E) Estimating The Charging Time; F) Temperature Deactivation; Maintenance And Cleaning - VOLTCRAFT IPC-3 Bedienungsanleitung

e) Estimating the charging time

The expected charging time can be roughly estimated with a calculation formula.
Multiply the rated capacity of the rechargeable battery used by 1.2 (a rechargeable battery
takes out about 1.2 times the energy that it can save). Divide this value by the set charging
current. The result is roughly the charging time.
This is only a rough estimate, since many factors such as rechargeable battery condition,
temperature, etc. will influence charging.
Example: Rechargeable battery rated capacity 1000 mAh x 1.2 = 1200 mAh
1200 mAh / 500 mA charging current = 2.4 hours

f) Temperature deactivation

The charger will automatically switch on the integrated fan at a device temperature of >40 °C.
If the fan cooling is not sufficient and the device temperature exceeds 60 °C, charging will be
interrupted. The charging current display will go down to 0 mA. Do not disconnect the charger
and let it cool off. Charging will resume automatically when an acceptable device temperature
has been reached.
If the temperature deactivation recurs, you may need to reduce the charging current.

10. MAINTENANCE AND CLEANING

Apart from occasional cleaning, the charger is maintenance-free. Ensure that the contacts at
the charger and the rechargeable batteries are always clean and free of oxide layers. Discon-
nect the device before cleaning it.
Do not use any abrasive cleaning agents or petrol, alcohol or the like to clean the product.
They will damage the surface of the device. Furthermore, the fumes are hazardous to your
health and explosive. Also do not use any sharp-edged tools, screwdrivers, metal brushes, etc.
for cleaning.
Use a clean, lint-free, antistatic, dry cloth for cleaning the device or the displays.
