Types of Camera Batteries

There are several types of camera batteries on the market today. When choosing a battery for your camera, there are some factors you should consider. You will need to take into consideration how much you want to spend for batteries, how often you use your camera and how you want your camera to perform.

Alkaline

Alkaline batteries are powerful, large capacity, short term disposable batteries. Even though they do not last very long when used in a camera, they deliver a lot of energy in a short time. These batteries are inexpensive, but can become costly if you use a lot of them. Alkaline batteries are not the best choice to use in very cold weather, as the power output is reduced. If you do not use your camera very often, remove the batteries, as they will eventually self discharge, even when the camera is not turned on.

Lithium

Lithium batteries are more expensive than alkaline batteries, but they do last a lot longer with normal use. With heavy use, especially when using a flash, they have a short lifespan. When compared to alkaline batteries, lithium batteries provide more voltage at a higher rate for a longer period. These batteries can easily hold up to the brief, heavy demands of a camera.

Rechargeable

Rechargeable batteries do not have as much power or high current capabilities as alkaline batteries, but they do last longer. The number of times a rechargeable battery is charged and discharged determines the service life of the battery. Each time the charge is topped off, one of the available cycles is used up. To extend the life of a rechargeable battery, it is best to let the battery fully discharge before charging it up again. Types of rechargeable camera batteries include nickel-cadmium, nickel-metal-hydride, rechargeable alkaline and sealed lead acid. If you use rechargeable batteries, you will have to purchase a battery charger.
