360 PCS 18650 Battery Sleeves Flat PVC Wrap Heat Shrink Tubing Tube(and 360 PCS Self-Adhesive Insulator Ring Cyan)

They worked perfectly ! Fantastic product and shrink nicely with a hair dryer on high heat.

Fantastic set of battery sleeves and insulators. They fit my a range of 18650s perfectly. They’re durable but not too thick.

It was my first time wrapping batteries, so it took a little bit of effort for me but nothing hard, they were a perfect fit an comes in a nice variety of colors (including one that is gold/brownish that I felt I love with). Do recommend, is great quality, assorted, have a lot of wraps, is a great value for the money. Also, it is thick enough, and shrinks nicely

Cut to the right size and worked without any problems

I have thrown out my fair share of batteries due to plastic wear and tear. My nitecore charger loves to eat the battery sleeves if im not being careful inserting. Finally can save a few bucks! It was an extremely simple repair. Just gently remove the old damaged plastics (razor blade worked well creating a small slit and pulling the old sleeve off) and insert the battery into a new tube. Its a relatively tight fit so the battery can actually suspend before you even need a heat gun. Leave the button top exposed slightly out of the sleeve so you can center the insulation ring and slide the battery into the tube and center the battery within the tube leaving about the same length of sleeving on each end. Then just take a hair dryer or heat gun to it and it folds around and shrinks up. Im sure other heat methods may work, but caution is highly advised against using anything such as a flame due to the volatile nature of batteries. Either way, used properly this is a fantastic product that took me appx 3-4 minutes to do the repair/ replacement of 2 batteries sleevings. Thank you RockDig as well as anyone whom has made it through and read this review/quick how to guide!

If you know 18650 batteries and the potential of dame or fire, then you know a good insulator and wrap are vital! I have never re-wrapped my batteries, but this was easy! Ist try went perfect! Get the battery in the wrap, use your index fingers to center battery in wrap, hold one end and heat with a heat gun at about a 6” distance and move the heat back and forth on that end. The end will automatically wrap around the end perfectly. Don’t forget to add an insulator first! Do the other side and your done. Took my about two minutes to di 4 batteries. I have enough wraps to last a lifetime now! Very happy with the kit!!!

Fits 18650 batteries nicely. Shrinks to wrinkle free fit in seconds with heat gun.

So easy to apply and always start with the negative end of the battery for safety ! Great value !, you have all you need for several pairs or single battery’s , there are videos on the diy on YouTube for all precautions . Comes with insulator for positive end. Perfect kit

Arrive on time, good quality heat shrink

*TLDR = lots of colours, nice fit, isolators are good, don’t put too much heat I’m using a lot of old dead laptop battery and tools battery pack to salvage the cells inside. Sometime when you tear them apart, you accidentally dent or tear the protective lining. Those cells don’t have the protective board on them so if you short them, it take about 10sec to light up and go up in flames. So this kit takes the cells and put them back to a more secure state until they are put back in another battery pack. If you heat them up with flame of a powerful heat gun, you risk to tear them. This ain’t no heat shrink over a wire, this is a thin lining. Go easy on the heat, it will shrink fast anyways

Fit perfect, case was broken but keeping due to need of covers

Product comes in a nice container and are easy to use.

Good lit in plastic box. Good variety of colours. Fit foe 18650 battery
