Grr at evil batteries!!

The batteries in my mouse are running out. And it keeps stuffing up and going dead...and the scroll wheel thing only decides to work occasionally. And I can't find my other ones. I think they were eaten by the evil monster who likes to fuck up peoples lives just for the fun of it. And of course I can't use my rechargeable batteries, because they're only 1.2v and I need 1.5v. GRRRRR!!!
