Maintenance instructions

Correct upkeep, recharging and
storage will prolong the life of
the battery and are essential if
warranty claims are to be con-
sidered.
Compliance with the points be-
low is important in order to max-
imise battery life:
Keep the surface of the battery
clean and dry
Do not open the battery
z
Do not top up with water
Be sure to read and comply
with the instructions for char-
ging the battery on the follow-
ing pages
Do not turn the battery upside
down
If the battery is not discon-
nected, the on-board elec-
tronics (e.g. clock, etc.) gradually
drain the battery. This can cause
the battery to run flat. If this hap-
pens, warranty claims will not be
accepted.
If the motorcycle is to be out of
use for more than four weeks,
disconnect the battery or con-
nect a suitable trickle charger to
the battery.
BMW Motorrad has de-
veloped a float 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 of disuse,
without having to disconnect the
battery from the motorcycle's
on-board systems. You can ob-
tain additional information from
your authorised BMW Motorrad
dealer.
Charging battery when
connected
Charging the connected
battery directly at the bat-
tery terminals can damage the
vehicle electronics.
Always disconnect the battery
from the on-board circuits be-
fore recharging it with a charger
connected directly to the battery
posts.
If you switch on the igni-
tion and the multifunction
display and telltale lights fail to
light up, the battery is completely
flat. Attempting to charge a com-
pletely flat battery via the on-
board socket can cause damage
to the motorcycle's electronics.
If a battery has discharged to the
extent that it is completely flat, it
has to be disconnected from the
on-board circuits and charged
with the charger connected dir-
ectly to the battery posts.
