3 features that you should consider when buying a new battery
3 things that you should care when buying a new car battery: Right size, same or high CCA rating, suitable Ah rating.

Battery Size 

Batteries come in a variety of different group sizes. You need to make sure you purchase a battery from the same group as in your vehicle now. This will ensure that it fits perfectly into the car’s battery box.
