Operation
Indicators on the charger
There are different indicators on the charger
• Green LED flashes about once a second:
Charging.
• Green LED lights up continuously:
Battery fully charged; charging complete
• Green LED flashes briefly every 2 seconds:
No battery is connected; battery is not being
charged
• Red LED flashes: Charging error.
If there is a charging error, first check that
connectors are positioned correctly, there is no
dirt and no cables are buckled. If the charger
has a magnetic connector, check the magnetic
connector on the charger and the magnetic
socket on the battery for dirt from time to time
or there is a problem during charging. Metal
chips and small parts such as washers
accumulate there quickly due to the magnet.
Charging time
A full charge (0%–100%) takes almost 4 hours.
The charger supplies an average charging current
of 4 A. This means that it charges at an average
of 4 A over a full charge cycle (fully discharged
battery to fully charged battery). The charging
process is complete when the battery level
indicator LEDs go out.

If the battery is fully charged, the charger
switches off.
The green LED on the charger lights up
continuously and the LEDs on the battery go
out.
The battery is automatically placed in sleep
mode after the charger plug is disconnected.
