According to GPL-31XT specs I found online : Bulk Charge Voltages: 14.20 - 14.60 Absorbtion Charge Voltages: 14.20 - 14.60 East Penn recommends a lower voltage, 14.0 volts at 70-80 deg F, for charging their gel batteries. http://www.evdl.org/docs/deka-vrr.pdf Personally, I think that's a bit low. I've used 14.3v with the Dominators in my GE Elec-trak tractor for over 10 years and they're still serving well, though I haven't done any capacity tests lately. However, if Delta-Q is following East Penn's docs to the letter, your charger may undercharge your AGMs. Long-term, that would lead to sulfation and thus reduced capacity. I suggest you charge them while monitoring on- charge voltage, and make sure that it reaches at least 14.2 volts per module while on charge. One of Delta-Q's designers, Roger Stockton, is on this list. He can probably tell you more about profiles for your charger and how to change them (if it's possible). Over to you, Roger. ;-) David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
