If at least one (but not all) of the LEDs on the battery charge
indicator

(3)

lights up, the battery will need to be fully

charged before using it for the first time.

Do not charge or use batteries if they are damaged.

Contact an authorised bicycle dealer.

Charging the battery

A Bosch eBike battery must only be charged using an
original Bosch eBike charger.

Note:

The battery is supplied partially charged. To ensure

full battery capacity, fully charge the battery in the charger
before using it for the first time.
To charge the battery, read and follow the instructions in the
operating manual for the charger.
The battery can be charged at any state of charge. Interrupt-
ing the charging process does not damage the battery.
The battery has a temperature monitoring function which
only allows it to be charged within a temperature range of

0 °C

40 °C

If the temperature of the bat-
tery is outside this charging
range, three of the LEDs on
the battery charge indicator

(3)

will flash. Disconnect the

battery from the charger and
let it acclimatise.

Do not reconnect the battery to the charger until it has
reached the correct charging temperature.

Battery charge indicator

The five green LEDs on the battery charge indicator

(3)

in-

dicate the battery's state of charge of when the battery is
switched on.
Each LED represents approximately 20 % of the charging ca-
pacity. When the battery is fully charged, all five LEDs will be
lit.
The battery's state of charge when switched on is also shown
on the display of the on-board computer. Read and follow
the instructions in the operating manuals for the drive unit
and on-board computer.
If the battery capacity is less than 5 %, all the LEDs on the
battery charge indicator

(3)

on the battery will go out. The

display function of the on-board computer, however, will
carry on working.
Once charging is complete, disconnect the battery from the
charger and the charger from the mains.

Using two batteries for one eBike (optional)

The manufacturer can also equip an eBike with two batter-
ies. In this case, one of the charging sockets will not be ac-
cessible or it will have been sealed with a sealing cap by the
bicycle manufacturer. Only charge the batteries via the char-
ging socket that is accessible.

Never open charging sockets that have been sealed by
the manufacturer.

Charging batteries via a charging

socket that used to be sealed may cause irreparable dam-
age.

If you want to use an eBike that is designed for two batteries
with only one battery, cover the contacts of the unused
socket using the cover

(10)

provided. Otherwise there is a

risk that the exposed contacts will cause a short circuit (see
figures A and B).

Charging process for two batteries

If two batteries are fitted to an eBike, both batteries can be
charged using the uncovered connection. To begin with,
both batteries are charged one after the other until they
reach approx. 80–90 % capacity, then they are both fully
charged at the same time (the LEDs flash on both batteries).
When the bike is in operation, power is drawn from both bat-
teries on an alternating basis.
If you take the batteries out of the holders, you can charge
each one individually.

Charging with one battery fitted

If only one battery is fitted, you can only charge the battery
that has the accessible charging socket on the bike. You can
only charge the battery with the sealed charging socket if
you take the battery out of the holder.

Inserting and removing the battery

Always switch off the battery and the eBike system
when inserting the battery into the holder or remov-
ing it from the holder.

Inserting and removing the standard battery
(see figure A)

In order for the battery to be inserted, the key

must be

inserted into the lock

and the lock must be open.
