Simply remove your old battery wrap, making sure to save the round insulator on the the positive end. Then slide the battery into the new wrap, place the insulator on the positive end and apply heat with a heat gun or hair dryer until the wrap shrinks to the battery. If you use a heat gun, set the heating element to low.
