Testing AGM batteries?
When I got my last set of batteries (150aH AGM, used), they had been tested on a high-amp car tester. But my friend who knows batteries pretty well said that was not a proper test, that what we shoul...

Hey Don,
I'm rather a neophyte with VRLA construction but I would think the recombinant gas mechanism would reduce the need for a lot of gassing, irrespective of SG. I might be totally wrong about that?
The Genesis EP AGM's I'm using describe a "reconditioning" process should the batteries lose capacity. IIRC, the voltage is set at 16V for a period of time and there is no admonition about temperature. That's not a real healthy diet IMO. as boiling out any electrolyte would be bad AFAIK.
FWIW, my 6 V bank has the temp compensation connected from the solar controller and that pair is fairing very well. I just recently added water to the cells after a year of nearly constant charging. My controller is set to go into 14.6 bulk for a short period and then floats for the rest of the day if voltages stay above 13.5 V. The SG remains at a baseline 1.30 while in storage.
