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
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
