Q: Are rechargeable camera batteries the best?
Point-and-shoot digital cameras typically use either proprietary rechargeable camera batteries or disposable off-the-shelf batteries. Both types have some advantages.
Proprietary rechargeable camera batteries cost less to use in the long run, but, once their power is gone, your camera is useless until you can recharge. You can buy a second, backup battery, but it can cost $40 or more.
Disposable batteries typically add more bulk to the camera, and they're more expensive in the long run because they sometimes run out of power quickly, especially if you use the LCD quite a bit. However, if you're traveling and run out of power, picking up two more AA batteries at a local store is an easy process. You also can use rechargeable AA batteries.
