I ended up deciding that I was better off using alkaline batteries (which last for a month in the mouse and four months in the keyboard)


I've got a wired (Microsoft) keyboard, and a Logitech cordless mouse on my PC at work.

I've no idea what the USB dongle uses to talk to the mouse, but it's probably not Bluetooth -- the range is pretty poor: I have to plug it into the USB port on the keyboard, because it doesn't work too well through the desk.

However, I do get around 3 months use out of a pair of AA alkaline batteries...
