I went on a run today and had some problems. I had some crappy connections on my Battery and during a hard climb stalled the engine. Tried to restart the engine, and "Click Click" - Bad Connection. Had someone "Jiggle the cables" and during one of the turn key's, the battery exploded. Unfortunate thing was a friend was helping and he took the brunt of the explosion in the face. We quickly doused him with water and luckily he is fine. He didn't get any in the eyes, just on his skin and carhart jacket. I am pretty sure the carhart will disentegrate someday soon, lets just hope his skin doesn't! It appears, the battery connection sparked during this scenerio and caused the gasses insided the battery to ignite. The battery exploded louder than a shotgun blast! It completely devistated the battery. Just thought I would pass on this info - don't want this to happen to anyone else. A $4.00 pair of new terminals would have fixed this problem. If you have corrosion, think about this scenerio. We had to winch me up a rock ledge. Nobody had jumpers so I borrowed a battery to get me started. On the way out of the trail, I caved in my bedside. Bad Carma I guess. I believe someone took pics, I will post them If I get copies.
