Maintenance instructions
Correct battery maintenance
combined with proper charging
and storage procedures extends
the battery's service life, and is
also required for warranty claims.
Compliance with the points be-
low is important in order to maxi-
mize battery life:
Keep the surface of the battery
clean and dry
Do not open the battery
Do not top up with water
Be sure to read and comply
with the instructions for charg-
ing the battery on the following
pages
Do not turn the battery upside
down.
If the battery is not discon-
nected, the onboard elec-
tronics (clock etc.) will drain the
battery. This can cause the bat-
tery to run flat. If this happens,
warranty claims will not be ac-
cepted.
During driving breaks of more
than 4 weeks, a trickle-charger
should be connected to the
battery.
BMW Motorrad has devel-
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-
formation is available at your au-
thorized BMW Motorrad retailer.
Charge 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.
If the multifunction display
and indicator lamps fail to
light up when you switch on the
ignition, the battery is completely
