To my

Sulphur I believe.

Lead sulphate actually.

The voltage has to be applied in brief pulses to be effective. That
is the only thing that smacks of high technology in the whole device.

They do work but my preference is to get a battery charger thrown in
as part of the deal. There is no reason to desulphate continuously
that I'm aware of.

The rationale behind the device:

1) It is self contained, powered by the very battery that it is
desulfating. There is no need to have AC power available to run a
converter ("battery charger").

2) Continual desulfation stresses the electrode plates less than
allowing the lead sulphate to build up to a high level and then
subjecting the battery to the stress required to blow it off.

Otherwise it's sort of like saying, "There's no reason to live a
healthy lifestyle and keep my circulation in good shape, I can always
undergo an angioplasty...."


I believe the concept has merit. The manual for the sophisticated
inverter/converter/charger that was installed in our former RV had a
desulphate mode and the manual recommended doing it at least once a month
for house batteries that were run down often.
