circuit I built about 4 years ago to restore nearly dead AGM batteries but I
have not had any sophisticated method of verifying before and after
performance. I perform a constant current equalization with no voltage limit
and then leave the battery on the pulser for a few weeks. This works great
and I have restored and sold a few used AGM batteries that would have gone to
the recycler. Today our battery buyer just picked up another
15,400 lb. of batteries from us. Yep, they were mostly murdered! I
would like to be able to restore more of them.<o:p></o:p></span></p>
