Charge the Battery
The battery charges while the garage door opener is plugged into an electrical outlet. The battery
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. 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.
