Costco brand (Kirkland) AA's cost half of what Duracells cost
and last longer. I know it's hard to believe but it's true.

Rechargeables (a REAL brand, not some no-name crap) are a MUCH
better option and will cost you hundreds of dollars less in the
long run. But it's your money and your choice.

While it will give you a cable, just a different one, which will
not be attached to your computer but to wherever you want,
another option to perhaps consider is to buy a 3V AC adapter for
five dollars and have someone solder the wire into your mouse -
or do it yourself if you know how. Those things use less AC
power in a year than a lightbulb does in a few days (more or
less, no arguments "you know who you are" please) and you would
never have to worry about batteries again.

I know this is just my opinion and you don't care, but I never
saw much point in wireless m/k's unless you have a 40 inch LCD
monitor 10 feet away and like to compute from your bed. Even
then, the AC adapter cable going into the mouse would not impede
you from doing that since it can be plugged in anywhere.

There are also extension cables for both keyboards and mice and
everything else.
