Sorry for any confusion. I seem to have posted my last post in the wrong thread.
I mentioned I had a battery fail and that I was doing it again for the customer.
My mistake was measuring the SG when the electrolyte was low in the cells.
When I replenished the cells to near the maximum line, the SG went from the green, to half way up the red.
... That's the batt which is now well into the green with the cells at about full. And it took four extra days of pulsing.
The pulser I used was probably averaging a current draw of 2 Amps and the pulse is around 10 - 15 Amps on the setting it is on (Max).
