focalrock4life Posted February 12, 2012 Report Share Posted February 12, 2012 So, what are some signs of XS Power batteries venting their oxygen? I read charging over 14.9 can cause this. I am asking because while I was having some trial and error time with my Mechman 270 trying to get the AVBM set right I did occasionally over the course of a couple months, charge 15.0-15.1 while driving at highway speeds. I finally have it set to 14.9 on cold start up and after stop and go driving it settles down to 14.5-14.6 idle. I'm just really scared of ruining a 300 dollar battery. I didn't see any other thread on this particular subject so I figure it may help someone else in the future by knowing what to look for. Thank you all for any help.

kickass audio Posted February 12, 2012 Report Share Posted February 12, 2012 The vents for xs batteries are just underneath the label on the top of the battery. If they are venting they will start to push upwards and you will see a crack in the label on the battery. I highly doubt you have had this happen. Ive had my xs batts at over 15.4 when it was colder than 30 degrees outside. It stayed in that voltage for about 45 minutes of my drive and then went to 14.4 where it needed to be. Ive seen several people run at 15v flat with a 12v battery without any problems but it can shorten the life of your battery by doing so. I was thinking of getting an adjustable voltage module from mechman but as my truck never charges less than 14.45v i am just going to leave it as is.

They seem to be holding the charge fine still. Quote Link to comment Share on other sites More sharing options...

kickass audio Posted February 12, 2012 Report Share Posted February 12, 2012 dude just drop it. Its fine for where it is set now. My truck loves to be in the 14.9's to 15.4 when its cold but it goes to 14.45-14.66v once its warm. Its normal for alts to do this. There is no alternator on the market that does not change its voltage output with the temperature of the alternator.

Nathan @ XSpower Posted February 16, 2012 Report Share Posted February 16, 2012 Signs of venting is a sulfur smell and a liquid sometimes will be seen around the vents of the battery. If there is major venting it will usually come along with swelling of the batteries. Quote Link to comment Share on other sites More sharing options...
