Battery explosion
I have a 2003 Newmar Dutch Star and had a deep cycle battery explode last Saturday. I am looking for some thoughts or ideas of what may have been the cause. I was starting the engine and released ...

You posted that the battery was a deep cycle battery, I assume that it is a house battery. The real question is, why would a house battery explode when starting the engine? The house battery is not used to start the engine unless the boost switch is used. You may have additional problems. JT
Just guessing, but the alternator on the engine will charge the house batteries along with the chassis batteries. I'm thinking that is part of the puzzle.

When you have any type electrolyte battery(sealed or deep cycle) that either is boiled and the plates exposed or dry and you put a charge current to it. THAT charge current is enough to ignite the excess gas in the battery and blow it up. When it exploded, did you have a gallon of battery acid all over the place? I will bet NOT, since the battery was dry or almost dry and you saw minimal fluid. Also, a loose connection at the battery bank (neg or Pos) will also cause a spark when a load is applied. Doug
