I had a dead battery today and so i went to the local auto parts store and the size of battery that was the same as mine had a pretty low cranking amps rating and i wanted something more powerful. So they found a battery that was just a little larger with more cranking amps. The battery fits and works fine. But i was wanting to know if a battery could be too strong for a car and cause problems down the road? Its not like huge or anything, i think its like 250 more cranking amps than the stock battery. maybe a little more.
