Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using it for the first time.
To charge the battery, read and follow the instructions in the
operating manual for the charger.
The battery can be charged at any state of charge. Interrupt-
ing the charging process does not damage the battery.
The battery has a temperature monitoring function which
only allows it to be charged within a temperature range of
0 °C to 40 °C.
Do not reconnect the battery to the charger until it has
reached the correct charging temperature.
Battery charge indicator
The five green LEDs on the battery charge indicator (6) in-
dicate the battery's state of charge of when the battery is
switched on.
Each LED represents approximately 20 % of the charging ca-
pacity. When the battery is fully charged, all five LEDs will be
lit.
The battery's state of charge when switched on is also shown
on the display of the on-board computer. Read and follow
the instructions in the operating manuals for the drive unit
and on-board computer.
If the battery capacity is less than 5 %, all the LEDs on the
battery charge indicator (6) on the battery will go out. The
display function of the on-board computer, however, will
carry on working.
Once charging is complete, disconnect the battery from the
charger and the charger from the mains.
