[QUOTE="Bass so loud it HZ, post: 8826107, member: 687371"] ³ Ok I put a battery tester on them a lil while back and one was weak but not fully dead. My systems in a 04 jeep grand cherokee so im not sure on the whole ecu thing. I just put a 320 amp alt in with the big 3. Hooked the new battery up today and i am holding charge alot better but if im at full tilt it will drop into the low 12s so i thinl im gonna add another batter. Do I need to charge the batteries or will my alternator charge them enough ? And with that battery being weak is it doing me any good leaving it hooked up ? [/QUOTE]
