❶To insert the PowerTube battery (4), place it so that its

contacts are in the lower holder of the frame.

❷Push the battery upwards until it is held by the safety

restraint (8).

❸Hold 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.

❹Always secure the battery by closing the lock (2) –

otherwise the lock may open and the battery may fall

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)

the locking mechanism(9) to the side.

❷Use the pull strap(10) to pull the battery(12) out of

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)

frame with the socket for the charging connector(5)

facing upwards until the battery clicks into place.

❷Close the locking mechanism(9), insert the key(1)

into the battery lock(2) and secure the battery. Make

ing of the axial rail(11).

❸Check that the battery is secure in all directions.

Always remove the key (1) from the lock (2) after locking it.

eBike is not in use.

Operation

Start-up

uUse only original Bosch batteries that the manufac-

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.

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

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.

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.

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.
