At what point does a peeling 18650 battery wrap become unsafe? Some of mine are starting to peel back where it wraps at the base. Thanks!

I look at it as a better safe than sorry situation. If my wrap has as much as just a small nick in it, I peel and replace it with a new one. Until I started vaping I never knew that the housing of a lithium-ion battery was its negative post. Once I understood that, I understood why it's important to keep your wraps in good shape.
Very quickly. I agree with @asharru. Once the body of the cell gets uncovered at all, it's time to rewrap.
Rewrapping is easy and wraps & insulators are cheap.
Just get some Molicell P26A batteries and you probably won't have the problem.
(quick bet) you are using Samsung 25R cells. And, they are "thin skinned".

Thermal runaway, exploding batteries, takes place when the the nipple of the positive end is bridged to the outer casing of the battery. This can happen from a small piece of metal in your pocket, a key, or small, loose debris. You're an adult so be safe and keep your gear clean. Re-wrapping takes a few minutes and could prevent injury.
If youre asking the question then it’s already too late. Do Not Use until it gets rewrapped or properly disposed of!!!
I would rewrap the battery. It's a super easy and quick task. No need to "retire" it for a peeling wrap. Wraps and insulators should be in every vapers kit. Common sense.
im relieved!! Those little batteries can cause some nasty injuries or worse!
Not just because of the damaged wrap. It was 5 years old, and not holding a charge like it used too. Replacing it was a better personal choice to me than rewrapping it.
Seriously?
How much does a pack of smokes currently cost where you live?
How much does a new battery cost?
I'd say its time to toss it and buy a new one.

I use a MiBoxer C4 charger that shows internal resistance in the display. I don't necessarily trash a cell unless vape time is noticeable lower than other cells. 400 milliohms would be a good indicator that the cell needs to be replaced according to most sources I've read.
I rotate 8 18650's in my ecigs and flashlights and those have been working well for over two years. Vaping at 10 watts makes my cells last for years. I still have some 18650's that developed higher resistance. I use those in my LED flashlights and still get good service from them around the house.
