14 Original User Manual | Pedelec Impulse 2.0
11Ah battery and 7.2 Ah in a 15.5 Ah battery. A
charging cycle is dened 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 rst 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 denition, the battery
is exhausted when less than 60% of the initial
capacity is available. 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 sucient, you can take your
battery to a specialist cycle shop who will dispose
of your battery and sell you a new one.
• 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.
Ensure that the battery does not become too
hot. The rate at which the battery ages increases
signicantly 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,
please ensure that the battery is not charged dur-
ing this period.
A lly 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 lly charged before you
ride your bike for the rst time or if you have not used
it for a while.
5.5 Storage
If you do not need your battery for a while, store it at a
temperature of +10°C at 50–70% of its ll charge capac-
ity. If you do not use the battery for six months, you must
recharge it.
5.6 Shipping
Do not ship batteries! A battery is a hazardous
article which can overheat and catch re in certain
conditions.
The preparation and shipping of a battery may only be
carried out by trained personnel.
If you would like to return your battery for replacement,
please always arrange this via your specialist cycle shop.
Specialist cycle shops can have the battery picked up ee
of charge and in compliance with dangerous goods legisla-
tion.
5.7 Disposal
Batteries are not to be disposed of with domestic waste.
Consumers are legally bound to dispose of used or dam-
aged batteries at the locations designated for the purpose
(battery collection point or specialist cycle shop).
