13.1.2. Charging the battery
When the weight display shows “lb” (Low battery), the battery voltage is low and
should be recharged. Turn the scale OFF and connect the AC power cable to an
electrical outlet. The charging process will start.
Charging will be performed when the AC power cable is connected to an electrical
outlet and the scale is turned OFF. If the scale is turned ON, trickle charging will be
performed.
The scale can be used while the battery is charging. After fully charged, the scale
will change the charging process to trickle charge automatically.
Notes
• Charge the battery at a temperature between 0°C (32°F) and 40°C (104°F),
preferably, at a range of 5°C (41°F) to 35°C (95°F) .
• Charge the battery when using for the first time.
• The battery must be recharged regularly, every 3 to 6 months, if the scale is
not used for a long period of time. More frequent recharging is required in a
warmer area.
