Dropped my 18650 battery!

[tenacious]

Hi Guys,

So yesterday one of the 18650's slipped out of my hand. It dropped from a meter high. Would my battery still be ok? I cant seem to find any dents or serious damage on the shrink foil. (check pictures) Can i still keep using it and recharge, should i rewrap, or buy a new one?

Also can anyone please explain to me what the dangers are of having a damaged battery wrap in a regulated device like the cuboid? The last thing i want is battery venting.

Regards,
Tenacious

The battery looks fine. Just a slight scuff on the wrapper.

I wouldn't worry.

That said I'm viewing a photo on a small screened phone.

If there is a tear in the wrapper where any metal is exposed then it will need re-wrapping.

You're better placed to judge this than me.

What battery is that? Have you re-wrapped it previously, as it hasn't the manufacture markings of any quality battery I'm aware of.

I've dropped plenty of batteries and haven't had any resulting problems with any of them. The tore wrapper should be rewrapped, but in your cuboid it should be fine to use, as the plastic sled won't conduct anything. Rewraps are very cheap and easy to do, and are definitely a good idea!

In a pinch you can sometimes use a small piece of electrical tape to cover a tear until you can get shrinkwrap for rewrapping.

That doesn't look too bad to me, or at least from what I can see in the photos. If the battery can is dented, I'd discharge and recycle. If the wrap is damaged so metal is showing, I'd rewrap.

Vape it like you stole it.

That battery looks fine.

I drop mine all time. I would keep using it. I keep lots of rewrappers around for when needed. I rewrapped a friends batteries and told him they were new. He phoned me a couple days later telling me how good the new batteries were and how much longer they lasted over his old ones. Then I broke the news to him they are his batteries. LOL Cheers!

It's an LG HG2 i think the black code is under the white label or sticker. But im not sure, i ask my retailer. I expect them to be 100% genuine.

It does look like an HG2 chocolate from what I can see. If so, those are good 20A cells.

Kudos to you for asking this question.
It shows that you have your mind on safety and that's where all vapers' minds should be.
To me, someone who's dropped more batteries than a little bit, that looks like nothing more than a scuff mark. Totally safe to use and charge.
However, if that scuff turns into a tear and there is bare battery exposed, re-wrap.
And as always...Vape On!

Helps to actually be able to recognize levels of damage and know a bit about testing.

It Looks fine...................though any internal compression would not be visible.

A cycle of Drain on a Regulated mod at a lower wattage and normal Charge to full power would make me feel more confident in continuing use.

* I drop/knock over batteries often(disability issue) but rarely more than 2ft. to a decent carpet floor.

OK guys thanks so much help on here is great everyone is so supportive.

I don't know, that looks kinda sketchy to me. Might blow up in your face! No seriously I'm too new to say. I'm learning all I can about battery safety which is what brought me to your thread. At least you asked.
