uxcell 10Meters 64mm Width PVC Heat Shrink Wrap Yellow for AA Battery Pack

• PVC Heat Shrink Tubing is a thin-wall, low cost material offering good electrical and mechanical characteristics. When exposed to heat in excess of 98 degree for a few seconds, the specially formulated polyvinyl chloride material will shrink rapidly and uniformly conforming to the shape of the object to be covered.
• Applications include insulation and jacketing of batteries, capacitors and similar objects-a vast range of applications in the production of industrial equipment, toys, sporting goods, electronics, and consumer products.

Q and A: Q:Does heat-shrink wrap make batteries hotter?
A:The shrink is simply a cover to keep you from catching the edges of the cells on something in/on/around the plane and destroying your pack. When heating it, the temperature will increase in few seconds. In such short time, the heat will not transmit to the battery.

Q: Do I use the rubber one to replace it:
A:No. Rubber-made shrink wrap is too thick for batteries and there is no much space for the battery wrapped by rubber shrink tube. These batteries can not take the high melt point of rubber. PVC is perfect material for wrapping your battery.
