loses its ability to maintain a charge, it will need to be replaced (P/N BAT0013).
Before changing the battery, execute the Battery Conditioning sequence above to
ensure the battery can no longer hold a charge. Also refer to the Battery Voltage
Levels section below for further troubleshooting. If required, replace the battery
following these steps:
1. Remove any items from the scale platter and unplug the power cord from the
rear of the scale.
2. Remove the scale platter and set it aside.
3. Turn the scale over and remove the Phillips head screw on the battery
compartment cover.

lot of force. If the connector will not go in place, check to make sure the
connector has the correct orientation.
