Battery ....RIP,......... Death By Polar Vortex??

….Pry the caps off and see if the cells are dry. Sounds like overcharging to me...…………..
Well, I hope it hasn't boiled out already, lol. I've already exchanged it for the new one (see 1st post). The old one showed no signs of any regurgitating or tell tale on the painted hood just above it. The battery insulation wrap is a little dusty but no wet spots at all.
It has the whopping 3 month replace warranty so I'll have Advance check it just prior to the OOW date. I think I'll have the alternator tested at another store in the meantime.
