The charging process now begins. The battery charger has an LED for each
compartment in the charging slot. The LEDs of the respective charging slots
show the charge status of the individual batteries. In addition, the current
charge status of each battery is shown as a percentage on the display

If the LED on the charging slot blinks red for longer than 5 seconds, the
battery is either improperly inserted into the loading slot or it is defective.
Operating status displays
The various displays have the following meanings:
■
The LED flashes red and green once per second: The batteries are being
alternately charged and discharged. (Refresh-Function: older or long stored
batteries are being refreshed.)
■
The LED flashes green once per second: A deeply discharged battery is be-
ing gently recharged with a reduced current.
■
The LED glows constantly red: The batteries are being charged with the maxi-
mum charge current.
■
The LED glows constantly green: The batteries are fully charged and the bat-
tery charger has switched to trickle charge.
In addition, the current charge status of each battery is shown as a percentage
on the display

Calculating the average charging time
Depending on the type, age and remaining charge in the batteries, the charging
process can take various lengths of time. The average charge time can be cal-
culated using the following formula. Take note however that the times given are
only guiding values.
Charging Time (min) = Battery capacity (mAh) x 1.4 x 60
Charging current of the device (mA)
Automatic charging control / retention charging
This battery charger controls the charging time for batteries of the types Ni-Cd
and Ni-MH separately. This control is based on the –Δ U ("minus Delta U")
calculation. In mathematics, with Delta Δ differences are indicated. In this case,
"Minus Delta U" means a negative voltage difference.
This charge identification makes itself useful in the following effects: Should a
battery be charged with a constant current, its voltage rises continuously. When
a battery is full, its voltage reaches a maximum but falls again slightly with further
current flow. This light fall in voltage is recognised by the charging electronics
and the charge process is terminated. The battery charger automatically switches
to "Retention charging". This means that the batteries are no longer being loaded
with constant current, instead, with short current pulses. This counteracts the self-
discharge and the batteries are kept in a state of full charge.
