18650 Battery Wrap Wear

[Katcandoo]

Question: Some of my 18650s are starting to show wear on the wrapping. A nick here or there, minor peeling on the ends. At what point are they unsafe? I use regulated box mods. Voopoo, Ileaf, joyetech Espion. Thanks!

Re-wrap them. Wraps are dirt cheap, free in some cases when purchasing new cells. Don’t risk any potential mishaps, just re-wrap.

Yep. Hit up fasttech.com

A quick fix for nicks is electrical tape.

As a general rule if you can see metal anywhere else than where you could when the cell was new it’s time to rewrap.

Just what Punk & Bomb said.
Even in regulated mods cells can and will short out when any part of the metal cans touch each other directly.
No chipset can prevent that.

Apart from the raised nipple at the top, the entire casing is the negative terminal. Even a tiny tear can be potentially dangerous. See the link below for instructions on how to rewrap and links to wrap suppliers.

As mentioned wraps are very inexpensive – good idea to purchase a surplus of them so you always have spares on hand. Also, a good idea to purchase a surplus of insulator rings for the positive side of the cell in the event they become damaged as well. Again, very cheap.

On Mooch’s recommended battery tables there is a list of battery vendors that sell both wraps and insulators. Or if you have any vape retail outlets local to you, inquire.

Battery Mooch says keep the wraps in pristene like-new condition. It they aren't, stop using them and rewrap them or buy new batteries.

If you want to mark your cells with additional info like pairing and date for example, it might even be a good idea to double wrap them with a second clear wrap. If it's not too tight a fit in your mod, that is.

Oh. And speaking of cute...
