Observe the following points to increase the service 

life of your Pedelec battery: 

›

Make sure that the battery is fully charged before 

you ride your bike for the first time or if you have 

not used it for a while. 

›

You should run the battery all the way down to 

empty for the first three charging cycles. This al-

lows the battery to reach its maximum capacity. 

If you continuously run the battery to empty during 

normal operation, this reduces its service life. 

If you partially recharge the battery frequently dur-

ing normal operation, this has a favourable effect 

on its service life. 

›

You should therefore partially recharge the battery 

whenever possible: Try not to run the battery all 

the way down to empty and recharge it even after 

short periods of operation.

›

If you are having problems with the battery, place 

it in the charger for one minute. This resets the bat-

tery. After this, the battery will work again. 

›

Ideally you should charge the battery at a tempera-

ture of between +10°C and +30°C. It takes longer 

to charge the battery at low temperatures, the 

battery will not charge up at temperatures higher 

than +30°C. Ideally, you should charge and store 

the battery inside your house or in a warm garage 

when the outside temperature is low. In this case 

you should only fit the battery on your bike just 

before using it. 

›

If you are transporting your Pedelec by car, take 

the battery out of its holder and transport it 

separately.

›

The battery should ideally be stored for longer 

periods with a charge of between 50% and 75% at 

a temperature of +10°C.

7.4   Battery information system 

There is a display panel on the top of the battery which 

contains four LEDs and a button. The LEDs light up if you 

press the button. Information about the battery and its 

charge state is provided based on the number of LEDs that 

light up and the way in which they light up.

If the battery is empty, it will work once again 

briefly following a short period of rejuvenation and 

will then switch back off. It must now be charged.

›

Check the battery charge before every trip to make 

sure it is sufficient for the planned journey.
