Frequently Asked Questions

Q: What size 18650 batteries does this PVC heat shrink tubing fit?

A: This kit includes two flat sizes — 30×72mm and 50×75mm — designed to fit standard 18650 lithium battery cells. The ≥48% shrinkage rate ensures a snug, secure wrap around the cell body for a clean, finished look.

Q: What temperature is needed to shrink the PVC battery wrap tubing?

A: The PVC heat shrink tubing activates at a low shrinking temperature of 80°C. A standard heat gun works perfectly. The material also withstands operating temperatures ranging from -40°C to 105°C once applied.

Q: Can this battery wrap be used on components other than 18650 cells?

A: Absolutely! These PVC heat shrink sleeves are widely used on electrolytic capacitors, lithium battery packs, LED pins, electronic components, and general combination packaging — anywhere you need insulation, moisture resistance, or a tidy coated appearance.

Q: How many pieces come in the kit and what colors are available?

A: Each kit contains 100 pieces of flat PVC heat shrink tubing. You can choose from Blue or Green in two size variants (A and B), making this an ideal assorted kit for DIY electronics builds and battery pack restorations.
