Practical advice

When the charger is used continuously, or for several consecutive 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 indicates that the battery has de-
teriorated and must be replaced.
Battery Cooling (Active Air Cooling) (AL 1880 CV)
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 temperature is < 0 °C. This can in-
crease the charging time.
