What does the group think about desulfautors? *I've done some

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.
