Battery spark... safe?

[Imfallen_Angel]

Short version: the wrap was a bit torned as I was putting battery in my mod, ending up getting caught on it, getting the plastic ring bent and there was a small spark. A tiny bit of liquid came out, (smelled like nail polish remover), but I yanked it out right away.

I've re-wrapped the battery, the ring is back in place, but before I put it back on the charger or a mod, should I be weary that the battery might be bad now and a risk?

Yes absolutely dispose of this battery.

liquid came out of the battery?? It's wrecked - get rid of it...

Yes absolutely dispose of this battery.

ok.. will do.

It really didn't take much though, this is my first incident like this with a battery, and the spark was very quick.

sounds like it vented a bit... no longer any good...

Good on you to check things out before proceeding with that battery

Absolutely bin it

According to Mooch, ECF's local battery expert:

"-- Venting --
Venting is a purely physical process that releases excess pressure that forms inside a battery if it is discharged too quickly or charged at too high a voltage. Both of these situations cause excess gas to be created and that increases the pressure inside the battery.

Each battery has a pre-weakened area of metal underneath the top contact. At a certain pressure level the weakened metal splits open and allows the pressure to escape. The solvent for the battery's electrolyte often oozes or sprays out too. This can be a problem because not only is it toxic but venting typically happens at around 130°C-160°C, which means the liquid is very hot.

Venting can be a rather gentle event or it can be a pretty energetic spurting and spraying of gas and liquid. Be careful, that liquid is toxic and flammable! The battery does not burst and there are no sparks or flames. The amount of gas produced is relatively small and can usually be handled quite easily by the venting holes we see in mods.

Once a battery vents, even just a little, it is ruined and should never be used again."​
