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.
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.
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.
Charge via the power sock-
et, with the battery connec-
ted to the motorcycle's on-
board electrical system.
The motorcycle's
on-board electronics
know when the battery is
fully charged. The on-board
socket is switched off when
this happens.
Comply with the operating
instructions of the charger.
If you are unable to
charge the battery
through the power socket,
you may be using a charger
that is not compatible with
your motorcycle's electronics.
If this happens, disconnect
the battery from the on-board
systems and connect the
charger directly to the
battery.
