Test the Battery (Figure 2)
1. Unplug the garage door opener. The battery status LED will
either glow solid orange indicating opener is operating on
battery power or will flash indicating low battery power.
NOTE: Make sure the garage door opener is unplugged.
2. Open and close the door using the remote control or door
control. The garage door opener may run slower if the battery
is not fully charged. The battery will take 24 hours to fully
charge.
3. Plug in the garage door opener. Verify the battery status LED is
flashing green, indicating the battery is charging.

Charge the Battery

The battery charges when the garage door opener is plugged into
a 110 Vac electrical outlet that has power and 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.
Instructions for replacement 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.
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.
