Battery Status LED

CHARGE THE BATTERY

The battery will take 24 hours to fully charge. A fully charged battery supplies 12 Vdc to the garage door opener for one to two days of normal operation during an electrical power outage.
Once the battery voltage drops too low, the battery will no longer operate. After the electrical power has been restored, the battery will recharge within 24 hours. The battery will last 3 to 5
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.

NOTE: Door operation may be limited until the battery is fully charged. The garage door opener lights will not turn on during battery backup mode.
