I've got a Logitech wireless keyboard/mice combo, but it runs on normal 2 normal batteries each.
With very heavy usage the mouse kills Duracell batteries in 1.5-2 months, but cheap batts in 3-4 weeks.
I complained to Logitech's Tech support and they said that if you use the mouse on a BLACK/semi-reflective surface it will improve life.
The keyboard lasts close to six months on fresh batts.
But I usually take the dead one's out of the mouse and put them in the keyboard. With those the keyboard will usually outlast the new batteries I replaced them with than the mouse.
