Long-Term Battery Performance

The keyboard runs on two AAA batteries. The mouse uses one AA battery. Both are included. Dell states a service life of up to 36 months for the keyboard. This reduces maintenance time for IT teams and home users. You should verify the exact battery type replacement when stock runs low.

2.4 GHz Wireless Reliability

This combo uses RF wireless technology on the 2.4 GHz frequency band. It provides a stable connection up to 10 metres. Because it is not Bluetooth, you must use the included USB receiver.
