The Sony digital cameras fit into this class. You usually get one cell with your new camera, but it is wise to carry a second cell if the first one discharges. Don't get caught without a spare. You may be surprised at the cost of some of these cells, but usually the more they cost, the longer they will hold an acceptable charge. We have had some Sony cells for four years, and they are still operating at full capacity.
Some cameras allow for recharging while they are in the camera.
Others require removal from the camera for recharging. Click on the images below to view a movie which will demonstrate how the cells are recharged or replaced. To stop the movie, click on it again. Some camera manufacturers produce a disposable battery which can be used in their cameras. We do not recommend single use batteries.
