LDCO800 Garage Door Opener
MODEL BBU BATTERY BACKUP UNIT
User’s Guide
Your Model LDCO800 Garage Door Opener is specially 
equipped with Linear’s Model BBU Battery Backup Unit.
In the case of an AC power failure, the Battery Backup Unit 
will power your garage door opener for up to 24 hours without 
AC power. The length of time that the Battery Backup Unit 
will power the opener depends on the number of open/close 
cycles performed while the opener is on battery backup power.
Note that the opener’s courtesy lamp will not light while the 
opener is operating on battery backup power.
When the AC power returns, the Battery Backup Unit will 
automatically charge its batteries. Allow 48 hours for a 
complete battery recharge.
The Backup Battery Unit regularly performs a self-check 
routine. If the self-check detects that the batteries are no 
longer serviceable, the three beeps will sound from inside 
the opener every minute. If this occurs, call your garage door 
installation professional for a replacement Battery Backup Unit.
