Wireless mouse with longest battery life?

  My system is a year-and-a-half-old Dell Dimension 8400 running WinXP,
with a Dell wireless keyboard and mouse, and is left on 24 hours a
day. Unfortunately the mouse, which requires two AA batteries, uses up
batteries very fast, so I'd like to replace the mouse with a more
efficient one (but keep my current Dell wireless keyboard).

Which wireless mouse has the longest battery life?

I know that rechargeable batteries are an option, but would prefer to
keep using regular Duracell's, but with longer life.

 

I've got a Micosoft which shuts itself off when you don't move it, and
quick as you put some motion to it, it lights back up. It uses 2 AAA's, and
instead of the provided alkalines, I use NiCads and recharge them.


Best wishes to you and yours for a safe and joyous holiday season.

We might be so mean,

I have seen Wireless Mice where the USB receiver also doubles as a charger,
the idea being you just drop the mouse into the receiver/charger while you
are not using it
I've seen Logitec ones, not doubt there are other reputable brands.
I personally have a no name Supermarket one that has not gone flat in over a
year by just popping it into it's cradle when I not in use. (Not a
particularly good mouse though)

I have a logitech LX7 now.  It lasts way longer than other mice I have had.
It doesnt have the recharger cradle, but thats fine with me cause I always
had problems with those.  I keep a battery recharger behind my desk with 2
spare batteries topped off.  Even using the rechargeable batteries it goes
about a month of heavy usage before I swap them out.  I guess if I used
regular batteries they would last 6 months.

Depends on the application.
