A significantly reduced operating period after charg-
ing indicates that the battery pack is worn out and
must be replaced. You can replace it yourself by pur-
chasing a genuine Bosch PowerPack from an autho-
rized Bosch eBike dealer.
Recharging the battery before and during
storage
When you are not going to use the battery for an ex-
tended 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
(3) are lit).
Check the state of charge after six months. If only one
of the LEDs on the battery charge indicator (3) is lit,
charge the battery back up to around 30 % to 60 %.
Note: If the battery is stored with no charge for an ex-
tended period of time, it may become damaged de-
spite the low self-discharge and the battery capacity
could be significantly reduced.
Leaving the battery permanently connected to the
charger is not recommended.
Storage conditions
If possible, store the battery in a dry, well-ventilated
place. Protect it against moisture and water. When
the weather conditions are bad, it is advisable to re-
move the battery from the eBike and store it in a
closed room until you use it next, for example.
Store the eBike batteries in the following locations:
– In a room with a smoke alarm
– Away from combustible or easily flammable objects
– Away from heat sources
For an optimum service life, store the eBike battery at
temperatures between 50 °F and 68 °F. Never store
it at temperatures below 14 °F or above 140 °F.
Make sure that the maximum storage temperature is
not exceeded. Do not leave the battery in your car in
the summer, for example, and store it away from di-
rect sunlight.
Leaving the battery on the bicycle for storage is not
recommended.
