[AT] 6V chargers - repost

[dglass]

I don't know.  When it is desulfating, the charge light blinks and 
different voltages flash on the dial. It doesn't say if it is positive 
or negative, but if I had to guess I would say it stays the same 
polarity and just pulses the voltage. I read that this technology has 
been around in industrial chargers but just came affordable for home use.
