A bigger battery is a band aid for a bigger problem. If you are running so many accessories that your alternator cannot keep up and you are using a battery to pick up the slack, you WILL burn out your alternator.

I go to the drive in for double features all the time. With my stereo turned nearly all the way up I have never had so much as a slow crank.

 

yeah..im not saying that your size batter wont do the job cause it will..

but i like the assurance that comes with the bigger battery..and my alt will do just fine..if it goes it goes

but i doubt it will..im not gonna draw that much current not to mention its only at most 3 years old

 

i have a full system in my truck, and on cold cold morning she fires right up not slow or anything....and i have a 860 amp 775 cca i believe it is

 

I've ran higher capacity batteries in every thing I've had for over 50 years and never had a problem with that burning an alternator or generator up.
