Tenergy NiMHs are pretty tough batteries.

Wow !

I think I speak for everyone here in expressing relief that nothing serious happened.

My testing setup involves tabs on the end of the cells (2 AA alkaline in series) that need a magnet to compress them and complete the circuit. When not in use, the magnets are an arm’s length away.

That puddle ’o plastic would have been quite a sight to see, however…

A photo or diagram of your setup would be appreciated. I need a visual to comprehend these things.
