resets the "accumulation state" of the accumulators): older or
long stored batteries are being refreshed.)
The single charging level bar
flashes alternatively in
lower 2 level bar: A deeply
discharged battery is being gently
recharged with a reduced current.
The single charging level bar
flashes and add up with
solid bar: The batteries are being
charged with the maximum charge
current.
The all charging level bar
become to solid bar: The bat-
teries are fully charged and the
product has switched to trickle
charge.
Calculating the average charging time
Depending on the type, age and remaining charge in the bat-
teries, the charging process can take various lengths of time.
The average charge time can be calculated using the follow-
ing 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 product (mA)
Automatic charging control/Retention charging
This product controls the charging time for Ni-MH and Ni-Cd
rechargeable batteries separately.
This control is based on the –Δ V ("Minus Delta V") calculation.
In mathematics, with Delta Δ differences are indicated. In this
case, "Minus Delta V" means a negative voltage difference.
This charge identification makes itself useful in the following
effects: Should a rechargeable battery be charged with a con-
stant current, its voltage rises continuously. When a rechargea-
ble battery is full, its voltage reaches a maximum but falls again
slightly with further current flow. This light fall in voltage is rec-
ognised by the charging electronics and the charge process is
terminated. The product 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 selfdischarge and the batteries are kept in
a state of full charge.
Timer control
In addition, this product has a timer control which automatically
switches over to retention charging after 17 hours. This serves
as an additional protection against overcharging should the
charge termination not respond due to a possibly defective re-
chargeable battery.
Cleaning and care
DANGER! Always remove the plug before cleaning the
product. There is the risk of an electric shock!
