Bosch ALB 36 LI Notice Originale page 14

14 | English
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery
is charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Meaning of the indication elements on the
charger (AL 3620 CV/AL 3640 CV/AL 36V-20)
Rapid-charging Procedure
The rapid-charging procedure is indicated by
flashing of the green battery charge indicator.
Indication element of the battery: During the
charging procedure, the three green LEDs light up one after
the other and briefly go out. The battery is fully charged
when the three green LEDs light up continuously. The three
LEDs go out again approx. 5 minutes after the battery has
been fully charged.
Note: The rapid-charging procedure is only possible when
the battery temperature is within the allowable charging
temperature range, see section "Technical Data".
Battery charged
Continuous lighting of the green LED indic-
ator indicates that the battery is fully charged.
Additionally, a signal tone sounds for approx.
2 seconds, which acoustically indicates that the battery is
fully charged.
Afterwards, the battery can be removed for immediate use.
When the battery is not inserted, continuous lighting of the
LED indicator indicates that the mains plug is inserted in the
socket outlet and that the battery charger is ready for opera-
tion.
Battery Temperature below 0°C or above 45°C
Continuous lighting of the red LED indicator
indicates that the temperature of the battery is
not within the allowable charging temperature
range, see section "Technical Data". As soon as the allowable
charging temperature range is reached, the battery charger
automatically switches to rapid charging.
When the battery is not within the allowable temperature
range, the red battery LED lights up when inserting the bat-
tery into the battery charger.
No Charging Procedure Possible
If a different malfunction of the charging pro-
cedure is present, this will be indicated
through flashing of the red LED indicator.
The charging procedure cannot be started and the battery
cannot be charged (see section Troubleshooting).
Charging Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaning-

ful and does not indicate a technical defect of the battery
charger.
A significantly reduced working period after charging indic-
ates that the battery is used and must be replaced.
Observe the notes for disposal.
Battery Cooling (Active Air Cooling)
The fan control integrated into the charger monitors the tem-
perature of the inserted battery. When the battery temperat-
ure is above 30 °C, a fan cools down the battery to the op-
timal charging temperature. The fan generates a ventilation
sound when switched on.
If the fan is not running, the battery temperature is within the
optimum charge-temperature range or the fan is defective.
In this case, the charging time of the battery might be exten-
ded.
