Charging process
- Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the charger.
- Ensure that all charging bays (1) and charging contacts are free of coarse dirt. Ensure that all rechargeable batteries are fully inserted.
The charging process begins as soon as both the mains plug and a rechargeable battery have been inserted. If the charging process is started with multiple rechargeable batteries simultaneously, they will be charged one after the other in the direction of the imprinted arrows (2) (anticlockwise).
The rechargeable batteries are charged one after the other in two charging cycles.
- In the first charging cycle, all inserted batteries are charged up to approx. 80 % of their capacity.
- In the second charging cycle, the rechargeable battery is charged from approx. 80 % to full capacity. The second charging cycle begins when all inserted batteries have been charged to approx. 80 %.
If the rechargeable battery has a state of charge of over approx. 80 %, it is skipped during the first charging cycle and charged in the second charging cycle until it is charged to full capacity. If a new rechargeable battery with a state of charge below approx. 80 % is inserted during the second charging cycle, it is charged immediately. Once this rechargeable battery has been charged to approx. 80 %, the charging sequence is redefined. The next rechargeable battery that is charged in the second charging cycle follows the sequence of arrows (2) on the charger (anticlockwise).
- The charging process is only possible when the temperature of the battery is within the permitted charging temperature range (0–45 °C).
Thanks to the intelligent charging process, the state of charge of the battery is automatically detected and then charged up with the optimal charge current depending on battery temperature and voltage.
A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced.
When the charger is used continuously, or for several consecutive charge cycles without interruption, the charger may heat up. This is, however, harmless and does not indicate that the charger has a technical defect.
