RECHARGING BATTERY
WARNING
Wrong battery type or charging mode
Battery damage and risk of fire
Use the battery charger only for
rechargeable 12 V lead-acid and
lithium-ion batteries. Never attempt to
charge NiCd, NiMh, or primary cells
(non-rechargeable batteries).
Before starting the charging process,
you must always make sure that the cor-
rect battery type/charging mode has
been selected.
Connect the Plus battery charger to the
on-board socket.
Charging starts automatically.
If
No battery
appears in the display al-
though the Plus battery charger is connected
via the on-board socket, the battery is too
deeply discharged to recharge via the on-
board socket. The battery will have to be
charged with the battery charger connected
directly to the battery terminals.
Disconnect the battery from the motor-
cycle.
Connect the adapter cable to the Plus bat-
tery charger.
Connect the crocodile clips of the adapter
to the battery terminals.
Be sure to connect the red crocodile clip
to the battery’s positive terminal and the
black crocodile clip to the battery's neg-
ative terminal. If
Short / reversed
polarity
appears in the display, either
the crocodile clips have come into contact
with each other or polarity is reversed.
Eliminate the short circuit between the
crocodile clips or connect the crocodile
clips to the correct terminals, as applic-
able.
Charging starts automatically.

progress in the display.

gress as a progress bar and a percentage
reading. Charge current and charge voltage
are shown in the bottom display line.
The Plus battery charger switches automat-
ically to float charging as soon as the battery
is fully charged.
The time it takes to charge the battery de-
pends on the battery's initial state of charge
and its age, and also on the size of the bat-
tery.

PAUSES IN CHARGING
On account of the vehicle electronics, there
is a possibility of pauses in charging occur-
ring when the battery is being charged via
the motorcycle’s on-board socket.
Pauses in charging can occur in different
charge states.
Charge 30 % Pausing
(example) appears in the display.

the vehicle electronics are clear for charging.
FLOAT CHARGING
ATTENTION
Long charging without overvoltage pro-
tection
Damage to the battery charger
To prevent damage due to overvoltage,
it is advisable to use additional over-
voltage protection (e.g. power-socket
adapter with surge protector) when
charging over a prolong period.
The Plus battery charger can remain connec-
ted to the battery for months after charging
has completed. The battery is monitored
and the charge is topped up as necessary.
Float charging (battery maintenance) is car-
ried out.
