2. Grip the battery with both hands and lift it forwards/
upwards out of its holder. In doing so, hold on tight to

Learning cycle

After fully charging the battery for the first time and
thereafter roughly once every six months, you must run
the battery down until the system switches off. This
procedure (a so-called "learning cycle") is necessary
so that the battery management recognises the chang-
es in the capacity caused by age and wear and tear,
in other words, the performance level of the battery.
Afterwards, the capacity of the battery is calculated
anew and correctly represented. This also allows the
remaining range display to function with greater preci-
sion. With this procedure, you can prevent a sudden
loss of electrical assistance during an extended trip.

Charging operation

Before charging the battery, read the information on
the charger carefully.
1. Take the charger provided out of its packaging and
plug the mains plug into a socket (110 to 230 V, please
observe type plate on the charger). To charge the bat-
tery safely, the charger must be placed on a suitable
surface. This should be dry and non-flammable.
2. Connect the plug of the charger to the battery. When
positioned correctly, the plug is held in the socket by a
magnet.
Charging the battery
3. The charging process begins. The LED on the charger
lights up red. The battery is charged in five stages.
When charging of one stage is in progress, the cor-
responding LED flashes. If this stage has been fully
charged, the LED will light up permanently. Now the
next LED will begin to flash. After all five LEDs have
gone out, the battery is fully charged.
4. If the LED on the charger flashes red permanently, a
charging fault has developed. In that case, disconnect
the battery from the charger, then connect it again. The
charger tests the battery and performs readjustments,
if required. If the LED on the charger still flashes, take
the charger and battery to your specialist dealer who
will test the device and replace it, if required.
5. To save power, pull the charger plug out of the socket
once the charging operation is complete.
