I had this wierd event with my EX1 Gates housing & Greenforce new FIII batteries last month during our new documentary shootings.

After the dive, I left the housing in a shady area to dry a bit, rinsed off its fresh water on it. While eating my lunch i heard a heavy explosion sound and a lady running away.
I was thinking please not the housing, but yes there it was one of the batteries exploded spilling the battery fluid outside breaking the outer part of the battery. luckily nobody get hurt or it didnt explode while I was working on it.

Checking it the night before, there was no signs of water getting in, broken part or corrosive elements.

We send the battery and the light to greenforce for an investigation, there is no word yet but hopefully soon i will get my batteries and continue soon.

cheers,

Well Mert, you were lucky it didn't leak when you were underwater!

Well polyacetals have high heat resistance. I assume that's what the Greenforce battery pack is made of. In all likelihood, there was a leak in the wiring that led to the batteries reacting to salt water. Modern battery packs are sealed inside their wrap for double protection... or at least they should be. If this were a lithium battery, it would've been more fireworks! :D

Scary stuff, though at least you didn't burn down a hotel room or 4x4 like some others.
