Flashing red battery charge level indicator (3)
The flashing light of the red battery charge
level indicator (3) signals that the charging
process has been interrupted by a different
fault, see section "Errors – causes and correct-
ive measures".
Indications on 36 V Batteries
During the charging procedure, the three green charge-con-
trol indicators (5) of the battery light up one after the other
and briefly go out. The battery is fully charged when the
three green indicators light up continuously. After approx.
5 minutes after the battery has been fully charged, the three
green indicators go out again.
When the red temperature control indicator (6) lights up
when placing the battery into the charger, the temperature
of the battery is not within the charge-temperature range
(see section "Technical Data"). The battery cannot be
charged until after the allowable operating temperature
range has been reached.

Practical advice

When the charger is used continuously, or for several con-
secutive charge cycles without interruption, the charger may
heat up. This is, however, harmless and does not indicate
that the charger has a technical defect.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Battery cooling (Active Air Cooling)
The fan control unit integrated into the charger monitors the
temperature of the inserted battery. As soon as the battery
temperature is above approx. 0 °C, the battery will be cooled

by a fan. The fan generates a ventilation sound when
switched on.
If the fan does not run, it is defective or the battery temper-
ature is < 0 °C. This can increase the charging time.
