Ozim Posted July 5, 2013 Report Share Posted July 5, 2013 I have two d3100 sat for one year. One read 11.5v and the other one read 12.5v. I am charging the 11.5v at 2amps, just to be safe rather than 15amps. Is the one with 11.5v done? Do I need to replace it? I know the 12.5v is ok. I am using the powermaster charger.

CortezDTV Posted July 5, 2013 Report Share Posted July 5, 2013 Charging at 15 amps is better....

Rockford96 Posted July 5, 2013 Report Share Posted July 5, 2013 I thought slow charging over a longer period is better?

CortezDTV Posted July 5, 2013 Report Share Posted July 5, 2013 Big x's batteries need the 15 amp charge And if there has been any sulfa facatuon incorrect spelling u know, it helps to break it off the lead (agm material) in the batteries Quote SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...
Ozim Posted July 6, 2013 Author Report Share Posted July 6, 2013 I measured 12.3v while charging at 2 amps for few hours then switched to 15amps now. I'll see how it go. Im hoping it will be okay *crossed finger* Quote '91 Honda crx - TOTALLED 200amps rebuilt Iraggi alt 2 d3100 Mojo [email protected] 2 15's DC XLm1 in 7.2cubes, 2 6" aeroports tuned to 32hz Link to comment Share on other sites More sharing options...
Ozim Posted July 7, 2013 Author Report Share Posted July 7, 2013 after 24 hours sat, one read 12.8v (was 11.5v), the other one read 12.9v (was 12.5v). Seems they're good to go. hope it'll hold up.

SnowDrifter Posted September 4, 2013 Report Share Posted September 4, 2013 after 24 hours sat, one read 12.8v (was 11.5v), the other one read 12.9v (was 12.5v). Seems they're good to go. hope it'll hold up. Since you posted a new thread: Do a couple charge/drain cycles, Hook up an old headlight(or several) until the battery drains down to 10.5-11v or so, take it off, hook it up to the charger on the highest amp charge setting. Do this 2x and I bet they'll perform Quote ~~~~~~~~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...
SnowDrifter Posted September 4, 2013 Report Share Posted September 4, 2013 Or if you can't do that, send them to be with some $$ for return shipping and I'll see what I can do with them Quote ~~~~~~~~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...
