One battery seems to be coming around.
The other one has one cell "smoking" pretty good at 20 amps. This one did have some exposed plates prior to refilling.
When I rejuvenated a few old batteries that came from my dad's rig and sat quite a while one came up after charging with a trickle for a few days-the second I charged at a high rate and then rested and then low and then rested and then I think I let it sit for a day or 2 and then trickled it until it finally came back up-all said and done one of the batteries recovered pretty good-the other would hold 12.5 or so but not much more. As mentioned above both leaked some because I put too much water in to start.
I'd let your 'smoking' battery sit for a bit with no charger-and also suggest getting hold of a trickle charger and using that next.
