Battery Wraps - 18650 Assorted

18650 Battery Wraps are precut, heat-shrinkable PVC sleeves designed to replace damaged, torn, or worn plastic insulation on standard 18650 rechargeable batteries.

Maintaining an intact outer sleeve is essential for battery safety: because the entire metal casing of an 18650 cell acts as the negative terminal, any tear in the outer insulation creates a severe risk of direct short-circuiting against metal battery housings or contact points.

Key Features:

• Safety & Protection: Prevents short circuits, arching, and accidental battery failure.
• Easy Application: Slides directly over the battery cell and shrinks tightly when brief heat is applied (using a hair dryer or heat gun).
• Pre-Cut Fit: Sized specifically to fit standard 18650 lithium-ion cells.
• Custom Styles: Available in clear, solid colors, and unique graphic designs for quick battery identification and personalization.
