Question: Can you put too powerful of a battery in your car?

Can a car battery be too strong?

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. You have a lower chance of damaging the computer, but with alternator failure, damage is still a possibility. The fuse panel likely will receive most of the damage.

Can too big of a battery hurt your car?

How many watts can a 120 amp alternator handle?
