The thermal switch needs to be well secured and in direct contact with the side of the battery. Service tape is available as a
service part and is the recommended solution. As an alternate, a heavy duty “duct” styled tape can be used. If “duct” styled
tape is used, wrapping the tape completely around the battery with minimal overlap will provide the best adhesion.
