Well whenever i put the battery to charge, the LED light doesnt stay red, instead it just blinks on and off, and the battery never charges, i own a CASIO Exilim 7.2 mega pixels.
i would bet it is the charger. Casio cameras have shorts in them very rarely but it does happen. and when it does it is most likely with the charger.
when you faced at this kind of problem then you have to take reviews from camera's experts or any other photographer. try this source http://alatest.com/reviews/digital-compact-camera-reviews/c3-147/ i am not sure but i give some hope from this source because on this site i got many experts reviews before buying digital camera. i hope u can also find solution from this source experts.
Exactly the same as with a phone... try a new charger.. if that's no good, try a new battery.. if still the same problem then it must be a fault in the charging circuitry of the camera..... simple logical fault finding.... oh.. I forgot.. it's the 21st century.. brains not required.
I can't say surely whether the problem is related to the charger or the battery as I am not so tech savvy. But I think you may seek help from http://www.supportonclick.com. My friend had faced a lot of problem with his brand new canon digital camera few days ago. I had given him the same suggestion. As he followed my suggestion his problem was solved immediately.
