BatteryMaintenance instructionsYour motorcycle is supplied
with a maintenance-free
battery.
Correct upkeep, recharging
and storage will prolong the
life of the battery and are
essential if warranty claims are
to be considered.
Compliance with the points
below is important in order to
maximise battery life: – Keep the surface of the bat-
tery clean and dry.
– Do not open the battery.
– Do not top up with water.
– Be sure to read and comply with the instructions for
charging the battery on the
following pages.
– Do not turn the battery upside down.
If the battery is not dis-
connected, the on-board
electronics (clock, etc.) will
drain the battery. This can
cause the battery to run flat. If
this happens, warranty claims
will not be accepted.
If the motorcycle is to be out of
use for more than two months,
disconnect the battery or con-
nect a suitable trickle charger
to the battery. c BMW Motorrad has de-
veloped a trickle-charger
specially designed for
compatibility with the electron-
ics of your motorcycle. Using
this charger, you can keep the
battery charged during long
periods of disuse, without hav-
ing to disconnect the battery
from the motorcycle's on-
board systems.
More information is available
on request from your
authorised BMW motorcycle
dealer. c
Charging the battery
when connected If the telltale lights do not light
up and the multifunction dis-
play remains blank when you
switch on the ignition, the bat-
tery is completely flat.

Maintenance
• Charge the disconnected battery via the power socket.
• Comply with the operating instructions of the charger.
Attempting to charge a
completely flat battery via
the on-board socket can
cause damage to the motorcy-
cle's electronics. If the battery
is completely flat it must al-
ways be recharged directly at
the terminals. c
• Do not attempt to recharge a completely flat battery via
the on-board socket;
instead, disconnect the bat-
tery from the on-board sys-
tem and connect the charger
directly to the battery
terminals.
• Comply with the operating instructions of the charger. Your authorised BMW
motorcycle dealer will be
happy to provide information
on suitable chargers. c
If the battery is only partially
discharged, it can be re-
charged via the on-board
socket.
• If electrical accessories are connected to an additional
on-board socket
OA, discon-
nect them before connecting
the charger.
• Switch on the ignition.
• Plug the charger into the on-
board socket. Comply with
the operating instructions of
the charger.
• Switch off the ignition. The motorcycle's on-
board electronics know
when the battery is fully
charged. The on-board socket
is switched off when this
happens. c
If you are unable to
charge the battery via the
power socket, you may be us-
ing a charger that is not com-
patible with your motorcycle's
electronics. If this happens,
disconnect the battery from
the on-board systems and
connect the charger directly to
the battery. c

Charging the battery
when disconnected
The battery has to be re-
charged at regular inter-
vals in the course of a lengthy
period of disuse.
See the instructions for caring
for your battery. Always fully
recharge the battery before
restoring it to use. c
• Charge the battery using a suitable charger.
• Comply with the operating instructions of the charger.
• Once the battery is fully charged, disconnect the
charger terminal clips from
the battery terminals.
