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 pre-
vent the effect of the low temperature on the range of
the battery ➠ Chapter 5.4 "Warranty and service life".
5.3

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 con-
sult your specialist cycle shop.
› Please always supervise the battery charging
process 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. The battery
management activates the sleep mode after 48 hours with-
out use. The system exits the sleep mode when you press
the battery key.

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
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.
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.
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
expect the battery to age by approximately 3-5%
per year as a result of ageing and charging pro-
cesses.
Ensure that the battery does not become too hot.
The rate at which the battery ages increases signifi-
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, please ensure
that the battery is not charged during this period.
A fully charged battery ages at an even greater rate
than a partially charged one at high temperatures.
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.
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
