Checking the battery before its rst use
Check the battery before you charge it or use it
with your e-bike for the rst time.
Press the A4 on/off button to switch on the bat-
tery. The battery may be damaged when no LED
on the charge status indicator A3 lights up. If
at least one (but not all) of the LEDs is lit in the
A3 charge level indicator, then you need to fully
charge the battery before use.
The battery may not be recharged when
it indicates a fault. The battery might be
damaged after being dropped or due to
mechanical impact, even when there is
no visible external damage. Such batter-
ies must therefore be inspected by a
FLYER specialist retailer. Never try to
open a battery or to repair it.

5.3 Loading the battery
Do not connect the charger to the mains
socket immediately after a sudden tem-
perature change from cold to warm. It is
possible that condensed water has col-
lected on the contacts and this will lead
to a short circuit. Do not connect the
battery to the charger immediately after
a sudden temperature change from
cold to warm. Wait until both devices
have reached room temperature before
connecting the charger or the battery.
Always charge and store the battery
and the charger in a dry and clean envi-
ronment.
Use only the original Bosch charger
supplied along with your e-bike. Only
this charger is designed for the lithium-
ion battery used on your e-bike.
Completely charge the battery using the
charger before the rst ride to ensure full
battery performance. Read and adhere
to the operating instructions for the
charger when loading the battery.
The battery can at any time be charged outside
or installed in the bicycle without reducing its life
span. Interrupting the charging process does not
damage the battery.
The battery is equipped with a temperature moni-
tor that permits charging only within a tempera-
ture range of 0 °C to 40 °C. Three of the charging
status indicator LEDs will ash when the battery is
outside the charging temperature range A3.
