dbslayerdrake Posted April 16, 2012 Report Share Posted April 16, 2012 Okay so even in my head this sounds like such a n00b question but I keep getting conflicting answers when I try to research it. If I have a 320a alternator and 3 d3100's (110ah each = 330a) will the batteries eventually drain because they exceed the output of the alt or am I not quite getting EXACTLY how alternators charge you car's batteries. Any help is appreciated. Link to comment Share on other sites More sharing options...
jrchevy87 Posted April 16, 2012 Report Share Posted April 16, 2012 the only way they will drain is if you pull amps faster than your alt can charge you batteries, trickle chargers put like 5 amps into a 700 or 800 amp batt and it charges it just takes forever lol Jeep Wrangler TJ Hardtop Build Link to comment Share on other sites More sharing options...
