Charging The Battery - Bosch BDU280P Mode D'emploi

EN-34
Fitting
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 (4) to switch the
battery on. If none of the LEDs on the battery charge
indicator (3) light up, the battery may be damaged.
If at least one (but not all) of the LEDs on the battery
charge indicator (3) 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

Use only the charger included with your eBike or
u
an identical original Bosch charger. Only this
charger is compatible with your eBike's lithium-ion
battery.
Note: The battery is supplied partially charged. To
ensure 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 indi-
cator (3) will flash. Disconnect the
battery 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 green LEDs on the battery charge indicator
(3) indicate the battery's state of charge of 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 5 %, all the LEDs on
the battery charge indicator (3) 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.
Using two batteries for one eBike
(optional)
The manufacturer can also equip an eBike with two
batteries. In this case, one of the charging sockets
will not be accessible or it will have been sealed with
a sealing cap by the bicycle manufacturer. Only
charge the batteries via the charging socket that is ac-
cessible.
Never open charging sockets that have been
u
sealed by the manufacturer. Charging batteries
via a charging socket that used to be sealed may
cause irreparable damage.
If you want to use an eBike that is designed for two
batteries with only one battery, cover the contacts of
the unused socket using the cover (10) provided.
Otherwise there is a risk that the exposed contacts
will cause a short circuit (see figures A and B).
