requires 24 hours to fully charge. A fully charged battery supplies 12Vdc to the garage door opener for up to 24
hours during an electrical power outage. After the electrical power has been restored, the battery will recharge

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.
