Battery Management; Sleep Mode; Warranty And Service Life - Univega Bicycle Original User Manual

The range of the battery is less in winter due to
the lower temperatures. Only move the battery
from the warm room where you store it and fit it
on your Pedelec just before you set off. This will
help to prevent the effect of the low temperature
on the range of the battery. ➠ Chapter 5.4 "War-
ranty and service life".

Battery management

The battery management monitors the temperature of
your battery and warns you of incorrect use.
If an external short-circuit has been caused at the
contacts or the charging socket, please consult
your specialist cycle shop.
Please always supervise the battery charging pro-
cess and disconnect the charger afterwards.

5.3.1 Sleep mode

The battery management switches the battery to sleep
mode to prevent a so-called total discharge. At the latest,
the battery management activates the sleep mode after
ten days without use. The system exits sleep mode when
you connect the battery to the charger or press the battery
key or push button on the battery. This "wakes up" the
battery.
Down tube battery: If the battery does not wake
up, the cell voltage may be too low. In this case,
connect up the charger and press the battery key.
The battery is charged for one minute.
Seat tube battery: The battery can also be put into
sleep mode manually. To do so, press the push
button for eight seconds. Release the push button
as soon as the second LED lights up.

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 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 charg-
ing cycle is defined as the sum of the individual
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.
According to the technical definition, 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 sufficient, 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.
This means: Even if you do not use your battery, its
capacity reduces. You can expect the battery to age
by approximately 3 to 5%.
Ensure that the battery does not become too
hot. The rate at which the battery ages increases
significantly 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.
