[AT] AT -Battery desulfator

[Spencer Yost]

Schumacher makes a desulfanator/charger that has saved several batteries. It actually was a gift to my son about 20 years ago (I love giving gifts that I can borrow :-) ). But when he moved to Raleigh it went with him so I don’t have it nearby to look at model numbers or anything.  I remember the price being on the high-end of the Schumacher line. A quick search of current models does not turn up anything that is exactly like the one I bought.

And I use a 50-year-old Schumacher charger that will charge completely dead batteries, unlike the modern electronic "smart" chargers that won't turn on if hooked to a totally discharged battery.
