Detailed Comparison Between 24f Vs 27f Battery

Key Points:

  • 24F is smaller so it fits to the most of the cars out there.
  • 27F is bigger but weighs less than 24F and also gives you more reserve capacity.
  • 27F lasts longer than 24F after one-time charge. 

If you are, to begin with a vehicle, the first thing you need is the battery. You have to keep some things in mind before purchasing a battery for your vehicle.

You might be thinking which size of battery should be fit for your car? How much the reserve capacity should be?

However, I have described all the differences and features of 24f vs 27f battery along with a comparison chart. Don’t miss out on that.

24F Battery

24F is a 12 volt 6 cells battery. The dimension of this battery is L x W x H: 10.3 x 6.8 x 9.9 inches. Most of the cars out there rely on 24f batteries because of their versatile features, and longevity.

24f is a bit smaller than the 27f so it fits most of the cars. But if you are not tight on budget you can go for 27f as it’s bigger and has a better Reserve capacity.

  • Smaller so fits to the most of the cars
  • More Cold cranking amps


  • Less reserve capacity
  • Weighs more

I have included some best 24f group batteries out there based on consumers’ reviews.

Before buying a battery, you must be aware of the size. It’s important that it fits perfectly on your cart.

As 27f is larger than the 24f by 2 inches, it can cause trouble fitting into your car. First take note of the battery size your car prefers then go for the battery.

But even if the 27F is bigger, it weighs less than the 24F battery. So it won’t trouble you with extra weight and will give you more reserve capacity.  

Reserve Capacity

Reserve capacity means how long a battery can run the vehicle if the charging system gets damaged.

You might need your battery to hold the capacity till it’s charged again. So, you have to find out if your battery is the perfect one to offer you this needy facility.

As we can see the reserve capacity of 24f is 130-180 minutes in 66-110Ah. When it’s 140-220 minutes for 27f batteries in the 66-110 Ah range. Therefore, the 27f battery gets the advantage here.

According to the consumers, the 27f batteries have more reserve capacity than the 24f ones.

Cold Cranking Amps

CCA basically means the amount of chemical energy a battery can store and release in critically cold weather. It is measured based on zero degrees Fahrenheit temperature.

Your engine will not function if the battery cannot perform under such weather. So, it’s a priority to have this fact right. But experts say 24f has a higher CCA than 27f.

24f batteries usually provide 250 CCA to 800 CCA depending on your batteries’ Amp hour.

Battery Life

Usually, the expectancy of a battery is 3-5 years. But it depends on many things.

You must follow the manufacturer’s instructions and care guide while using. Then again if you look at the size, amp hour, and reserve capacity; 27f gives you the advantage.

Here’s a comparison chart given below. Have a quick look at it.
