Operation; Switching On/Off - Bosch PowerTube 750 Originalbetriebsanleitung

❶ To insert the PowerTube battery (4), place it so that its
contacts are in the lower holder of the frame.
❷ Push the battery upwards until it is held by the safety
restraint (8).
❸ Hold the lock open with the key and press the battery
upwards until you hear it click into place. Check that
the battery is secure in all directions.
❹ Always secure the battery by closing the lock (2) –
otherwise the lock may open and the battery may fall
out of the holder.
Always remove the key (1) from the lock (2) after locking it.
This prevents both the key from falling out and the battery
from being removed by unauthorised third parties when the
eBike is not in use.
Removing the PowerTube battery (axial) (see figure C)
❶ To remove the PowerTube battery (12), open the
lock (2) using the key (1), remove the key (1) and fold
the locking mechanism (9) to the side.
❷ Use the pull strap (10) to pull the battery (12) out of
the frame.
Note: As a result of varying designs, the battery may need
to be inserted and removed using a different method. Read
the operating instructions of the eBike manufacturer.
Inserting the PowerTube battery (axial) (see figure D)
In order for the battery to be inserted, the locking mechan-
ism (9) must be folded to the side. At this point, the key (1)
must not be inserted in the battery lock (2).
❶ To insert the PowerTube battery, insert it into the
frame with the socket for the charging connector (5)
facing upwards until the battery clicks into place.
❷ Close the locking mechanism (9), insert the key (1)
into the battery lock (2) and secure the battery. Make
sure that the safety hook (3) is hooked in at the open-
ing of the axial rail (11).
❸ Check that the battery is secure in all directions.
Always remove the key (1) from the lock (2) after locking it.
This prevents both the key from falling out and the battery
from being removed by unauthorised third parties when the
eBike is not in use.

Operation

Start-up
Use only original Bosch batteries that the manufac-
u
turer has approved for your eBike. Using other batter-
ies can lead to injuries and pose a fire hazard. Bosch ac-
cepts no liability or warranty claims if other batteries are
used.

Switching on/off

Switching on the battery is one way to switch on the eBike
system. Read and follow the instructions in the operating
manuals for the drive unit and on-board computer.
Bosch eBike Systems
Before switching on the battery, i.e. the eBike system, make
sure that the lock (2) is closed.
To switch on the battery, press the on/off button (7). Do not
use any sharp or pointed objects to press the button. The
LEDs on the indicator (6) will light up, indicating the bat-
tery's state of charge at the same time.
Note: If the battery capacity is less than 5 %, none of the
LEDs on the battery charge indicator (6) will light up.
Whether the eBike system is switched on is only visible on
the on-board computer/control unit.
To switch off the battery, press the on/off button (7) again.
The LEDs on the indicator (6) will go out. This will also
switch the eBike system off.
If no power is drawn from the eBike drive for
about 10 minutes (e.g. because the eBike is not moving) and
no button is pressed on the on-board computer or the con-
trol unit of the eBike, the eBike system will switch off auto-
matically.
The battery is protected against deep discharge, overload-
ing, overheating and short-circuiting by the "Electronic Cell
Protection (ECP)". In the event of danger, a protective cir-
cuit switches the battery off automatically.
Recommendations for optimal handling of the
battery
The service life of the battery can be extended if it is looked
after well and especially if it is stored at the correct temper-
ature.
As it ages, however, the capacity of the battery will diminish,
even with good care.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated. You can replace the
battery.
Recharging the battery before and during storage
When you are not going to use the battery for an extended
period (longer than three months), store it at a state of
charge of around 30 % to 60 % (when two to three of the
LEDs on the battery charge indicator (6) are lit).
Check the state of charge after six months. If only one of the
LEDs on the battery charge indicator (6) is lit, charge the
battery back up to around 30 % to 60 %.
Note: If the battery is stored with no charge for an extended
period of time, it may become damaged despite the low self-
discharge and the battery capacity could be significantly re-
duced.
Leaving the battery permanently connected to the charger is
not recommended.

If a fault is detected in the
battery, two of the LEDs on
the battery charge indicator
(6) will flash. Contact an au-
thorised bicycle dealer if this
happens.
