V User Manual Impulse Pedelec 27
› 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. Aer 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 t 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 of between 50% and 75% at
a temperature of +10°C.
Observe the following points to increase the service
life of your Pedelec battery:
› Make sure that the battery is lly charged before
you ride your bike for the rst time or if you have
not used it for a while.
› You should run the battery all the way down to
empty for the rst three charging cycles. This
allows 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 equently dur-
ing normal operation, this has a favourable eect
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 aer a
short period of operation.
› In the as-delivered condition, the battery is not
lly 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.
