Batteries should be selected first by "Group Size", then cold cranking amps.
Odds are the wrong group size will not physically fit, or the terminals will
be the wrong type, or on the wrong side.
Looked up your car on Advanced Auto Parts site, group size is 75. They offer
a 600 and 700 CCA battery. They list the OEM battery CCA at 525.
So, yes you should be able to use a 520 CCA battery with no problem.
i think you have either misread or mis-stated, either way, the
bigger battery will be fine. two things to be check:
1. will it physically fit and be held down properly? the fit must
be good side to side and top to bottom. sometimes the hood
will hit battery terminals on top. makes lovely sparks at night.
2. are the terminals correctly located for the cabling you have?
i always buy the biggest heaviest duty battery that will fit. more
cca sometimes comes in handy when boosting others or when
you might have left the lights on in the winter.
Exactly. Forget the group size except as a last resort. Measure what
will fit and put in the largest. Besides, the OP wanted to do just
that, not put a stinking little 520 CCA or smaller in there like it
had. It's not coincidence that the higher CCA batteries also have a
longer warranty. Every year the battery loses a bit of reserve and the
bigger base you start with means you go longer. Some cars won't take a
larger physically sized battery and then you just do what you can.
