When out looking for batteries, it would be a good idea to take along a voltmeter, at least and a good hydrometer may help in picking good ones.
Good idea. I do have a pocket DVM and I don't know why I didn't take it.
I started charging a pair of the "good" ones and they are sucking in 25 amps so I take that as good sign; the charging voltage is rising rather quickly so I take that as a bad sign. At a glance, I'm guessing that they are at about 50% of new capacity... So many batteries and I only have one desulfater!
