Protect your batteries from accidental short circuits with additional sheathing or replace damaged and porous sheathing. Only suitable for unprotected 18650 batteries. (max. length 65 mm)

10x Heat Shrink Tubing Cut to fit 70 mm for 18650 cells.

Many battery suppliers for daily use such as Efest, Keeppower, Enerpower etc. already provide their own batteries with a durable PVC shrink tubing to ensure safety in use. Since industrial batteries are built for further processing, the protective sheathing of the cells is not sufficient for daily applications. A damaged protective jacket can quickly become the undoing of Li-Ion batteries. (Short circuit, fire, explosion etc.).

Examples of use:

Replace damaged protective sheathing. Attach additional heat shrink tubing to increase safety (especially important for industrial cells). Replacement for already worn or torn down heat shrink tubing. Matching the heat shrink tubing - and also an important part of the protective sheathing - we have insulating rings for the positive pole made of HPVC. Item number: 401511

Processing:

Pull the heat shrink tubing over the cell so that the cell is in the centre of the heat shrink tubing. Using a heat gun or a suitable warm air dryer, first shrink the tubing at the positive pole and then at the negative pole. When the tubing has curved at both poles and is tight in view, the treatment is carried out on the outer surface of the cell.

Tips and safety:

Do not heat the shrink tubing and battery too much, because the shrink tubing starts to shrink at 80 °C already. Do not heat the cell for too long. Do not place the cell and shrink tubing in the oven or microwave. (Fire and explosion hazard)

Scope of delivery: 1 pack of 10x heat shrink tubing in the colour orange.
