Will these wraps fit my specific rechargeable batteries?

Yes, these precut wraps are designed specifically for 18650, 21700, and 26650 lithium-ion batteries. They match the flat widths of these common cells, from 29.5 mm up to 43 mm. Just make sure to select the correct size option for your battery model before purchasing.

What is the best way to apply these heat shrink wraps to my batteries?

Slide the precut sleeve over your battery and apply heat using a heat gun or hair dryer. The PVC material begins shrinking at 80°C and reaches a full shrink at 120°C. Rotate the battery evenly during heating to get a tight, snug fit without overheating the cell.

How do these wraps help protect my battery packs from short-circuiting?

Damaged battery insulation is dangerous, but these PVC sleeves restore a safe, non-conductive barrier around your cells. With a high dielectric strength of 20 kV/mm or more, they block electricity from jumping between cells. They also have a VW-1 flammability rating to provide extra protection against fire hazards.

A: The primary function of this PVC heat shrink wrap is to provide an insulating and protective outer layer for cylindrical lithium-ion batteries. It helps to prevent short circuits, physical damage, and wear on the battery's original casing.. Q: How is the heat shrink wrap applied to a battery? A: The heat shrink wrap is applied by sliding a precut sleeve over the battery. Heat is then uniformly applied using a heat gun or hairdryer, causing the PVC material to shrink tightly around the battery's contours, forming a secure and insulated covering.. Q: Is this heat shrink wrap suitable for all battery types? A: No, this heat shrink wrap is specifically designed and precut for 18650, 21700, and 26650 size cylindrical batteries. Using it on other battery sizes may result in an improper fit or insufficient protection.. Q: Does the wrap provide electrical insulation? A: Yes, the PVC material of the heat shrink wrap provides electrical insulation. It helps to prevent accidental contact between the battery's conductive surfaces and external objects, enhancing safety during handling and use.. Q: Can this product be reused after being shrunk onto a battery? A: No, once the heat shrink wrap has been applied and shrunk onto a battery, it is not designed for reuse. To remove it, the wrap must be carefully cut, and a new sleeve should be used for subsequent re-wrapping..
