Speaking of sulfated batteries, I've had really good
luck with these high frequency pulse chargers and have
been able to "revive" several batteries I thought were
ruined.

There are several subsequent patents on this technique and
various implementations, but an earlry one, if not the orginal
one, was patent #5,491,399, Gregory et al.

I found a Pulsetech model at a local Batterys Plus retail store.
They have both transformer and solar panel powered versions.

Works great for long term maintenance of the battery.

I have a neighbor who is also "off-grid" and used one of these pulse
chargers on his battery bank. He had good results, too.
