Torn Wrapper - Is it still usable?

[00gt1]

Ok so I have an ultrafire 18650 3000mah. I noticed the other day a TINY... and I mean TINY tear in the wrapper. Do you feel that it would be safe to still use? Is there a way to repair a tiny tear (maybe electrical tape)? I really don't want to get rid of it, it's a nice backup battery but safety always comes first!!

It will only get worst = dangerous. Re-wrap!

Either tape the tear with your favorite thin tape.. (yes, a bit of scotch tape will do fine for a small tear...) or re-wrap the battery.

IMO the cost of the roll outweighs the cost of future batteries. I have re-wrapped several batteries. I bought my roll 2 yrs ago. To me it was a no brainer.

Thanks everyone I will be rewrapping it. Is there any special method to doing it or is it just like using any other heat shrink?

I came across this tutorial of how to re-wrap batteries when I was looking at battery and charger reviews a while back. I think it's good, but I have not done it yet. Switched, please have a look if you could and let us know what you think. I'm interested too because I have a battery that I'm also thinking should be done before it gets worse.

BTW, that site has great battery and charger reviews. He gets right into it!

A heat gun is an asset no denying that, but verniers? I never used them I come from the days of a ruler or scale in my field LOL. Nonetheless the info is correct.

Don't have a heat gun? Borrow your wife's = hair dryer

Your welcome good buddy.

Glad to see the OP heeding our advice. It frustrates me to no avail to see folks spend hundreds of dollars on mods, yet skimp on the basics, like proper battery maintenance. Think of it as doing an oil change on your car Look after your gear and it will look after you, just like your engine
