18650 Battery Heat Shrink Wrap

These high-quality PVC heat shrink wraps are specifically designed to re-wrap and protect 18650 lithium-ion batteries. When your battery’s original wrapper becomes damaged, torn, or worn, these replacement sleeves provide essential insulation to prevent short circuits and ensure safe operation. Made from durable PVC material that shrinks evenly when heated with a heat gun or hair dryer, creating a tight, protective seal around your battery. The proper insulation prevents accidental contact between the positive and negative terminals, which is critical for battery safety in flashlights, power banks, and DIY battery packs. Simple to apply even for beginners – just slide over the battery and apply gentle heat for professional results that restore your batteries to like-new condition.
