rickyfromthe407 Posted April 14, 2011 Report Share Posted April 14, 2011 Hey guys, So I ended up having some issues with my D6500 second battery it wasn't getting charged as I had thought, It was only maybe used for 30 minutes or so without being charges, but it was taking around 2000 for that 30 minutes. I need to charge the battery because the voltage was critically low. And I do not have an AGM battery charger. My buddy said throw it on a regular battery charger for a few hours and then take it off. So I put it on my battery charger and its been going for maybe 3 or 4 hours at 10amps and It should be about 14 volts I will go check it in a few with my multimeter. Just wondering what I should do from here. I took it off the charger about 15 minutes ago to check its voltage and it read 12.5 Should I leave it charging at 10amps? The charger is a smart charger so when it sees a full charge it automatically decreases the amps down to a 1amp trickle charge. But still just looking to get some quick answers hopefully I didn't mess the battery up D:?

REMT15 Posted April 15, 2011 Report Share Posted April 15, 2011 (edited) 12.5 volts is the resting voltage with car off? if so thats fine. the only time your going to see 14+ volts is in your car with the alternator charging or if you have a AGM style charger. hope that helped Edited April 15, 2011 by REMT15 Quote Link to comment Share on other sites More sharing options...

But i checked it with my DMM and it read 8.6 so I was like WTF?! I ripped it out, took it to the shop and checked it again and it read 12.4 and I checked it with another DMM and it read 12.7 this was before i threw it on the charger. ( I must have checked the voltage and slipped off a lead when I measured in the car ) So I dropped it on a 10 amp 13v charge for eh id say about 5 or 6 hours I think I took it off at about 9 and started around 3:30 I think give and take some. Either way when I took it off at 9ish it was resting at 12.6-12.7 which I believe is damn good! I am gonna check it again in the morning, I was just going to let it sit out of the car on the test bench ( not charging ) over night, and if its still at 12.7 I will throw it back in my car and start bumping again! Hope all is well. Must have been a fluke. Appreciate the reply! Will keep you updated in the morning.

rickyfromthe407 Posted April 15, 2011 Author Report Share Posted April 15, 2011 Well, Idk man. I charged it for a few more hours on a regulated charger so it ended up charging it at like 5amps for a few hours. I took it off after about 3 hours and it was resting at 13.5 Hope thats not bad. LOL.
