# 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 the charging bay (1) and the battery contacts are free of coarse dirt. Ensure that the battery is fully inserted.

The charging process begins as soon as the mains plug for the charger is inserted into the mains socket and the battery is inserted into the charging bay (1).

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.

In this way, the battery is treated with care and remains permanently fully charged when it is stored in the battery charger.

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.
