Hi Eric,

I'm curious, what brand and model number charger do you use that offers
those 3 charging phases. I may be interested in selling them if I can find
a good product at a good price.

I sell the Xenotronix charges. They have proven extremely reliable and seem
to take good care of glider batteries. I think they are 2 stage (phase)
chargers.

I sold the BatteryMINDer desulphating chargers for a while, but they didn't
sell well. They are more expensive and it is unknown whether they really
make batteries last longer.

I sell the Power-Sonic batteries and have had good results and feedback on
them.

What does the group think about desulfautors? I've done some
searching and see lots of widely varying opinions (which I suspect
I'll get here as well).

I'm skeptical about their value, because the only place I've seen them
touted is by the people that sell them, and I've never seen a technical
manual from Powersonic, Yuasa, Panasonic, etc., for SLA batteries that
even mentions them, much less suggest them. Instead, the manuals and
battery datasheets always recommend three phase chargers as the best type
of charger. Approximately...

Phase 1: constant current until 14.5 volts is reached
Phase 2: constant voltage 14.5 until the charge current drops off to 2% of
amp-hour rating (e.g., 7 AH x 2% = 0.140 amps)
Phase 3: constant voltage at 13.7 volts

But, I'm not aware that they do any harm, either.
