Fascinating thread! My batteries do not "pop" or warp or overheat; but I have had similar charging problems over a year (overcharging, reverse cell, many of the same voltage numbers). But I have computer stuff that does not belong in the charging circuit- 4 computer power supplies (3 even charge- sometimes) and 1 start and rapid floor charger. But with dumb luck I got lots of miles. Just not worth repairing- the batteries were new in 2007 so when they go they GO!
