For you cheap lead bastards out there, sciplus has some surplus 12v 10ah batteries in.
At about 10Wh per dollar... did I do the math right? And of course at the typical EV discharge rate its more like half that.
And ross still has the Currie surplus tabless 12-7 batteries for $76 shipped per eight. Come with wire leads. Fuses no extra charge.
Update! Sciplus fullriver 12v 10ah bat DOA. They said they going to send out a replacement after they test it to make sure its alive.
Update2, I left it on a dumb charger for a couple days and its up to like 10 volts now. The smart charger wouldn't do anything to it, just gave me the red light. I think it has a bad cell or two inside. Maybe I can use it for a 9-10v booster pack or something. I'll try the tecmate desulfater next to see if the bad cells can be recovered. If that don't work I'll try 'pulsing' it with my 36v charger to see if that can fix it.
Update3, Dumb charger now has it up at 12.8v resting, only a tenth or two off what my healthy batteries show. Not sure if it will supply a decent amount of amp hours though.
