12V 7Ah Integrated Battery Backup
The Liftmaster 8500W features an integrated battery backup system that uses a lead-acid battery. The 'beeping' is an intentional audible alert generated by the logic board to notify the user that the battery can no longer hold a sufficient charge or has developed high internal resistance. Replacing the battery restores the continuity of the backup power circuit and clears the audible error state.
