[QUOTE="psychoacoustics, post: 6488328, member: 584032"] this is true dont mix and match batteries parasitic discharge is what is happening they will try to equalize back and forth until they are both dead its not as big of a deal for a competiton car cuz they sit on a charger most of the time. if you drive the car and need it to be dependable its more of an issue. if you plan on listening to the stereo for long times and dont plan on starting the car (at the park or a show) an isolator will isolate the starting battery from the stereo battery until the alternator is charging by batteries from the same place at the same time all batteries should be wired in parallel if not you will get 24 volts [/QUOTE]
