Update with some possible application for RVers.
It is a Group 48 flooded, as it turns out. The problem I was facing was it showed ok on holding voltage and the battery shop monster wheeled load tester showed that it was "better than 100%" BUT, it showed all over the map as "Fair" with my hydrometer some almost in the Red, some almost in the Green, but all in the White somewhere.
This after bringing it to FUL at 14.8 and then several hours at 15.7 Equalize with the VEC1093DBD.
All my RV.Net training is to believe the SG, and never mind all that other confusing stuff. So I went ahead and got a brand new Flooded (but sealed--he doesn't sell any with caps) 48 and stuck it in.
It is possible there was nothing wrong with the battery I handed in as core, but I just didn't trust it with that bunch of SG readings. So that's what I did. YMMV.
BTW the one I got has that comical green light. I thought they dropped that years ago. It only shows for one cell out of the six.
Whatever. As a sealed battery no hydrometer, in the future, I can't get confused!
