The amount of time you get out of your camcorder’s battery life depends on both the type of battery in your camcorder and how you intend to use your camcorder. Many camcorders have removable batteries; if you’re going to be shooting for a long period of time, you should always carry a few fully charged backup batteries to alleviate concerns about how long your camera will last. Your camcorder may also be equipped to use AC power—meaning that it can be plugged into a wall while shooting rather than having to maintain its own charge. If your camera has this option, and you’re shooting inside, then using AC power will allow you to shoot endlessly without having to worry about replacing batteries.
