voltage 6 V, capacity 4 Ah
Charging batteries:
The charger automatically detects the voltage of
the battery, and charges the pack according to
the constant current / constant voltage principle.

1. Connect the charger to an easily accessible
mains power socket (120-240V~, 50/60 Hz).
The red LED flashes once to confirm that
the charger is ready for use.

charged to the attachment plugs of the char-
ging cable. Make absolutely sure that the po-
larity of the battery and the polarity of the
charging cable match.
• RED to positive pole (+)
• BLACK to negative pole
The red LED lights up to indicate that
charging is in progress.
3. The LED glows green when the lead-acid
battery is fully charged. Disconnect the bat-
tery from the charge lead, and disconnect
the charger from the mains socket.
Additional information:
If the green control lamp does not switch on
after connecting the battery to the charger and
