Operation
Battery Quick Test
1. Plug in the power plug of the battery charger into a wall socket. After a
short self test (all charging state indicator LEDs shortly blink three times),
the device is ready for use.
2. Insert the batteries to be tested into the corresponding charging slots (refer
to “Battery Size and Specification”). To do so, pull the spring contact
backwards, insert the battery and release the spring contact. The battery
gets clamped in the charging slot; respectively insert a 9 V block battery
into the corresponding charging slot at the right side of the charger. Do not
tilt the battery and do not use force when inserting the battery.
3. Pay attention to the proper polarity of the batteries. The polarity is printed
inside the various charging slots.
4. All charging slots are operated by electric circuits which work separately
from each other in order to ensure an individual charging and testing
process of the connected batteries (individual supervision of cells). After
inserting the battery, the corresponding charging state indicator LED (3)
displays the charging state of the battery for 5 seconds as follows:
Charging State
Indicator LED Battery Charging
State
Green
≥ 80%
Orange 25% – 80%
Red
≤ 25%
Flashes Red Defective
If the charging state indicator LED (3) is flashing red directly after inserting the
battery into the charging slot, the battery is defective. This battery cannot be
charged anymore. Replace this battery and do not use it any further.
Charging Batteries
1. Five seconds after inserting the battery into the charging slot, the quick test
is finished and the charger automatically switches into charging mode. All
charging slots are controlled individually and separately from each other by
the charger’s electric circuits.
2. The battery charger automatically controls the entire charging and
refreshing process. The charging state indicator LED that refers to the
corresponding charging slot indicates the individual charging state of the
connected battery (see following table).
