My laptop's wireless mouse has used the same AAA battery for months, and it gets used regularly. It's not daily, but it's at least a few times a week for an hour, and usually a lot more.

My wired mouse on my PC gets used about the same amount, but the cable occasionally catches under the corner of the keyboard. It's not helped by the fact that I move the keyboard around depending on what I'm doing. That's also the reason I'm considering a wireless keyboard as well though.

I had a wireless keyboard where the internal battery was total crap, had to keep it plugged in because it would drain within an hour. Got one with replace batteries, plenty of those available. Might be safer bet for you as well.
