Technical Data
Assembly
 Place down the battery pack only on clean surfaces. In
particular, avoid soiling the charge socket and the con-
tacts, e.g. by means of sand or ground.
Checking the Battery Pack Before Using
for the First Time
Check the battery pack before charging it or using it with your
eBike for the first time.
For this, press the On/Off button A4 to switch on the battery
pack. When no LED of the charge-control indicator A3 lights
up, the battery pack may be damaged.
When at least one, but not all LEDs of the charge-control indi-
cator A3 is lit, then fully charge the battery pack before using
for the first time.

Do not charge a damaged battery pack and do not use
it. Please refer to an authorised bicycle dealer.
Charging the Battery Pack
 Use only the charger provided with your eBike or an
identical original Bosch charger. Only this charger is
matched to the lithium-ion battery pack used in your eBike.
Note: The battery pack is supplied partially charged. To en-
sure full battery pack capacity, completely charge the battery
pack in the charger before using for the first time.
For charging the battery pack, read and observe the operating
instructions of the charger.
The battery pack can be recharged at any time on its own or on
the bike without shortening the lifespan. Interrupting the
charging process does not damage the battery pack.
The battery pack is equipped with a temperature control indi-
cator, which enables charging only within a temperature
range between 0 °C and 40 °C.
When the battery pack is not
within the charging-tempera-
ture range, three LEDs of the
charge-control indicator A3
flash. Disconnect the battery pack from the charger until its
temperature has adjusted.
Do not connect the battery pack to the charger until it has
reached the allowable charging temperature.
Charge-control Indicator
When the battery pack is switched on, the five green LEDs of
the charge-control indicator A3 indicate the charge condition
of the battery pack.
In this, each LED indicates approx. 20 % capacity. When the
battery pack is completely charged, all five LEDs light up.
The charge-control of the switched on battery pack is also in-
dicated on the display of the HMI. Read and observe the oper-
ating instructions of the drive unit and the HMI.
When the capacity of the battery pack is below 5 %, all LEDs
of charge-control indicator A3 on the battery pack go out;
however, the drive HMI does provide an additional indication
function.

Inserting and Removing the Battery Pack
(see figures C–D)
 Always switch the battery pack off when inserting or
removing it from the holder.
In order for the battery pack to be inserted, the key A5 must
be inserted into the lock A6 and the lock must be unlocked.
To insert the standard battery pack A8, place it with the
contacts on the lower holder A9 on the eBike (the battery
pack can be inclined up to 7° to the frame). Tilt it into the up-
per holder A7 until it engages.
To insert the rack-type battery pack A2, slide it with the
contacts facing ahead until it engages in the holder A1 of the
rear rack/carrier.
Check if the battery pack is tightly seated. Always lock the
battery pack with lock A6, as otherwise the lock can open and
the battery pack could fall out of the holder.
After locking, always remove the key A5 from the lock A6.
This prevents the key from falling out and the battery pack
from being removed from unauthorised persons when the
eBike is parked.
To remove the standard battery pack A8, switch it off and
unlock the lock with the key A5. Tilt the battery pack out of the
upper holder A7and pull it out of the lower holder A9.
To remove the rack-type battery pack A2, switch it off and
unlock the lock with the key A5. Pull the battery pack out of
the holder A1.
Operation
Initial Operation
 Use only original Bosch battery packs approved for
your eBike by the manufacturer. Using other battery
packs can lead to injuries and pose a fire hazard. When
using other battery packs, Bosch shall not assume any
liability and warranty.
Switching On and Off
Switching the battery pack on is one of the possibilities to
start the eBike system. Read and observe the operating in-
structions of the drive unit and the drive HMI.
Before switching on the battery pack or the eBike system,
check that the lock A6 is locked.
To switch on the battery pack, press the On/Off button A4.
The LEDs of indicator A3 light up and at the same time indi-
cate the charge condition.
Note: When the battery-pack capacity is below 5 %, none of
the LEDs of charge-control indicator A3 will light up. Only the
drive HMI will indicate if the eBike system is switched on.
To switch off the battery pack, press the On/Off button A4
again. The LEDs of indicator A3 go out. This also switches off
the eBike system.
When no power output of the eBike drive is requested for ap-
prox. 10 minutes (e. g., because the eBike is parked) and no
button of the drive HMI or operating unit is pressed, the eBike
system and thus the battery pack automatically switch off to
save energy.
The battery pack is protected against deep discharging, over-
charging, overheating and short-circuiting through the “Elec-
tronic Cell Protection (ECP)”. In case of hazardous situations,
a protective circuit automatically switches off the battery
pack.
When a defect of the battery
pack is detected, two LEDs of
the charge-control indicator A3
flash. In this case, please refer
to an authorised bicycle dealer.
Notes for Optimum Handling of the Battery Pack
The battery-pack life can be prolonged when being properly
maintained and especially when being operated and stored at
the right temperatures.
With increasing age, however, the battery-pack capacity will
diminish, even when properly maintained.
A significantly reduced operating period after charging indi-
cates that the battery pack is worn out and must be replaced.
You can replace the battery pack yourself.
Recharging the Battery Pack prior to and during Storage
When not using the battery pack for a longer period, charge it
to approx. 60 % (3 to 4 LEDs lit on the charge-control indica-
tor A3).
Check the charge condition after 6 months. When only one
LED of the charge-control indicator A3 lights up, recharge the
battery pack again approx. 60 %.
Note: When the battery pack is stored discharged (empty) for
longer periods, it can become damaged despite the low self-
discharging and the battery-pack capacity may be strongly re-
duced.
It is not recommended to have the battery pack connected
permanently to the charger.
Storage Conditions
Store the battery pack in a dry, well-ventilated location. Pro-
tect the battery pack against moisture and water. Under unfa-
vourable weather conditions, it is recommended e.g. to re-
move the battery pack from the eBike and store it in an
enclosed location until being used again.
The battery pack can be stored at temperatures between
–10 °C and +60 °C. For a long battery-pack life, however,
storing the battery pack at a room temperature of approx.
20 °C is of advantage.
Take care that the maximal storage temperature is not ex-
ceeded. As an example, do not leave the battery pack in a ve-
hicle in summer and store it out of direct sunlight.
It is recommended to not store the battery pack on the bike.
