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 us-
ing other battery packs, Bosch shall not assume any liabil-
ity and warranty.
Switching On and Off
Switching on the battery pack is one of the ways of switching on
the eBike system. When doing so, read and observe the operat-
ing instructions of the drive unit and on-board computer.
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:
If the capacity of the battery pack is below 5 %, no LED
on the charge-control indicator A3 lights up. It is only visible
on the on-board computer, 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.
If no power is drawn from the eBike drive for about 10 min-
utes (e.g. because the eBike is not moving) and no button is
pressed on the on-board computer or the operating unit of the
eBike, the eBike system and therefore also the battery pack
will shut down automatically 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 Bosch eBike
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 feature and the battery-pack capacity may be
strongly reduced.
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.
