If the battery is full it does that. What tells us the camera is without fault?
As to the replacements, go back to the shop and exchange it.

My wife has a Lumix camera, Panasonic DMC-fs5. the battery went dead, so she put the battery in the charger, the green light on the charger came on, 60 seconds later the light went out and quit charging. I bought a new charger and battery, plug in in, light went on, charged 60 seconds, and light went out, just like the other charger did, does not seem logical that the new battery and charger would both be bad, appreciate any help with this, thanks, George.
