No, the battery didn't blow up, but it took out my regulator... But that turned out to be a good thing, because in trying to fix the damage, I found out my generator's bearings and bushings were really bad, and would have surely left me stranded on the side of the road on a longer trip. God works in mysterious ways, sometimes. I did have a battery blow up in my face during another incident, though. I was young (16), stupid and frustrated. Fortunately no physical damage to my face or eyes. (They say experience comes from doing stupid things, which means I've got a lot of experience under my belt )
