"Desulfator" is usually marketing doubletalk. All it means is that the charger
can apply a higher-than-usual voltage at lower-than-usual current to a very
dead battery. The doubletalk will make a big deal about their secret
proprietary pulsed charging algorithms. But, most plain old dumb car battery
charger consists of nothing but a transformer and rectifier; they inevitably
deliver over 16v of pulsed charging current into a completely dead battery.
If you don't let your batteries run too dead, you'll never need to "desulfate"
them anyway. If you *do* run them that dead, nothing is going to recover more
than a fraction of their original capacity anyway. It's cheaper to buy a new
battery than pay for some expensive "desulfator". These things are sold mainly
for car batteries, where even 1% of their original amphour capacity is still
enough to start the car (3 seconds at 300 amps is only 0.25 amphour).
I have a couple of EV lawnmowers. The chargers that came with them were junk
(battery killers). I use individual 12v chargers (Ault brand), built for
electric wheelchairs. The 3 batteries in one are all still good, and the 2 in
the Robomower are now over 10 years old.
