electrical power outage. If the battery voltage drops too
low, the batteries will disconnect and the motor unit will no
longer operate under battery power.

After the electrical power has been restored, the battery
will recharge within 48 hours. Under normal usage
batteries will last 3 to 5 years.

To obtain maximum battery life and prevent damage,
disconnect the battery when motor unit is unplugged for
an extended period of time.
