Query: Eats batteries

I bought a Pentax Optio E30 a few months ago. After taking a few pictures (10-15) I had to replace the batteries. The new batteries lasted only 2-3 days and I only used the camera for less than an hour. I bought a charger and some rechargeable Ni-Mh batteries. They don't fare any better than the alkaline. I very seldom use this camera and the batteries go dead just sitting in the camera for 2 to 4 weeks. I would not recommend this camera to anyone I liked.
