The age of the battery.
A battery also ages during storage.
An 11 Ah battery with lithium-ion cells loses around
4-5% of its initial capacity each year. A 15 Ah bat-
tery with lithium-nickel-cobalt-aluminium-
oxygen cells around 2-3%.
This means: Even if you do not use your battery, its
capacity reduces. With everyday use, you can ex-
pect the battery to age by approximately 3-5% per
year as a result of ageing and charging processes.
•
You can extend the service life of the battery by
fully recharging it after every journey, however
short. The Xion Li-ion battery has no memory
effect.
•
You can also extend the service life of the bat-
tery by using the assistance selectively. Ideally,
you should ride in low gears with a high pedal-
ling cadence.
•
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.
7.5 Service life and warranty
Your Xion system is a high-quality drive system which was
manufactured in Germany. All components come with a
two-year warranty. The battery is a wear part
(

Chapter
7.5.1 “Service life and warranty of the battery”) . Bear in
mind that, due to the higher average speed and greater
distances that can be achieved with your Pedelec com-
pared to a normal bike, all wear parts are subjected to
greater wear.
7.5.1 Service life and warranty
of the battery
Batteries are wear parts. Wear parts come with a two-year
warranty.
If the battery develops a fault during this period, your
specialist cycle shop will of course replace it. Normal
ageing and battery wear do not constitute a fault.
The service life of the battery depends on different factors.
The most important wear-relevant factors are:
•
The number of charging processes
After 1,100 charging cycles, your battery will still
have 60% of its initial capacity, providing it has
been well looked after. This means 6.6 Ah in an
11 Ah battery and 7.2 Ah in a 15.5 Ah battery. A
charging cycle is defined as the sum of the indi-
vidual charges until the charges reach the overall
capacity of the battery.
For example: You charge the battery with 5 Ah on
the first 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.
From the technical standpoint therefore, the bat-
tery is exhausted at this point. Providing you can
still cover the journey distances with the remaining
battery capacity, you can of course continue using
it. If the capacity is no longer sufficient, you can
take your battery to a specialist cycle shop who
will dispose of your battery and sell you a new one.
