Stupid Batteries

So, sometimes I do something that really makes me question my brain cells. I have been trying to charge these batteries all summer. I charged them overnight, put them in the camera (my little point and shoot work camera) and it said the batteries are dead. So then I charged them all week. Same problem. Then I switched the outlet the charger was plugged into. Still they wouldn't charge. I took them home and tried again. I took them back to work. And then resorted to putting regular batteries in the camera as I needed to use it and the batteries have sat in the charger all month. THEN yesterday I realized they are not rechargeable batteries! Sometimes I am not too bright. But in my defense the batteries CAME with the camera and the camera came with the battery recharger SO wouldn't one assume the batteries would be rechargeable?
