Behavior of the ADN-W BA battery pack during charging
When charging the battery pack using the NT 12-50C power supply or the ADN-W

ers, the battery pack and the corresponding char-
ger will get warm. The battery status indicator and the charge status display
indicate the charging process:
Charging may take longer if the temperature of the battery pack is below 10°C or
over 45°C. In this case, in order to protect the battery pack, the charging process is
interrupted until the temperature is again within the admissible range and the bat-
tery status indicator lights up orange. The charging process starts automati-
cally.
