I received my DC800 w/ the dual strobes a couple weeks ago and yesterday (8/27) was my first time using it underwater. I charged the rechargeable batteries overnight last weekend. When they were done charging, I left the batteries in the chargers and placed the chargers in the carrying case. When I went to use the camera yesterday, all the batteries had discharged...strobes did not work. Did I do something wrong? Should I not have stored the batteries in the chargers? Are the batteries or charger bad? Any help would be appreciated.
