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.
