Description
Each piece is a heat-shrink sleeve that you use to rewrap lithium-ion batteries when their original insulation gets damaged, scratched, or peeled off. The wraps provide both safety (preventing short circuits) and a chance for customization with different colors. How it works: Remove the old damaged wrap.
Slide the new sleeve over the battery (don’t forget the insulating ring on the positive side).
Use a heat gun or hair dryer to shrink it tightly around the cell.
