Charging process interrupted
If the „Fault" display lights up and the charge process is
interrupted, press the RESET button. The battery charger is
restarted.
If the „Fault" display is still lit up together with:
• the „50 % of battery capacity" display, the battery is
faulty and needs to be replaced.
• the „80 % of battery capacity" display, the battery
cannot hold the charge. The battery must be replaced.
• the „Battery discharged" display, it is not possible to
charge the battery. Contact a qualified specialist
workshop.
Note
Lithium batteries must be activated for charging if
necessary. When the lithium battery is connected, press the
RESET button for at least ten seconds until one of the
indicator lamps (5-8) lights up.
If the „Fault" display continues to light up, please contact a
qualified specialist workshop.
If the „100 % battery capacity" (trickle charge) display does
not light up after a charging time of 50 h (or 24 h for lithium
batteries), there is a fault. Contact a qualified specialist
workshop.
