Joe Gwinn You may notice that in battery explosions, the battery above the liquid level is gone, from the liquid level down the case is still there. When it happened to me, the two battery poles were still there. Started the truck and used it to drive to a water source to wash off the acid. As a side note, it was nearly as loud as a shotgun going off. |

If it was static overpressure, I would expect the top to pop off (busting at the seams). Are you saying that the sidewalls down to the liquid level also vanished? Joe Gwinn Yes. The acid (liquid) was up to the top of the existing case. In my case, my battery exploded because of my stupidity, there was no internal spark but an external one. Rick |

Battery on floor, bent over and connected charger. BOOM! Battery top missed my face by about 2 RCHs, hit the 12-ft ceiling above. Not even any acid on me. I was very lucky. I'm smarter now. |
