Battery Backup
3 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 up to 24 hours 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. 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.

RED LED:

• A solid red LED with beep, sounding every 30 seconds, indicates the battery will no longer
