Charging Procedure; Troubleshooting - Bosch 1 270 020 900 Original Instructions Manual

Charging Procedure

The charging procedure begins as soon as the
charger is connected with the battery and the
mains supply.
Note: The charging procedure is only possible
when the temperature of the battery is within
the allowable charge-temperature range.
It is possible to select between two charging
modes: Normal-charging operation "FAST" and
silent-charging operation "SLOW". In the
"SLOW" mode, the charging takes place silently.

When starting the operation of the charger, nor-
mal-charging operation is preset. To change the
charging mode, press button 29.
Use caution when touching the charger dur-
ing the charging procedure. Wear protec-
tive gloves. Especially in normal-charging op-
eration with high ambient temperatures, the
charger can heat up considerably.
Note: Pay attention that the charger is well ven-
tilated during the charging procedure and that
the ventilation openings 24 on both sides are
not clogged or contaminated.
During the charging procedure, the LEDs of
charge-control indicator 15 on the battery light
up. Each continuously lit LED is equivalent to a
charge capacity of approx. 20 %. The flashing
LED indicates the charging of the next 20 %.
The battery is completely charged when all five
LEDs of indicator 15 light up continuously. The
charge procedure is automatically ended.
Disconnect the charger from the mains supply
and the battery from the charger.
When disconnecting the battery from the charg-
er, the battery is automatically switched off.
The battery can now be inserted into the eBike.
