Look at the illustration above. Note that the battery slides UNDER the aluminum “bridge”, “clip” or “bracket”. DO NOT place it on top. Be sure the plus (+) side is up. Incorrect insertion will burn out the circuit or break the solder connection.
The cover should only be finger tight (snug) so as to remain waterproof. Please, DO NOT use pliers and a pipe wrench! Over tightening will damage the O-ring. Obvious signs of abuse (pliers or rubbing marks) will void the warranty.
