I'm curious also as 'normal' batteries can be resurrected (sometimes) even after a long period of disuse.

Andy replies,
It depends on how bad the plates have sulfated. If you google the term "battery desulfator", you will learn about special battery chargers that use a pulsing high frequency charge to dissipate sulfate on the plates, and if the battery isn't too far gone, will restore it somewhat. These are not miracle devices, tho, and , in general, greatly lengthen the life of a lead acid battery PROVIDING it is being "nursed". It probably won't do your "ressurection", but is an interesting subject to learn about for future reference.
