Battery Porfile

That's what I was looking for.

Thanks

from a JCI doc 2004 - Marine DC batteries

click on 'marine batt charging' tab at bottom
Should bulk recharge very shortly after discharge.
14.4-14.8v Absorption Charge
12.9-13.1V Float
16.0-16.3V Equalization Charge
sg 1.265 - 1.305 at end of equalization charge and throughout float. If battery is not floated specific gravity will slowly decrease after equalization charge due to self discharge.
If no float, may need to equalize charge every few months when OCV drops to 12.4.

does not mention temp correction but sure it is needed in extremes.

I'd get solar to use to maintain with a controller that has similar or programable set pts.
