish it: one is its storage capacity, which is measured in Ampere hours (Ah), and the other is its cold cranking amperes (CCA) (CCA). The standard automobile battery has a capacity of 60 Ampere hours. You must ensure that the battery you choose has the capacity to store enough energy to meet your demands over an extended length of time.

  1. Cranking current refers to the current necessary to start an engine after it has been allowed to cool down to its operating temperature (the temperature of the surrounding environment).
  2. The amount of storage space available has no bearing on whether or not your automobile can be started in a chilly climate.
  3. In a 60 Amp battery, 750 Cranking Amps can quickly exhaust the battery’s capacity, resulting in the battery lasting just a few decent cranks.
  4. If your battery is in poor condition and your Cranking Amp has decreased to, say, 200 Cranking Amps, you may be unable to start your car, especially if your vehicle demands a significant amount of Cranking amperage in extremely low temperatures, as described above.

The gap between Cold Cranking Amps and ampere-hours is comparable to the difference between the maximum speed a sprinter can achieve in a 100-yard dash and the stamina necessary to complete a marathon. Cold Cranking Amps are used to measure the power of a motor.


As a precaution, if you live in a cold climate, it is advised that you replace your batteries every 2-3 years, or more frequently depending on the size of your car. If you are traveling an area that you have never been before, prepare for the worst in a cold-weather setting by installing a fresh new battery in your vehicle before you arrive. When deciding whether or not to replace your battery, be sure that the new battery has a CCA rating that is equivalent to or more than the old one. Canbat provides a large selection of start-stop batteries with CCA ratings ranging from 950 to 950.

The phrase ‘I’m going to get the battery with the most cold cranking amps I can find’ is heard frequently when individuals go battery shopping. What if that’s not the greatest method to go about choosing a battery? On a lot of occasions, the answer is ‘no.’ To understand why, we must first define what cold cranking amplifiers are and how they work. A series of standardized tests developed by the Battery Council International allows all battery manufacturers to list specifications for their batteries based on the results of those standardized tests.

  1. One of the measures that may be derived from those standardized testing is the amount of cold cranking amps (CCA) that a battery is capable of generating on a cold start.
  2. For this test, they placed a battery in a cold environment (0°F/-18°C) and measured the discharge load in amperes that a fresh, fully-charged battery could produce for 30 seconds while maintaining terminal voltage equal to or higher than 1.20 volts per cell.
  3. Anyone who lives in a cold region and drives a high-mileage diesel truck will tell you that certain vehicles take a long time to start, whether it is due to high compression engines, extremely low weather, or a combination of the two.
  4. Is it possible that someone may need to start a car at temperatures lower than 0°F or crank an engine for more than 30 seconds, or both, at some point in their lives?
  5. Those are, however, the outliers rather than the rule.
  6. Consequently, should I choose a battery based on its CCA rating?
  7. Is it reasonable for a Corvette owner to choose a replacement battery based on the fact that it has a high cranking power at sub-zero conditions, given this knowledge?

What about a Florida resident who owns a Duramax diesel?

Even though the engine requires more starting power than an usual engine, it is unlikely that it is essential to overpurchase a battery based on cranking amps that may never be used.

Why did CCA Ratings become so popular in the first place?

Similar to how sports car manufacturers talk about how much horsepower their engines have, battery makers prefer to brag about how well their products operate in comparison to competitors.

Despite the fact that more is often preferable, it is not always necessary, and it is often more expensive.

Many batteries are also rated in terms of cranking amps (CA), which is a useful feature (also sometimes referred to as Marine Cranking Amps or MCA).

Because of the greater temperature, the cranking amps figure will be larger than the CCA value; but, you already know what that means to a battery marketer: BIGGER IS BETTER!

What Specification Will We Be Able to Proclaim Next?

You’ve undoubtedly seen some advertisements that boast about ‘hot cranking amps’ or ‘pulse cranking amps,’ which boast even larger figures than the ratings for cold cranking amps or cranking amps.

It’s possible that you’ll see one of our commercials that makes mention to five-second bursts of power.

Therefore, it makes logical to offer a specification that more properly represents what the majority of people observe in real-world application.

This takes us full round to the subject of cold cranking amplifiers.

While the importance of this specification in a purchase depends on the application, for most people it is at the very least a starting point when shopping for a new computer.

When a battery is brand new and completely charged, it should be capable of knocking it out of the park.

While the SPIRALCELLs of OPTIMA batteries are connected by durable cast straps, the flow of current via the SPIRALCELLs is far higher than through the welded connections seen in ordinary flooded batteries.

Whether you have an OPTIMA battery in your car or another brand, you can make cold starts simpler in the winter by utilizing anOPTIMA Digital 400 battery charger and maintainer in conjunction with your vehicle.

Even cars that are driven on a regular basis might benefit from having their batteries topped off by a high-quality battery charger, especially when the temperatures drop significantly.

Cold cranking amps

In this post, we’ll cover topics such as what cold cranking amps are, what the cold cranking amps chart shows, the difference between C CA and CA, and the symptoms of a low cold cranking amps battery. Finally, I’ll give a quick explanation of what a good CCA rating for a car battery is. One issue that almost everyone who lives in a cold area will have to ask themselves at some time in their lives is, what exactly is CCA and how does it benefit them? It is possible to describe Coldcranking Amps (abbreviated as CCA) simply as a rating that determines the capacity of a car battery to start the vehicle’s engine in freezing temperatures.

Cranking amp is another phrase that technicians use to describe their work.

Cold cranking amps chart

The relationship between battery capacity and CCA is seen in this CCA chart. Various types of batteries are shown separately in the data: high performance and maintenance-free, maintenance-free, YuMicron, and conventional. The graph clearly demonstrates that the bigger the capacity of the battery, the greater the number of CCAs produced by the battery.

Cold cranking amps vs Cranking amps

Normally, you would see automotive professionals refer to the amount of power a battery can deliver to your battery while starting the engine using either the CCA or CA ratings, respectively. However, have you ever considered what the distinction is between these two grades, given that they are typically comparable in sound? The solution, on the other hand, is rather straightforward! When it comes to cold cranking amps and cranking amps, the difference is determined by the temperature at which these values are calculated.

How many cold cranking amps do I need?

The amount of CCA you receive is determined by the type of car you are driving. Depending on the type of car you’re driving, 400 to 600 amps should be plenty to get it started. This figure ranges between 1500 and 2000 for commercial vehicles, whereas it is just 150 for extremely tiny automobiles. However, keep in mind that this figure changes depending on the age of the car, the temperature, and the state of the battery. The number of cold crank amps required rises when the temperature is too hot, the car is out of date, or the batteries are close to being dead.

What is a good CCA rating for car battery?

For a typical consumer automobile, more than 400 CCA are required to get the vehicle started. On the other hand, the more cranking amps the battery has, the more smoothly it will start, and the battery will last a longer period of time.

Low CCA Battery Symptoms

There are four signs that indicate low C CA, and they are as follows:

  1. The engine turns over but does not begin to run
  2. Your car’s headlights are a little less bright than normal
  3. Even if the automobile starts well on a warm day, it has trouble starting when the temperature is too low. When the automobile engine starts, you notice that it makes an unusual noise.

Car battery CCA too low?

If you have recently changed your battery and discovered that your automobile battery’s CCA is also low, this article is for you. When that happens, it’s time to swap out the old battery for a new one. If the CCA is not low, it is possible that there is another cause for your automobile engine not to start correctly. If you have a digital multimeter, you can perform the necessary tests on your own.

At what percentage of CCA should a vehicle batteries be replaced?

A battery’s cranking amps are intended to be more than the amount of power necessary for a certain application. It compensates for the CCA reduction that occurs during battery usage for a certain amount of time. When should you replace your vehicle battery based on the CCA rating it has? In this case, it will depend on the sort of vehicle you are operating. Consequently, you must determine the minimum amount of cranking amps necessary to get your car started before proceeding. Then determine how many amps your battery is capable of producing.

  • However, if the needed amps are greater than what the battery is capable of supplying, it is time to replace the battery altogether.
  • FAQs: Is it necessary to use cold cranking amps to start a diesel engine?
  • When just one battery is used to power your diesel engine, you’ll need more than 1000 cold-cranking amps to meet this requirement.
  • In order to start a V8, how many cold cranking amps do I require?
  • To ensure that the engine runs smoothly in cold weather, the battery installed with the v8 must have a greater Cold-cranking amp rating.
  • However, keep in mind that a variety of additional factors come into play, such as the age of the vehicle, the state of the battery, and the weather.
  • The amount of cold-cranking amps required varies depending on the type of engine and how old it is on board your boat.
  • In general, the greater the amperage and CCA values, the better the performance of your boat.
  • If you live in a cold climate, it is critical to measure the cold-cranking amps at least once a month to ensure proper operation.

In the event that you don’t pay attention and your battery fails to produce the needed CCA, you may expect to have a difficult day on a snowy morning.

Final Thoughts!

In this essay, I’ve attempted to cover every aspect of CCAs that you could be interested in learning more about. I want to underline once more that you should verify the CCA ratings of your battery before purchasing it. Furthermore, when the warranty term is about to expire, make sure to examine it on a regular basis. If you do this, you will avoid having to deal with an unforeseen problem while starting your vehicle’s engine on a frigid winter morning. Of course, no one loves it when it happens!

What Are Cold Cranking Amps?

It is likely that you have already experienced this personally, but if your battery isn’t adequate to the effort, your automobile will not start. There are a variety of reasons why a battery could abruptly fail, but one important element to consider is the cold cranking amps it produces. What are cold cranking amps (CCAs) and how do they work? Remember that they are a crucial characteristic of automobile batteries when you are out shopping for one the next time you do your research on them.

Start Power

This means that the battery must deliver enough initial power to the starting motor in order for the engine to turn over and begin the combustion cycle. Using a chemical reaction that occurs within the battery, batteries provide a direct electrical current that may be used directly. You have a variety of alternatives and ratings to choose from when buying batteries since there are various distinct types of battery designs to consider. According to your vehicle’s owner’s manual, the recommended battery should be specified; however, depending on your geographic location, you may want to consider the CCA rating in order to select a battery that will perform well over the long term and not leave you stranded in the middle of nowhere on a freezing morning.

Cranky Mornings

It may not come as a surprise to find that low temperatures have a significant impact on the performance of a battery. For starters, the cold makes engine oil thicker, increasing the internal resistance that the starter must overcome while starting the engine. The chemical reaction that generates electricity from within the battery is also delayed, as is the vaporization of fuel required for combustion, all of which are affected. All of this implies that you’ll likely have to crank the starting for a longer period of time, which will deplete the battery more quickly than typical on a very chilly morning.

In electrical engineering, the Cold Cranking Amp rating is the maximum number of amps a fully charged battery can produce at 0 degrees Fahrenheit for 30 seconds while maintaining at least 7.2 voltage.

Trucks require a greater rating than the normal passenger car, which is why you will see a broad range of 350 to 650 CCAs on the shelf for most passenger vehicles.

Unlike a CA rating (which is rated at 32 degrees Fahrenheit, hence the figures are different), CCA shows how efficient your battery will be if you reside in an unusually cold environment where the temperature often dips below freezing. As long as the CCAs of your new batteries are at least as high as the CCAs of your original battery, it is not required to get a battery with the highest CCA rating if you reside in a temperate or warm area. Once again, the first place to check for this information is in your vehicle’s owner’s handbook.

Consider include this in your winter preparedness strategy to ensure that you do not be caught out in the cold this winter.

What are Cold Cranking Amps? — State Street Auto Repair

A series of standardized tests developed by the Battery Council International allows all battery manufacturers to list specifications for their batteries based on the results of those standardized tests, which are then used to determine the quality of their batteries. One of the measures that may be derived from those standardized testing is the amount of cold cranking amps (CCA) that a battery is capable of generating on a cold start. When it comes to starting an engine in cold temperatures, CCA is a rating that defines a battery’s ability to do so.

  1. The higher the CCA rating, the greater the starting power in the battery.
  2. Generally speaking, it is easier to start an engine in a warm environment than in a cold one.
  3. Battery starting power deteriorates as the battery ages, so a battery with higher starting power should give you more confidence over time.
  4. Replacing a battery with a battery that has a lower CCA than the original equipment may result in poor performance.
  5. Even though some areas of the U.S.
  6. A battery should meet or exceed the manufacturer’s recommendations for cranking amps (or cold cranking amps), but in most cases, buying a battery with an extra 300 CCAs likely isn’t necessary.
  7. If you have questions about CCAs or whether you should consider additional CCAs for your next battery replacement,State Street Auto Repaircan help!

How many CCA do you REALLY need?

CCA, MCA, PHCA, and HCA are all battery current ratings that measure the amount of current a battery can supply in order to crank a vehicle’s motor. In the battery industry, cold cranking amperes (CCA) have been regularly used for many years to compare batteries as a bench marking measurement. ‘The higher the CCA, the better it is, and the longer it will endure,’ the notion goes. Therefore, many battery makers have developed batteries to have overly high CCAs at the cost of other more important design aspects in order to maximize profits.

  • The use of additional battery plates and greater CCAs perform well in cold areas; but, in warmer climates such as Australia’s, corrosion, water loss, vibration, and prolonged idling may cause this design to fail prematurely.
  • In the industry, CCA (Cold Cranking Amperes) is the most often used rating.
  • CCAs are significant, but they are not the greatest metric for hotter or more humid circumstances, such as those seen in Australia.
  • MCA (Marine Cranking Amperes) or CA (Cranking Amperes) is a measurement of the current that a fully charged battery can deliver for 30 seconds while maintaining a voltage of 7.2 volts (12 volt battery) at a temperature of 0°C.
  • Calculating at this temperature enhances the battery’s cranking capacity by roughly 20 percent when done at this temperature.
  • With this in mind, it is critical to verify that you are comparing apples to apples when comparing data.
  • A battery operating at 18°C produces double the power of a battery operating at -18°C.

HCA is a battery rating that is particularly designed for use for starting applications in warm settings.

A fully charged battery’s ability to supply 5 seconds of continuous current while maintaining a voltage of 7.2 volts (12 volts from the battery) at a temperature of -18 degrees Celsius is measured in PHCA (Pulse Hot Cranking Amperes).

In reality, the 5 second cranking period is more practical and offers sufficient cranking to start the engine, with the extra benefit of the battery being smaller in size and lighter in weight than previous models.

When starting an engine, the amount of current required varies from vehicle to vehicle and is based on factors such as engine size, circuit resistance, temperature, engine oil viscosity, and accessory loads, among others.

When a car manufacturer specifies an original equipment (OE) battery, all of these considerations are taken into account as well.

Several instances of current demands placed on a battery by electrical equipment within a vehicle are shown in the following chart from BCI (Battery Council International).

Radio 0.5-5AW (0.5-5 watts) 7.5 AH for the windshield wipers 17-18AH for the headlamps (Low Beam, Dim).

Parking lights are numbered 4-10AB.

2-4AB are the outside lights.

(One window): 5AA for the Power Window.

low-voltage (heating and air conditioning): 10-14AH The Rear Window is eated.

The power seat motor weighs between 10 and 13 pounds.

Winter Starting (Petrol): 250-350 pounds; Winter Starting (Diesel): 450-550 pounds.

Delco Remy, a renowned vehicle electrical components manufacturer in the United States, has placed warnings on its starting motors concerning the hazards of high CCA causing harm to them.

With such a diverse selection of similar-looking black batteries available in the market place, all claiming to have the highest CCA ratings, it can be difficult to determine which battery is the best appropriate for a given vehicle or application in question.

Make no mistake about it: big CCA numbers are not indicative of quality.

How to Convert Cold Cranking Amps (CCA) to Amp Hours (Ah)

Because of one very simple reason, the conversion between Cold Cranking Amps (CCA) and Amp Hours (Ah) is not a straightforward one: Cold Cranking Amps (CCA) describe the ability of the battery to provide the high currents required for starting/cranking internal combustion engines for a period of 30 seconds or less, whereas Amp Hours (Ah) describe the capacity of the battery and its ability to provide a specific current for a period of time, typically 20 hours or less.

Essentially, Cold Cranking Amps (CCA) and Amp Hours (Ah) both reflect the capacity of a battery and its ability to give current for an extended period of time – they are just two extremes of the battery’s capacity and capability to provide current.

Group 24 76 Ah, 840 CCA 85 Ah, –
Group 31 100 Ah, 1000 CCA 120 Ah, –
Group 34/78 50 Ah, 800 CCA 65 Ah, 850 CCA
Group 35 44 Ah, 720 CCA 60 Ah, 740 CCA
Group 47 (H5, L2, 55L2) 60 Ah, 600 CCA 50 Ah, –
Group 48 (H6, L3, 66L3) 70 Ah, 760 CCA 70 Ah, 750 CCA
Group 49 (H8, L5, 88L5) 92 Ah, 850 CCA 90 Ah, 850 CCA
Group 51 (51R) 60 Ah, 700 CCA 60 Ah, –
Group 65 75 Ah, 850 CCA
Group 75 55 Ah, 760 CCA 55 Ah, 750 CCA
Group 94R 80 Ah, 800 CCA
Group YTX20L-BS 18 Ah, 270 CCA
Group YTX24HL-BS 21 Ah, 330 CCA
Group YTX30L-BS 30 Ah, 385 CCA

It is important to note that these are ‘average’ values because there can be significant differences between batteries within the same BCI group – for example, Optima batteries are well-known for their ability to crank large engines despite having a relatively lower capacity (and weight!) due to the spiral-wound cells used in their construction. The relationship between CCA and amp-hours varies depending on the battery type, but on average it is as follows: – for starting lead-acid batteries, multiply the capacity (Ah) by 10-16 to get the CCA (Amps) Capacity (Ah) x 8-12 = CCA in the case of dual-purpose lead-acid batteries (Amps) Battery capacity (Ah) multiplied by four or eight equals CCA for deep-cycle lead-acid batteries (Amps) Keep in mind that many manufacturers limit (at least on paper) the maximum current of their deep cycle batteries, highlighting the fact that they are not intended for this type of application.

Always verify the battery’s documentation for the most up-to-date information on its actual capacity and CCA dependence, and use these numbers solely for orienting purposes.
