Take Lee Hart's advice on battery maintainance, he's right on the money.
On the subject of de-sulfating, there was a schematic and plan for a pulse
type de-sulfator in one of the electronics mags several years ago (15
maybe). It used a solid DC charge with periodic interruption by a high
reverse voltage pulse. Supposed to work but I didn't try and build one.
Maybe it's not a good thing, but I have helped some batteries by completely
discharging, reverse charging for a short time, discharging again and then
charging normally. This sometimes helps on one that is completely
Also, I have a Black & Decker walk behind battery powered reel mower, has
anyone heard of this, it seems to like 24 VDC to operate. Had no batteries
or charger when I found it.
