Charge the Battery
The battery charges when the garage door opener is plugged into a 120Vac electrical outlet that has power and
requires 24 hours to fully charge. A fully charged battery supplies 12Vdc to the garage door opener for one to two days
of normal operation during an electrical power outage. After the electrical power has been restored, the battery will
recharge within 24 hours. The battery will last approximately 1 to 2 years with normal usage. Instructions for
replacement are provided with the battery. To obtain maximum battery life and prevent damage, disconnect the battery
when the garage door opener is unplugged for an extended period of time, such as a summer or winter home.
NOTE:
When the garage door opener is in battery backup mode the garage door opener lights, Timer-to-Close, and
Remote Close features are unavailable.
In battery backup mode, the Automatic Garage Door Lock will unlock when the garage door is opened, and will remain
disabled until power is restored.
