General information
Charging process
The weighing system is equipped with a rechargeable lithium-ion battery and an
intelligent battery charger. New lithium-ion batteries must be charged for at least
8 hours before first use. The battery can subsequently also be used when not fully
charged. In this case, the remaining operating time is reduced.
It takes 6 to 7 hours to fully charge the battery. In the case of partially discharged
batteries, the charging time is reduced accordingly. Charging continues automatically
after a power failure.
The charging process can be interrupted and continued as a partial charge. To do
so, disconnect the charger from the power supply.
Once the battery is fully charged, the charger stops automatically. The LED on the
charger lights up green.
In this case:
– Disconnect the charger from the power supply.
– Remove the battery from the charger.
– Place the battery in the weighing system – see page 47.
If the battery has not been fully charged after 8 hours, the charger stops
automatically. The LED on the charger lights up red.
In this case:
– Disconnect the charger from the power supply.
– Have the battery and/or charger repaired or replaced – see page 102 and see
Battery service life
The charge capacity of the battery will gradually diminish over time and with
repeated use. If the operating time with a fully charged battery gets shorter and
shorter, it is time to replace the battery – see page 103. Correct use and charging
will extend the service life.
Permissible temperatures
The service life of the battery will be extended if the permitted temperature ranges
are observed.
During operation:
-10°C to +50°C
During charging:
0°C to +40°C
During storage:
+10°C to +20°C
