WOOHOO!! New Batteries!
Well, after 9 years of faithful service, and one too many times being allowed to boil dry, not to mention twice being run into the ground, the trailer's battery bank (4 Trojan T-105 6V batteries) fina...

Float spec is 13.5v at 25C, but here they also give the temp comp as 0.005v per 1 degree C. So at 5C /40F the PD at 13.6 would be right.
The 13.2 would be right for Death Valley in August I suppose. :(
Actually, I doubt 13.6 vs 13.5 at 25C is going to matter a whole lot for an RV that cycles the battery. I suppose it matters for a static situation such as never going off-grid.
EDIT. For charging there is voltage drop between charger and battery too, so accuracy in meeting the specs in an RV is not likely anyway IMO.

I see they say to keep above 60% SOC at freezing temps. So my habit of doing 50-90s in winter needs another look. Hmmmm.
