I bought this camera back in August for a vacation trip. In total I believe it wasn't used for more than 3 hours tops.Since I took plenty of batteries these have not seen more than 1 charge, maybe one or two of them got charged a second time. So they are in like new shape.
Included: Diving Case ($50 cost) (you need this if you want perfectly clear video underwater, the one that comes with the camera is waterproof, however due to the curved lens the video underwater takes a huge hit in clarity, look at youtube videos) 5 Batteries, wall charger, Tripod mount (bought separately,) several sticky mounts to attach to helmet or other flat surfaces, Car Mount, outdoor back door and floaty back door.
