shazaam Posted September 2, 2010 Report Posted September 2, 2010 If your alternator is set to charge at 15V or higher then yes you can run into problems and cut down on the life of the battery. Suggested charging voltage is 14.4 to a max of 14.9V. Alternators will fluctuate with their charging voltages. When they are cold they will jump up into the 15V range and then drop back down into safe charge voltages when they warm up. This would be ok for charging XS Power Batteries, but if you have a regulator on your alternator and it is regulated to charge at 15V or higher, then you will cut down on the life of your battery. How long can they be "safely" charged at 15+ volts? I'm asking because Steve Meade had an MLA Module on his and now the VCM which I saw was charging at 15.5V on his thread which I quoted here. I just got my VCM in the mail today and installed it and I have it set to 14.8V. I'm just curious. 2004 Chevy Trailblazer: Deck: Pioneer Premier DEH-P980BT Mids: 4 Selenium 6W4P's Highs: 2 AQ Tweeter's + 2 Crescendo Tweeters + 2 Power Acoustik NX-5 Bullet Tweeters Highs Amp: MB Quart Onyx 4.125 Bass: 2 18" DC Audio XL's <-- Soon to be 8 Sundown SA-12's Box: 13.37 Cu Ft @ 35 Hz with 3 8" sonotubes Bass amps: Crescendo BC3500 @ .5 ohms (2nd one coming soon) 325a Singer Alt! 375a at 16+ volts! 2 XS Power D1400's www.youtube.com/user/phukudmss
Nathan @ XSpower Posted September 3, 2010 Report Posted September 3, 2010 To be covered under warranty they cant be charged at all over 14.9V. I have seen them handle 15+ volts for a while though and be fine, but I would strongly discourage it unless you just want to buy new batteries. Once you vent one of the batteries you lose power, and can not get that back.
Pittsburgh 412 Posted September 30, 2021 Report Posted September 30, 2021 Hello. I just purchased a xs power battery (d3400r) from d4s. Before putting it on my xs power battery charger I check the voltage. It's reading right at 15v. Should I still connect it to the charger or just install it? Any help will be greatly appreciated 🙏
Dafaseles Posted September 30, 2021 Report Posted September 30, 2021 I would just slap it in the charger really quick. If it's completely full, the charger should tell you. That charger shouldn't overcharge it 2011 Chevy Silverado under construction My build log here. Check it out!
