Ensure the battery is placed on clean surfaces
u
only. Avoid getting dirt, e.g. sand or soil, in the
charging socket and contacts in particular.
Testing the battery before using it for the
first time
Test the battery before charging it for the first time or
using it in your eBike.
To do this, press the on/off button (7) to switch the
battery on. If none of the LEDs on the battery charge
indicator (6) light up, the battery may be damaged.
If at least one (but not all) of the LEDs on the battery
charge indicator (6) 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 dam-
u
aged. Contact an authorized bicycle dealer.
Charging the battery
A Bosch eBike battery must only be charged us-
u
ing an original Bosch eBike charger.
Note: The battery is supplied partially charged. To en-
sure 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 instruc-
tions in the operating manual for the charger.
The battery can be charged at any state of charge. In-
terrupting the charging process does not damage the
battery.
The battery has a temperature monitoring function
which only allows it to be charged within a tempera-
ture range of 32 °F to 104 °F.

If the temperature of the
battery is outside this
charging range, three of
the LEDs on the battery
charge indicator (6) will
flash. Disconnect the bat-
tery from the charger and
let it acclimatize.

CAUTION
Do not connect the battery pack to the charger
u
until it has reached the allowable charging tem-
perature.
Battery charge indicator
The five LEDs on the battery charge indicator (6) indi-
cate the battery's state of charge when the battery is
switched on.
Each LED represents approximately 20% of the
charging capacity. 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 10%, the last re-
maining LED will flash.
If the battery capacity is less than 5%, all the LEDs on
the battery charge indicator (6) 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.
Inserting and removing the battery
Always switch off the battery and the eBike sys-
u
tem when inserting the battery into the holder
or removing it from the holder.
