connect a trickle charger to the
8
battery.
BMW Motorrad has devel-
110
oped a trickle-charger spe-
cially designed for compatibility
with the electronics of your mo-
torcycle. Using this charger, you
can keep the battery charged
during long periods when the
motorcycle is not being used
without having to disconnect the
battery from the motorcycle's
onboard systems. Additional in-
z
formation is available at your au-
thorized BMW Motorrad retailer.
Charging connected
battery
Charging the connected
battery directly at the bat-
tery terminals can damage the
motorcycle electronics.
To charge the battery via the
battery terminals, disconnect the
battery first.
Charging the battery via
the onboard socket is only
possible with suitable chargers.
Unsuitable chargers can result in
damage to the motorcycle elec-
tronics.
Use BMW chargers with the
part numbers 71 60 7 688 864
(220 V) or, as applicable,
71 60 7 688 865 (110 V). If in
doubt, charge the disconnected
battery directly at the terminals.
If you switch on the igni-
tion and the multifunction
display and indicator lights fail to
light up, the battery is complete-
ly flat. Attempting to charge a
completely flat battery via the on-
board socket can cause damage
to the motorcycle's electronics.
Always charge a completely
drained battery directly at the
terminals of the disconnected
battery.
Charge disconnected battery
via onboard socket.
The motorcycle's onboard
electronics know when the
battery is fully charged. The
onboard socket is switched off
when this happens.
Comply with operating instruc-
tions of charger.
If you are unable to
charge the battery via
the onboard socket, you
may be using a charger that
is not compatible with your
motorcycle's electronics. In this
case, please charge the battery
directly at the terminals of the
disconnected battery.
