Absorption Voltage question.
I have 4 Interstate 6v GC2-XHD-UTL house batteries, two series strings in parallel. Setting up the Midnight Solar 200 Classic Light and I think the Absorption rate appears to be on the high side. ...

This comes up from time to time. Interstate wrongly gave that high voltage for the Vabs when they really meant it for the "finish" stage in a particular charging profile (third one down at bottom of this)

So for "normal" charging like the two- step one in the middle graph, use 14.8v for your Vabs and you will be fine. Only use the 15+ voltage step occasionally to do the recommended "overcharge." Keep an eye on your SG with an hydrometer to tell when you need one of those overcharge sessions. (also makes you look at your "water" level, which is a good thing)
Dang BFL13 you put it sooooo much nicer then i did. :B
