Recently I noticed the red light on my mouse was appearing far more often than it used to. I would leave the mouse in overnight and even when it showed me there was a full charge (solid green light and then no more green light) it would turn red after maybe an hour of use. So I went to Radioshack and bought some new Ni-Mh AA's rated at 2000 MAH figuring they would work fine. When I first installed them the mouse indicated it was charging for about fifteen minutes and then the solid light went on. Confused I used my mouse as I would until the red light went on, about fifteen minutes later. I then left it in the charger overnight. Still, after only a few hours of use the mouse flashed red and then died. I'm starting to wonder if it's the base station or the mouse that is faulty and not the batteries. Anyone have any experience with problems such as these?
