Is higher cranking amps better?

In general, for both CCA and RC, the higher the number the better. However, if you live in a cold climate, the CCA rating should be an important consideration in choosing a battery. Conversely, if you live in a high heat climate, you don’t need as much CCA.

What happens if you put too big of a battery in a car?

Installing a larger-capacity battery changes the currents, which could lead to spikes and surges that may damage the on-board computer or fuse panel.
