raytard Posted October 20, 2009 Report Share Posted October 20, 2009 try an intellicharger (kinetik and powermaster have them, and im sure some other brands) they can do a "refresh" charge at a higher voltage to break down sulfates and such and maybe save it but if its that low it may just be time to scrap it.

z71kris Posted October 20, 2009 Author Report Share Posted October 20, 2009 10 amp 12 volt is the best I have, other then the 55 amp start option, but I dont think thats way to go....I am hoping the deep cycle will make it.... 03 GMC Sierra Z71 Ext Cab l 2 15" American Bass XO's l 1 Lanzar HTG2600 l AudioVox 1510D In dash DVD l KnuKonceptz Wiring l Big Three Done with KnuKonceptz KLMX 1/0 l Infinity Reference 6022si 6-1/2" Front Door Speakers l Upgraded to 145A Alt from 105A Alt l Custom Box 2^3 under the rear bench with resined bottom, and about 4 lbs of polyfill Link to comment Share on other sites More sharing options...
Boon Posted October 20, 2009 Report Share Posted October 20, 2009 Er... ahhh... if it's anything other than a VRLA I wouldn't be within 20ft of it when it's charging. Batteries that have gotten that low have usually dropped a cell, when you charge it all the other cells get massively overcharged = kaboom. 10.x volts fo' life!

MECHMAN Posted October 20, 2009 Report Share Posted October 20, 2009 If it has been discharged that far and has set that low for a period of time, it will never be 100%. Even if you can get it to rest at a decent voltage, it's capacity will be a fraction of what it once was, and will perform like a much smaller battery. I would can it, and get a new one. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
