Warranty and service life

Batteries are wear parts. Wear parts come with a two-year
warranty.
If a fault occurs during this period, your specialist cycle
shop will replace the battery. Normal ageing and battery
wear do not constitute a fault.
The service life of the battery depends on diferent factors.
The most important wear-relevant factors are:
• The number of charges
Ater 1,100 charging cycles, your battery will still
have 60% of its initial capacity, providing it has
been well looked ater. This means 6.6 Ah in an 11
Ah battery and 7.2 Ah in a 15.5 Ah battery. A charg-
ing cycle is deined as the sum of the individual
charges until the battery has been charged to ull
capacity once.
For example: You charge the battery with 5 Ah on
the irst day, 2 Ah on the second day and 4 Ah on
the third day; the sum is 11 Ah. The battery has
thereby completed one charge cycle.
According to the technical deinition, the battery is
exhausted when less than 60% of the initial capac-
ity is available. If you can still ride the distances
you require with the remaining battery capacity,
you can of course continue using it. If the capacity
is no longer suicient, you can take your battery to
a specialist cycle shop, which will dispose of your
battery and sell you a new one.
•
The age of the battery
A battery also ages during storage.

This means that even if you do not use your bat-
tery, its capacity reduces. You can expect the bat-
tery to age by approximately 3 to 5%.
Ensure that the battery does not become too hot.
The rate at which the battery ages increases signii-
cantly at temperatures above 40°C. Direct sunlight
can heat the battery considerably. Be sure not to
leave the battery in a hot car, and always stand
your Pedelec in the shade during breaks in cycle
trips. If you cannot prevent exposure to heat, do
not charge the battery until it has cooled down.
A ully charged battery ages at an even greater rate
than a partially charged one at high temperatures.
•
If you always ride with maximum motor output,
your motor will always require a higher current.
Higher currents cause the battery to age more
quickly.
•
You can also extend the service life of the bat-
tery by using the assistance selectively. Use a
low assist level when riding. With lower dis-
charge currents, you conserve your battery.
Make sure that the battery is ully charged before
you ride your bike for the irst time or if you have
not used it for a while.

Storage

If you do not need your battery for a while, store it at a
temperature of 18 – 23°C at 50–70% of its ull charge ca-
pacity. If you do not use the battery for six months, you
must recharge it.

Ordering a replacement key

We recommend you note down the key number on the
receipt. If you lose the key, you can order a replacement
key using this number.
If you no longer have the key number, the only option is
to remove the bicycle lock. Contact your specialist cycle
shop in this case.
