6 Battery

Your battery is a lithium cobalt battery, the ideal type of
lithium-ion (Li-ion) battery for this application. One of the
main benefits of this type of battery is its low weight com-
bined with a high capacity. Li-ion batteries only weigh half
as much as comparable nickel metal hybride or nickel-cad-
mium batteries. This means you carry less battery weight
and more battery power.
6.1

Straightforward charging

› There is no memory effect. You can therefore fully
recharge your battery after every trip.
› Recharge the battery after every trip. This means
you can set off immediately the next time you use
your bike and you also increase the service life of
the battery.
› If you are not using the battery, you must recharge
it after 6 months at the latest.
6.2 High degree of safety due to battery
management
› The battery cannot be damaged as a result of a
short-circuit. If this were to happen, the battery
management would switch off the battery.
› You can simply leave the battery standing in the
charger as it prevents overcharging.
6.3

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 enters sleep mode to prevent it from
totally discharging.
› 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.
20 III User Manual Pedelec with centre 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 after you
have not used it for a while.
› You should run the battery all the way down to
empty for the first three charging cycles. This al-
lows the battery to reach its maximum capacity.
› If you continuously run the battery to empty during
normal operation, this reduces its service life.
› If you partially recharge the battery frequently dur-
ing 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 battery is allowed
to discharge unchecked for an extended period this
can lead to total discharging which damages the
battery. To "wake up" the battery, simply place it in
the charger for one minute.
› If you are having problems with the battery, place
it in the charger for one minute. 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 tempera-
ture of between +10 °C and +30 °C. It takes longer
to charge the battery at low temperatures, the
battery will not charge up at temperatures higher
than +30 °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 charged to 75% of its capacity at a tem-
perature of +10°C.
