Car batteries come in different sizes. They are manufactured to fit different car housing. That being said you simply cannot cement a group 65 battery on a group 27 or 51 casing.

You can also seek help from a professional automobile expert if you are confused about the sizing. A correct size fitting will comfortably sit on the front battery tray. Proper fitting ensures a damage-free ride.

Cold-cranking amp

CCA simply cannot be overlooked when it comes to car batteries. Batteries usually endure varying weather changes and that takes a toll on their power generation. With high cold-cranking amps, batteries tend to grind through and function even in the harshest of weather. Batteries should be able to crank power even at zero degrees Fahrenheit surrounding. Therefore a peaking CCA is super necessary otherwise you might face engine failures or stalls due to low temperature. A battery should also have enough cranking amps (CA) to deal with high temperatures. 

Reserve capacity

Car Batteries must have a good reserve capacity to work proficiently. The best battery should always run for an extended period in a single charge. The more the reserve capacity the better the battery will function and produce optimum power for all the equipment. The reserve capacity is a savior. It works as a backup even if the alternator fails.


As batteries grow older, they tend to have less strength. You have seen it right. Batteries deteriorate over time, therefore we prefer you to grab something as new as possible for the best outcome. Don’t buy a battery that is more than 6 months old. 


Some battery manufacturers claim that their batteries are made to last years after years. You better pick something that has a physical warranty and service. Even though group 65 batteries tend to have a lifespan of 5 years on average. Still, it’s better if you purchase something that has a warranty. So that if there are any mishaps, you could easily have it serviced or changed. Some companies will offer you a 1-year year warranty and others cover it up for 3,4, 5 years or more.
