7.10 Reading the charge status LED display on Li­ion bat-
teries 7
NOTE
The charge status cannot be indicated while the power tool is in
operation. LED 1 blinks when the battery is fully discharged or
when it is too hot (temperature above 80°C). The battery must then
be inserted in the charger. If all 4 LEDs blink, this indicates that
the power tool has been overloaded or has overheated.
The Li-ion battery features a charge status LED display. The
charge status is indicated by the LEDs on the battery during
charging (please refer to the operating instructions for the charger).
When the battery is not in use, pressing one of the battery release
buttons or inserting the battery into the power tool causes the
battery charge status to be displayed by the four LEDs for three
seconds.
