When I recently installed my wireless mouse, I didn't know batteries only lasted a couple of weeks. I was expecting much "Mo Use" out of the mouse. Is this about normal or does it depend on the manufacturer?
I went thru batteries on my Microsoft Wireless IntelliMouse Explorer 2.0 like a boat of sailors thru a Bangkok whorehouse.
I don't believe that this is "normal" because I returned the mouse to Microsoft under warranty after a year or so and they sent me a brand new mouse.
I am still on my same set of batteries, and I have had the new mouse for many many months now. Very happy camper!
The old unit had a loose metal connection where the end of the batteries make contact inside the battery tray. I believe that this shorted-out the battery prematurely. You might wish to check for the same issue.
