Trill Posted March 24, 2014 Report Share Posted March 24, 2014 I ordered my D6500 a few weeks ago and decided to put it on the charger in my house for a couple days. The charger is a schumacher SE-5212A and claims fully automatic with engine start. I set it at 10A and Maintenance free deep cycle. It was on for probably 3 days and then I removed it for about 2 weeks. I installed the battery in my truck on Saturday and drove around for about 45 minutes then it sat all day sunday. I went to a doctor appointment today and when I got back to work and shut the truck off I watched the voltage for a few seconds and it was at 13.6 and slowly falling and after 5 hours I went back out to the truck and it was at 12.1v Is my truck draining the battery or is it just not resting properly. I hear it should be between 12.6 and 13.1 I just purchased a Schumacher 15A XC515 and will hook it up to that and see what happens. Glad I didn't hook my D3100 up to the other one I guess. Unless I just have not driven around enough to charge it fully or my truck is draining the battery.. which should not be happening I dont have any amps or accessories hooked up right now. /sigh Quote Minnesota!

EP95 Posted March 24, 2014 Report Share Posted March 24, 2014 You've got parasitic draw from something, Voltage shouldn't drop like that. A computer might not be turning off all the way. Quote Link to comment Share on other sites More sharing options...
hdorre Posted March 24, 2014 Report Share Posted March 24, 2014 Those chargers have a history of overcharging batts iirc.. At "crazy" voltages. That's why I went with CTEK Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
hdorre Posted March 24, 2014 Report Share Posted March 24, 2014 Posted too early.. But maybe it killed a cell? Or maybe damaged a few.

Trill Posted March 24, 2014 Author Report Share Posted March 24, 2014 The only thing I can think of is that my headunit + Nav module and the EQ746 all have constant power + Remote turn on, could those be drawing enough to drain? Or are they not supposed to drain power until the remote wire turns them on? Quote Minnesota! Y U NO GET WARM! Link to comment Share on other sites More sharing options...
EP95 Posted March 24, 2014 Report Share Posted March 24, 2014 (edited) They'll drain a little but not enough to do that, Ima go with Hdorre and say a cells gone bad. Edited March 24, 2014 by EP95 Quote Link to comment Share on other sites More sharing options...
Facekicker Posted March 24, 2014 Report Share Posted March 24, 2014 If you can turn them on without a key in the ignition, those could be a problem. Properly wired with a remote turn on, they should not be causing the issue.

Trill Posted March 24, 2014 Author Report Share Posted March 24, 2014 I just looked at the spec sheet for the charger and says output voltage is 12v. It doesn't say anything about going above that hmm Quote Minnesota! Y U NO GET WARM! Link to comment Share on other sites More sharing options...
Trill Posted March 24, 2014 Author Report Share Posted March 24, 2014 I'm guessing that if I did damage the battery I'm dicked out of warranty? Quote Minnesota! Y U NO GET WARM! Link to comment Share on other sites More sharing options...
Amart88 Posted March 24, 2014 Report Share Posted March 24, 2014 12v batteries need 14.5v for a proper charge. Quote My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
