Charge the built‑in rechargeable battery via the USB cable when needed; the mouse can be used while charging in wired mode.

Recommendations

For optimal tracking and glide, use a quality gaming mousepad and ensure the sensor and PTFE feet remain clean. Choose RF wireless for the lowest latency in competitive play, switch to Bluetooth for connecting to mobile devices, and use wired USB when charging or when absolute maximum stability is required. Calibrate sensitivity and polling settings according to your playstyle to make the most of the 42,000 DPI range and low weight.
