Kompernass KH 980 instruction manual Troubleshooting, Calculating the charging time

Calculating the charging time

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 Universal Battery Charger controls the charging time for rechargable batteries of the types Ni-Cd and Ni-MH separately. This control is based on the U („minus Delta U“) calculation.

In mathematics, with Delta 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 recog- nised by the charging electronics and the charge process is terminated. The Universal Battery Charger automatically switches to „Retention charging“.

Troubleshooting

The Universal Battery Charger displays no functions

Check to see if the power cable is correctly inserted into the power socket.

Check to see if the power socket is „live“. To do this, connect a different, functioning electrical appliance to the socket.

The inserted batteries are not being charged

Check that the batteries are being inserted in accord with their polarity.

Check that batteries suitable for charging have been inserted into the Universal Battery Charger. Suitable for charging are exclusively rechargable Ni-Cd and Ni-MH batteries of the types AAA/AA/C/D and 9 V Block batteries.

Remove the power cable from the power socket and allow the appliance to cool down, as the temperature monitoring has possibly activated itself.

Other malfunctions

Make contact with one of our service partners close to you if:

the malfunction cannot be corrected as described above,

or, when operating the Universal Battery Charger, other malfunctions occur.
