I had two Odyssey batteries self destruct from bad cells. I won't ever touch those again. When I mean self destruct I mean CAUGHT ON FRICKEN FIRE. The first one shorted out internally and started melting/burning while inside my mustang. By some miracle I was in the garage working on my lawn mower when I heard a little pop/sizzle. I was already working on the mustang and the battery was unhooked. I used my big ass Channel locks and put it in the middle of my driveway. It continued to melt/pop and smoke. Finally it finished. This.... was a replacement that was only a month old after my first one did the same thing completely unhooked sitting on the ground next to my work bench. I was using the smaller PC680.
I just replaced my SHO's motorcraft MAX Monday. The one in there was from 15'. I think a cell went dead because it was fine the night before, then no juice and I couldn't get it to charge back up. Love that MAX warranty.
