Good post, Im a long retired electrical engineer although lead acid batteries and chemical energy storage and all that lead n lead sulphate n acid stuff is actually more chemical then electrical or mechanical engineering as you well know,,,,,,,,,,

Anywho, the reaction of the lead n acid and lead sulpahte only yields one polarity as far as I know and regardless how his battery got discharged, EITHER from a load or a load caused by hooking it up backwards to a charger, I still believe he has a chance of reviving it by a correct polarity charge. Of course, once a battery is completely shot it can NOT be revived or recharged so if thats the case then it may NOT be possible to revive it BUTTTTTTTTTTTTTTTT I still see no problem with giving it a try cuz I dont see the chances of it "blowing up" any greater then the chances of any battery blowing up from charging cuz after all, even charging a good battery causes expolsive gases which a spark could ignite.

Any thoughts??????
