sactownstang Posted August 12, 2012 Report Share Posted August 12, 2012 My battery rests at 12.85 after 24+ hours sitting off the charger but it's a quite a few years old. I imagine most people wait till it's 12v and under, Whats the best way to test? Put a load on it and see what it drops to? Link to comment Share on other sites More sharing options...
SilverSPL Posted August 12, 2012 Report Share Posted August 12, 2012 get a battery load tester like the one in the link http://www.amazon.com/ATD-Tools-5492-Carbon-Battery/dp/B002J8LN52/ref=sr_1_9?ie=UTF8&qid=1344783967&sr=8-9&keywords=battery+load+tester Link to comment Share on other sites More sharing options...
bass_stalker Posted August 12, 2012 Report Share Posted August 12, 2012 turn on your head lights and let the car sit for about 4 minutes to take off the surface charge then see where it rests. if it sits above 12.4 i think it is your battery is good. you can also try starting it with the headlights on and listen to how fast or slow it cranks JEEP BUILD PROJECT ANTIBLING.2000 jeep Cherokee.HEADUNITAlpine Cda-9886SUBSTAGE1 acendent 18" audio mayhem motor with a TI basket and tantric parts1 prototype DAT hellfire 1000.1HIGHSStockELECTRICALdb link 0 gaugeKnuconceptz Kolossus 4 gauge1 xs power d3400 under hoodBig 3 upgradeold fourwheeler build The only way to delete your SMD account is for you crawl to steve meades door step on your knees and pleade for his forgiveness and acceptance to be released...He will either grant your wishes.....or choke you with a large piece of 0 gauge and electrocute you by hooking up a solid gold DC 12k at 0.000001 ohm and 10000 volts to your eye sockets and blow your head apart You guys act like you have never clogged a toilet and ran around the bathroom frantically hoping it don't overflow.

n8ball2013 Posted August 12, 2012 Report Share Posted August 12, 2012 anything under a 12.6 is pretty much not good. IT can lead to sulfation. Nathna from xs had a great right up on it.
