Straightforward storage

• If you do not need your battery for a while, store it
at a temperature of +10°C at three quarters of its
full charge capacity.
• The battery management switches the battery to
sleep mode to prevent a so-called total discharge.
This can occur after different lengths of time with-
out being used. Depending on the charge state
of the battery, this can occur earlier with a lower
charge and later with a higher charge. The mana-
gement system activates the sleep mode after
48 hours without using the battery. The system
exits sleep mode when you press the button with
LED on the battery.
These benefits are available due to highly effective
battery management that has been adapted to this
specific application and by tuning the battery for
operation with a 250 watt motor.
Observe the following points to increase the service
life of your Pedelec battery:
› Make sure that the battery is fully charged before
you ride your bike for the first time or if you have
not used it for a while.
› If you continuously run the battery to empty
during normal operation, this reduces its ser-
vice life. If you partially recharge the battery
frequently during normal operation, this has a
favourable effect on its service life.
› You should therefore partially recharge the
battery whenever possible: Try not to run the
battery all the way down to empty and recharge
it even after a short period of operation.

› In the as-delivered condition, the battery is not
fully charged and is in what is referred to as
sleep mode. Sleep mode minimises the rate at
which the battery discharges itself. If the bat-
tery is allowed to discharge unchecked for an
extended period this can lead to total discharg-
ing which damages the battery. To "wake up" the
battery, simply charge it up again.
› If you are having problems with the battery,
charge it for one minute initially. A reset occurs,
during which the battery management disables
sleep mode, for example. After this, the battery
will work again.
› Ideally you should charge the battery at a tem-
perature of between +10°C and +30°C. It takes
longer to charge the battery at low temperatures,
while the battery will not charge up at tempera-
tures higher than +45°C. Ideally, you should
charge and store the battery inside your house or
in a warm garage when the outside temperature
is low. In this case you should only fit the battery
on your bike just before using it.
› If you are transporting your Pedelec by car, take
the battery out of its holder and transport it
separately.
› The battery should ideally be stored for longer
periods with a charge state of 50% to 75% at a
temperature of +10°C.
