paulgroce Posted March 6, 2012 Report Share Posted March 6, 2012 Is it okay to use the stock battery under the hood and have a AGM (glass mat) battery in the back? Or do both batteries have to be the exact same??

dfoland93 Posted March 6, 2012 Report Share Posted March 6, 2012 You can have different batteries 2 of the same is better then 2 different The spot with least resistance LOL. I would ground to a rubber dildo if it had less resistance than a run of 4/0 wiring. how many poeple work there 3 or 4 lol At crescendo HQ? probably 2-3 At the sweatshop in china? 30,000 children No Engine Link to comment Share on other sites More sharing options...

paulgroce Posted March 6, 2012 Author Report Share Posted March 6, 2012 Okay because I have a KHC2000 under the hood and in the trunk. But I was wondering if I put back in the stock under the hood and put the two KHC2000's in the back it would have more power and be good?

SnowDrifter Posted March 6, 2012 Report Share Posted March 6, 2012 Quick thing to note: Normal starter batteries tend to rest ~12.6v in good condition while good AGM batteries rest closer to 13v - so the starter might pose a slow drain to your good batteries. Not sure if it makes a huge difference, but it's something to think about. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
