What Does Group Size Mean On A Battery?

A battery group size is an industry standard for automobile batteries that specifies the physical dimensions (height, breadth, and length) as well as the polarity of the battery (where the positive and negative battery posts are located on the battery).

Similarly, What is the difference between a Group 24 and Group 27 battery?

When you compare a group 24 with a group 27 deep cycle battery, you’ll discover that the group-27 product has significantly more mp hours. The manufacturers make this standard discrepancy on purpose. In general, a larger group size has more amp hours than a smaller group size.

Also, it is asked, What happens if I use the wrong group size battery?

A bad battery/alternator combination might cause your alternator to overheat, reducing its lifespan.

Secondly, What does battery group size 35 mean?

Group 35 batteries are medium-sized batteries with a 20-hour capacity in the 44-65 Ah range, 620-850 CCA, 90-130 minutes RC, and other features.

Also, How do I know what group size my battery is?

1st step Examine your old battery for the group size. If you still have the original battery in your vehicle, search for the group size on a label on the battery. The label might be seen on the case’s top or side. The group size is usually a two-digit number that is followed by a letter.

People also ask, How many CCA do I need?

A battery should be large enough to start reliably cold. A battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement is the typical guideline (two for diesels).

Can I put a bigger CCA battery in my car?

The greater the CCA rating, the better the battery for your automobile, it is usually assumed. They may still be used in your vehicle, however they may not fit in the battery tray. Higher CCA batteries are more dependable and last longer in general.

Can a battery be too strong for a car?

Installing a larger-capacity battery alters currents, perhaps causing spikes and surges that might harm the on-board computer or fuse panel. You have a lesser probability of harming the computer, but damage is still possible if the alternator fails. The fuse panel will most likely sustain the brunt of the damage.

Does a bigger car battery mean more power?

In most situations, the terminals will come into touch with the hood and short out the battery, or the physical dimensions will simply not work. The physical size of a battery does not indicate its power or lifetime.

Is 24F the same as 35?

The Group 35 is somewhat bigger than the 24F. Because there is more space within the battery for lead and acid, a Duralast Gold 24F will have a higher CCA rating than a Duralast Gold Group 35. A Duralast Gold Group 35, on the other hand, is superior than a Duralast Silver 24F.

Can I use a 24F battery in a 24 car?

The size of a common battery that suits many Honda, Toyota, Nissan, and Acura automobiles is 24 and 24F. While the size of a 24 and a 24F battery seem to be identical, their polarity is completely different. There are no size variations between these two batteries according to BCI specifications.

Are all Group 24 batteries the same size?

Rather than being used to start an engine, Group 24 batteries are often used as deep cycle batteries. A typical model is 10.5″ long, 6.1875″ wide, and 8.875″ tall. They’re also divided into numerous subcategories, each with somewhat varied dimensions. 24F, 24H, 24R, and 24T are the codes for these.

What is the group size for a car battery?

24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, and 65 are the most frequent battery group sizes. Helpful Tip: Some automobiles can accommodate a battery that is bigger than the one that was initially installed. A bigger battery will often have greater power and reserve time than a smaller battery.

How many CCA do I need for a v6?

For every cubic inch of engine displacement, the rule of thumb is 1 Cold Cranking Amp (2 CCA for diesel engines)

Can a battery have too many CCA?

In general, the CCA standard may always be exceeded. It’s most often done on a warm day with a fully charged battery. The electrical system of the automobile will not be harmed by having greater potential current available.

How many cranking amps do I need for a v8?

For a V8, how many cranking amps do I need? To operate the engine smoothly in cold weather conditions, a battery equipped with v8 must have a greater Cold-Cranking amps. A v8 fitted in a consumer car must have a CCA value of 400 to 500, according to OE requirements.

What does the L mean on battery?

For example, the battery number “YB4L-B” means: Manufacturer reference “YB.” “4”: Ah capacity of the battery (4Ah) “L” stands for polarity (L = left-hand negative terminal).

What does HD mean on a battery?

Oxide of high density

What is the difference between deep cycle and regular batteries?

Deep cycle batteries are not the same as standard batteries. The power produced by regular automotive batteries is shorter. Deep cycle batteries deliver modest but steady amounts of electricity throughout time. This amount of electricity is sufficient to run a vehicle without a motor.

Are MCA and CCA the same?

The cold cranking amp rating (CCA) indicates how many amps will be provided to the engine while it is cold. The CCA and MCA ratings are basically the same, however the CCA rating is based on amps supplied at 0°F, whereas the MCA rating is done at 32°F.

What does 1000 MCA mean on a battery?

Amps for Marine Cranking

What does 690 MCA mean on a battery?

Thus, a 12V battery with a 600 CCA MCA rating will supply 600 amperes for 30 seconds at 32 degrees Fahrenheit before the voltage drops to 7.20V. It’s worth noting that the MCA is also known as the cranking amperes or CA.

Are Group 24 and Group 27 batteries the same size?

The length difference between groups 24 and 27 is 1.8125 inches (46 mm), while the width and height are same (W: 6.8125 inches (173 mm), H: 8.875 inches (225 mm)).

How long will a 24v 200Ah battery last?

A 200Ah lead-acid deep-cycle battery with 50 percent recommended Depth of Discharge will survive for around 3 hours while operating a 400 watt DC load. At a rate of 40 watts per hour, a 200Ah deep-cycle lead-acid battery would power a 400W refrigerator for around 25 hours.

Is a 600 CCA battery good?

When you reside in a chilly country, it is essential to consider the CCA rating. To endure the winter season in a cold location, a cranking amp must be stronger and higher. In a cold environment, a CCA rating of 600 or more is typically regarded appropriate.

What percentage of CCA should vehicle batteries?

More than 400 CCA are required to start a typical consumer automobile.

How many CCA do I need in cold weather?

A battery with at least 600 CCA is required for perfect cold-weather starts (cold cranking amps). The majority of typical automobile batteries have a CCA rating of 300 to 500.

What happens if you put a bigger battery to a car that is not the recommended one?

The battery capacity will have no effect on it other that it will take longer to charge. The alternator’s output is almost entirely used to power the car and any accessories. Any battery’s charge rate is much lower than its advertised capacity.


The “battery group size chart” is a chart that shows the different battery sizes and their respective groups. This can be used to help determine what the best battery for your device is.
