If the battery is not
disconnected, the
onboard electronics (clock
etc.) will drain the battery.
This can cause the battery
to run flat. If this happens,
warranty claims will not be
accepted.
During periods when the mo-
z
torcycle is not being used, of
more than four weeks, dis-
connect the battery from the
motorcycle or connect a trick-
le charger to the battery.
BMW Motorrad has de-
veloped a trickle-charger
specially designed for com-
patibility with the electronics
of your motorcycle. Using this
charger, you can keep the
battery charged during long
periods when the motorcy-
cle is not being used with-
out having to disconnect the
battery from the motorcycle's
onboard systems. Additional
information is available at your
authorized BMW Motorrad re-
tailer.
Charging connected bat-
tery
Charging the connect-
ed battery directly at the
battery terminals can damage
the motorcycle electronics.
To charge the battery via the
battery terminals, disconnect
the battery first.
If you switch on
the ignition and the
multifunction display and
indicator lights fail to light
up, the battery is completely
flat. Attempting to charge a
completely flat battery via the
onboard socket can cause
damage to the motorcycle's
electronics.
Always charge a completely
drained battery directly at the
terminals of the disconnected
battery.
Charging the battery via
the onboard socket is
only possible with suitable
chargers. Unsuitable charg-
ers can result in damage to
the motorcycle electronics.
Use BMW chargers with
the part numbers 71 60
7 688 864 (220 V) or
71 60 7 688 865 (110 V).
If in doubt, charge the
disconnected battery directly
at the terminals.
Charge the disconnect-
ed battery via the onboard
socket.
