2.5 Operating principle

The Acculan® 3Ti charger GA677 has been designed for
the mains voltage range 100 V to 240 V / 50 Hz to
60 Hz.
To make the Acculan® 3Ti charger GA677 ready for
operation, connect it to the mains supply using the
mains power cord. There is no other action required to
activate or deactivate the charger.
The Acculan® 3Ti charger GA677 performs a self-test,
which takes approx. 3 seconds. During this test, all
indicator elements at the front panel of the charger are
illuminated.
The Acculan® 3Ti charger is equipped with four inde-
pendent slots for charging bays for Acculan® 3Ti
rechargeable batteries GA666 and GA676 or for charg-
ing bays for Acculan® rechargeable batteries GA646,
GA626 and GA616.
Each charging bay has an indicator field on the charger
front panel assigned to it.
Charging starts automatically as soon as a battery is
inserted in a charging bay.
The charging time in all 4 charging bays depends on
the charge state and capacity of the batteries.

Charging principle

The batteries are charged very gently with constant
current pulses.
change recom-
The charge state of the battery is continuously moni-
tored throughout charging. Monitoring of the charging
curve ensures that the battery is fully charged without
overcharging.
The battery temperature and charging time are moni-
tored, too.
The Acculan® 3Ti rechargeable batteries GA666 and
GA676 undergo an automatic battery check during
charging. This check assesses the battery condition. If
this assessment yields a negative result, the "Battery
change recommended" symbol (in the respective indi-
cator field 2) is illuminated to alert the user.
