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 of disuse, without
having to disconnect the bat-
tery from the motorcycle's
on-board systems. You can
obtain additional information
from your authorised BMW
Motorrad dealer.
Charging battery when
connected
Charging the connec-
ted battery directly at the
battery terminals can damage
the vehicle electronics.
Always disconnect the battery
from the on-board circuits be-
fore recharging it with a char-
ger connected directly to the
battery posts.
Only chargers suitable
for this mode of charging
can be used to recharge the
battery via the on-board sock-
et. Unsuitable chargers could
cause damage to the motor-
cycle's on-board electrics.
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 you are in doubt,
disconnect the battery from
the on-board systems and
connect the charger directly
to the battery.
If you switch on the ig-
nition and the multifunc-
tion display and telltale lights
fail to light up, the battery is
completely flat. Attempting to
charge a completely flat bat-
tery via the on-board socket
can cause damage to the mo-
torcycle's electronics.
If a battery has discharged to
the extent that it is completely
flat, it has to be disconnec-
ted from the on-board circuits
and charged with the char-
ger connected directly to the
battery posts.
Charge via the power sock-
et, with the battery connec-
ted to the motorcycle's on-
board electrical system.
Comply with the operating
instructions of the charger.
The motorcycle's
on-board electronics
know when the battery is
fully charged. The on-board
socket is switched off when
this happens.
Charging battery when
disconnected
Charge the battery using a
suitable charger.
Comply with the operating
instructions of the charger.
