charger is now ready for operation.
b) Available operating modes
The charger offers two different operating modes:
• “CHARGE”operatingmode
The charger starts the charging process; after completing battery charging, the charger
switches to trickle charging automatically.
• “CHARGETEST”operatingmode
The charger tests the capacity of the battery by fully charging and then discharging the bat-
tery. A charging process takes place after a break of approx. 5 minutes.
Note that setting the charging current too high can lead to the battery not being fully
charged and to large deviations between the measured battery capacity and the ca-
pacity indicated on the battery. We recommend setting a charging current approx.
1/10ofthebatterycapacity(fora2700mAhbattery,achargingcurrentof300mA).
