osamio Posted December 31, 2010 Report Share Posted December 31, 2010 I would like to run two batteries with either a bus bar or an isolator.. I'm not sure which yet.. But before i start on that, can a stock alternator handle charging two batteries? I'm not sure the stock amperage of my alternator, i'm sure it's not fantastic..

hdorre Posted December 31, 2010 Report Share Posted December 31, 2010 (edited) How big of an alt and what batts? You may need to charge them at night.

crunkjuice1 Posted December 31, 2010 Report Share Posted December 31, 2010 I just ordered the wiring for second battery setup in preparation for alt upgrade this tax season. From what I read and don't quote me but from what I have read once the amplifiers have leeched on the batteries the alt is still going to have to try to top off batteries and also keep amps going. So it all depends on how much power your running and the amperage of your alt. Let the guys on here know those two things and they will help you out for sure.

osamio Posted December 31, 2010 Author Report Share Posted December 31, 2010 How big of an alt and what batts? It's probably in the 120-130 amp range lol. and the first battery is stock, the second is the direct replacement from autozone.

skittlesRgood Posted December 31, 2010 Report Share Posted December 31, 2010 (edited) bus bars OR an isolator? those are 2 very different things you know. the stock alt will be fine with 2 batteries. i recommend keeping the system down for the last couple min of your drive so the alt has a chance to charge the batts a little before you shut the car off. are you trying to put that autozone battery in the car/trunk? because if its not sealed it'll vent poisonous, corrosive gas into the car.

It's probably in the 120-130 amp range lol. and the first battery is stock, the second is the direct replacement from autozone. I'm running 1000-ish watts. (1700w amp with gains turned down) and headlights are dimming pretty bad.. I have a 0awg ground, 0awg engine block ground, but i haven't done the alternator charge wire because the battery is in the trunk, and it's a bitch.. the stock charge wire is 8 guage i believe Quote 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

I know they're very different, i'm trying to decide if i want to use this battery to run when the car is off, that is, an isolated battery, or if i might just go ahead and use it for more power. and the autozone battery is the recommended replacement, i will use a Y adapter to attach it to the vent hose along with the stock battery.

Do not do this. Get a fully sealed battery so there is no chance of it spilling or leaking. Quote Link to comment Share on other sites More sharing options...
