My understanding is that sometimes, you can recharge the batteries
after hooking them up to a certain kind of charger that reconditions
them.  I don't think they end up good as new, however.

I think there is a "battery desulphater" charger that basically varies
the voltage to the battery in such a way that sulphur buildup on the
lead plates get zapped, allowing the battery to once again hold a
charge.  However, IANAEE .
