Wagonized Posted November 26, 2015 Report Share Posted November 26, 2015 Batteries are only meant to be cycled a certain amount of times in total. In my experience they will not accept as much of a charge as they get older.But also, with a brand new battery that has NEVER seen alternator charging, one can train them to sit in the low-mid 14s without much trouble for 20-30 minutes after charger is off. Ever notice, most of the loudest street class SPL cars in the world are never seen running?? BC charging the batt with the alternator prevents a battery from being properly trained by a charger. The loudest street class SPL cars are trailer queens.

dangaranga Posted November 26, 2015 Report Share Posted November 26, 2015 My 2 juicebox agms sit at 13 installed in the truck for a few days then 12.9 for weeks. And they are about a year old. I have had them on a charger only a handful of times over the summer because of #stockalt life at the time. From what ive seen 12.8-13 is about normal Quote Brandon 2000 Furd Ranger supercab 4x4 System: welding wire throughout the truck USalts 390amp Hairpin Juicebox in stock location 8 Banks of maxwell supercaps 2 American Bass Vfl 1100.1 wired to .35 each 2 Fi Audio Sp4 18's ( the DD sc 9918's smoked) Pioneer radio with Soundstream PA mids Powered by a nice sized soundstream 2 channel It's pronounced (dain-ja rain-ja) 2001 2 door focus 1 DD9918 SC Link to comment Share on other sites More sharing options...

moh.vze.com Posted December 22, 2016 Report Share Posted December 22, 2016 I remember back in 2012 when I bought my brand new XS D2400, it measured 12.3V out of the box. I was pissed. They could have at least charged them before sending them to me (bought from audiosavings ). My XP3000 came out of the box at 12.7V Quote DC Audio - Singer Alternators - Knukonceptz - XS Power - Hybrid Audio - Rockford Fosgate - Second Skin Audio - SMD - Sundown Audio - Elemental Designs Link to comment Share on other sites More sharing options...

I don't buy that many batteries so I had high expectations of everything being perfect out of the box =_= It was a good thing they double boxed the battery because the outside box looked beat up: then inside was another box and a lot of foam: Quote DC Audio - Singer Alternators - Knukonceptz - XS Power - Hybrid Audio - Rockford Fosgate - Second Skin Audio - SMD - Sundown Audio - Elemental Designs Link to comment Share on other sites More sharing options...

My XP3000 came out of the box at 12.7V SMH If you read the paper that comes with all XS Power the first thing it tells you in bold italic letters is Proper Charging is Crucial! Charge before initial use! It also even states this in the instruction manuals on the site. http://www.4xspower.com/Dseries-Instructions.pdf As for any new battery no matter what manufacture, or what type it is, or where you bought it you should give it a full charge before use. You have no idea how long that new battery has sat on a shelf at said store or warehouse and this is why you should always give it a full charge. 2 Quote Link to comment Share on other sites More sharing options...
