I did something stupid

[trojansteel]

I have two Nukes. I had been storing one in the nuke charger, unplugged. It stated in there for several months. When I went to swap the batteries, the nuke had exploded in the charger.

Was I not supposed to store a nuke in the charger???



Anyone know if Guy is ok? I sent him a couple a couple emails over the last few weeks and haven't heard back.

He had typically been very responsive.

Could you tell us a little about the storage environment ? .... Ambient temperature (max / min) and humidity ? Are you in a marine climate ? Any chance it could have gotten wet ?

I never store any batteries on the charger. I read that was bad to do somewhere along time ago here. Search battery charging and storing here. Tons of threads.

Because chargers sense the voltage of batteries as they charge, it means there is current consumption on the cells when if the charger is in the off state. high enough for long enough and cells will drain out. If the cell has no overdischarge protection the cell voltage will sag beyond the safe limit and cause issues, explosion is quite rare but internal chemistry might be so far off that its not possible to recover a cell.

Was kept in a drawer next to my bed. House is quite dry.

I guess that's what happened! Didn't think there would be an issue if it the charger wasn't plugged in.

Never store any battery plugged into any device, ever. None of such devices physically break the circuit on power off, which means the battery will slowly discharge even if not actively used.

This is also why I'm a wee bit leery on flashlights with built in chargers..... and cells with built in chargers

I believe the postpartum damage of this total discharge was caused by leaking hydrofluoric acid.
The vent on the top of the battery and entire case of the cell still look OK in the picture.
