Query: Eats batteries

The time worked great for a week, then it read 'low' battery. I figured I put a bad battery in it so I changed it. Again, it only worked for a week before the 'low' battery came up again. Put in a different brand of battery, same thing. Went out and bought new batteries for the 4th try, again it only lasted a week. Very disappointing, and more expensive than the brand I usually buy.
