Lead Acid Battery - 2 Cells No Float
So I picked up a new (to me) rig from family last weekend. It had been sitting at the BIL's place for several years. He started it occasionally, but never kept it plugged in. 2 of the 3 group 29,...

If amps tapered down to 6 and then started to climb, that could mean amps are going to heat. You could have some excitement! :(
If that happens with AGMs that get down to full and then amps start back up, it is all heat rising in a sealed batt, so you must stop!
With that batt, IMO just stop fooling with it and take the core rebate.
Speaking of AGMs, in one of my set-ups, I decided it was safe to use them inside as long as I didn't over-charge them, so that gave me lots of choices where batts could go.
Sure! You can hang AGMs upside down and sideways if need be.
Now in the past, I've had situations where the current began to climb and it meant I was making progress. I love a good challenge and relish the subsequent victory, but I'm glad I "asked." I should've thought of that. It's clear I've been out of the game too long.
I went and shot it with my infrared gun. Saw the current pumping in was now 15.5. It's now 55F out and the exterior of the battery was at 113!!! The electrolyte must be quite a bit hotter. And the area of the 2 neighboring low cells were noticeably cooler. So all that power was likely going to four... already fully charged... and now WELL equalized... cells.
Thank God it's not a hot, summer night!
Core it is! I'm headed to Wally tomorrow to pick up some oil anyway.
Thanks!
