Play with confidence. The G602 sticks by you through game after game with up to 250 hours of power in Performance mode. That's as much as eight times the battery life of other wireless gaming mice, all without compromising the gaming-grade sensor and connection performance. The G602 is powered by two standard AA batteries; optionally remove one battery to adjust its weight and balance. The G602 delivers a lag-free experience through a 2.4GHz wireless connection with a two-millisecond report rate. Unlike Logitech Unifying receivers meant to connect multiple devices, G602 uses the entire bandwidth of a dedicated USB nano receiver for gaming-grade, low-latency performance. Position the nano receiver for optimal reception using the included extender cable. A convenient storage slot in the battery compartment keeps the nano receiver safe for transport.
