A camcorder's power system is made up of an AC power supply, a battery charger and batteries. The camera's AC power supply guarantees uninterrupted power and is a good choice when shooting in a studio or at a concert. Batteries On location, rechargeable batteries are usually used to power the camcorder.
Most camcorders utilize small, light batteries.
Some of these newer batteries provide more power than NiCads and do not suffer from memory effects. Working with Batteries Charging the camera batteries the day before a shoot is usually a good habit to develop. If renting a camcorder, make sure the rental house supplies freshly charged batteries when you pick up the camera. Unless you are lucky enough to have a lot of charged batteries, try to find a place on location where you can plug in your charger and recharge drained batteries as you shoot. A professional cameraman knows the condition of every single battery when shooting.
