Rated voltage:300V Temperature range:-55C to + 105C Shrinking rate: 48%(cross section)and 8%(longitudinal) Feature:Flame retardant, insulation, soft, stable performance, low temperature shrinkage, shrinking fast, etc. Can have the effect of anti-counterfeiting and beautify the packing materials, and the items were capsuled can have insulation, moistureproof, , the effect of dustproof, etc. :used for 1xAA Battery. Notice: To find the size you need, measure the cross-section circumference of your pack and then divide it by 2 .Use the shrink wrap size at least 5 mm (1/5 inch) than your half circumference value. 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 your pack. When heating it, the temperature will increase in few seconds. In such short time, the heat will not transmit to the battery.
