i have 3 cats, all are beasts, all have awesome personalities, I keep NO light on ANY shelf. Ever. I keep all my lights either on display with batteries or in my drawer with batteries, all I look at/check every day and the cats couldn't touch if they wanted to. Believe me, they want to lol. Then again my collection isn't hundreds of lights. It's tens of lights..

Lightbringer, I want to remind you that Li Ion battery electrolyte contains hydrofluoric acid.
It has excellent absorbtion by skin contact and won’t cause pain.
But it will start eating your bones (calcium).
Of course, quantity and length of exposure play a big role in how severe it is but you’d rather read up on it or talk to a doctor, it’s scary stuff.
IIRC the “antidote” is just big quanities of supplemental calcium so the acid eats that instead of your bones.
Hope you’re well!
Likely it’s already out of your body but it might be worth looking into.

That is terrifying information, but thank you for it

Looks like your battery at 3.6 volts just had enough energy for the warm fuzzies instead of the loud KaBoom.

No worries. I buy milk by the gallon jugs. LOL

And now I fully understand Marvin’s pain.

Yabbut, what made it fizz to begin with?

No physical damage anywhere, no dents, dings, split-wraps, nothing of the kind.

That’s what surprised me, that “out of nowhere” it could just hæmorrhage its innards inside the light for no reason.

This can be true, but only after exposure to water (moisture in the air counts)

Important thing for folks to know. This is an exceedingly rare event that Li-ions will leak without more catastrophic failure, but in the case that it does happen, clean up should be taken extremely cautiously. HF is a serious bastard.

First and foremost is skin PPE. Double nitrile gloves.

Use dry absorbents for bulk cleanup. Double or triple bag the contaminated waste products.

If and when you need to use water for cleanup, use COLD water. Hot water plus organic LiPF6 based electrolyte is a guarantee to form at least some amount of HF. Below room temp water OTOH is fairly safe.
