The various indicators have the following meanings:
-
The LED blinks alternatively red and green:
The batteries are being charged and discharged
alternately. (Refresh function: With this, older
batteries or batteries that have been stored for a
long time will be refreshed.)
-
The LED blinks green:
The batteries are being charged by a battery-
preserving impulse charge.
-
The LED continuously glows red:
The batteries are being charged with the maximum
charge current.
-
The LED continuously glows green:
The batteries are fully charged and the Battery
Charger has switched to a trickle charge.
Notice:
Should Type C or D batteries be charged in the outer
charging slots, the operating condition is displayed
by the respective outer LEDs.
Warning!
The batteries could become hot during charging.
NEVER touch hot batteries! There is a danger of
being burnt!
• Remove the power cable of the Battery Charger
from the plug socket and allow the batteries to
cool down.
Afterwards you can remove the charged batteries
from the Battery Charger.
Calculating the average charging time
Dependant on the type, age and remaining battery
charge, hence the charging process takes different
lengths of time. The average charging times can be
calculated using the following formula.
Note, however, that the times calculated are only
indicative.
Current time (Min.) =
Capacity of the battery (mAh) x 1,5 x 60
Charging current of the appliance (mA)
Automatic charging control/
Retention charging
This Battery Charger controls the charging time for
rechargable 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
described.
„Minus Delta U" in this case 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 the battery is
full, its voltage reaches a maximum and falls lightly
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
charged with continuous power, but with short power
impulses instead. This counteracts the process of
self-discharge, thus retaining the batteries in a fully
charged condition.
