My K200 indicates that the batteries have lost their power. I have tried new batteries that I know are well charged and it doesn't help.

Take a look at the battery contacts in the camera. It is possible they have become tarnished over the years especially if the camera was unused for awhile. You might try cleaning them with a pencil eraser.

Also double check you have the batteries inserted properly, I have put those AA's in wrong and thought there was a problem.

With my K200d eneloop branded batteries worked flawlessly

Had a similar problem recently with my k100 super, left with flat batteries for months...charged batteries said low almost instantly....cleaning camera contacts def sorted the problem...
