Re: [RE-wrenches] battery venting re VRLA

[Allan Sindelar]

In reference to William's comment about equalizing VRLA batteries, see page 17 of Concorde Battery's SunXtender technical manual, available online at http://www.sunxtender.com/pdfs/Sun_Xtender_Battery_Technical_Manual.pdf. They instruct charging these AGM VRLA batteries at C/24 until 2.60 VPC is achieved, plus 4 hours, to recover from deep discharge, adding that this process can take 16 to 20 hours.

I have also heard in the distant past and then read recently on a manufacturer's web site that VRLA batteries can and should be equalized.  The parameters are different from an FLA battery.
