Sealed lead acid battery fire?


New Member
Hello Electro-Tech community,
I had a small fire occur within a pile of 8 old emergency lights that had the lead acid batteries still inside each one. The lights had been removed from the wall earlier in the day. Terminals were NOT touching one another - batteries were just kept connected inside each fixture. Any thoughts on why there would be a short and/or combustion development?

If you're sure it was an electrical fire then something shorted. Look for signs of molten metal to work out how.

My guess would be one was dropped and the internal structure of a battery body was damaged, allowing an internal short.
