One Month Battery Life MS Wireless Mobile Mouse 4000

I purchased this mouse a few months ago, and use it daily.  I'm very happy with the performance, but not with the battery life.

I am forced to replace the battery every month, almost to the day.

The mouse is used primarily with my desktop system, both in my web development work, and general usage.  I estimate my active use at 8 hours daily, but my systems are powered on all the time.

I have used new name brand alkaline batteries (Energizer, Duracell) and the last 2 months, Energizer Lithium batteries, with no difference.

It's impractical for me to turn the mouse on and off throughout the day.

The packaging claims up to 10 months of battery life - obviously I'm not getting anywhere near that.

I have the latest intellipoint drivers and otherwise my Win 7/64 system is up to date.

Do you have any ideas why I'm having this issue, and what I might be able to do about it?

Thanks in advance - as I said, I love the mouse, but the battery costs are eating me alive!

Have you tried contacting MS support about getting it exchanged/replaced? How about the place you bought it? I've had a few wireless mice, and their batteries have all lasted longer than a month, but only one has lasted as long as 10 months. I have a MS Natural Wireless Laser 6000 that they last 6 months, almost to the day. But the batteries in my Logitech V470 Bluetooth Notebook mouse last about 4 months, and it's turned off more than on.
I think you have a defective mouse, but I'm sure neither your merchant nor Microsoft would take my word for it :-)
