Here is the short information for bateries:Alkaline
Alkaline batteries come in all standard sizes. If your camera uses a standard sized battery, it’s probably AA. Alkaline batteries in cameras used with a flash last only a few photos. This is an expensive solution for frequent use.
Lithium
Disposable batteries. These may be called “photo batteries.” They last well but are very expensive. The are available in most formats.
Nickel Cadmium Rechargeable.
These must be fully discharged before recharging to avoid “charge memory” and poor performance. Be careful not to overcharge.
NiMH
(Nickel-Metal Nickel-Metal Hydride are excellent batteries and are rechargeable. Hydride) These are the best value. They come in all standard sizes. Many proprietary batteries used in digital cameras are NiMH. These are powerful batteries and last about 400 charges.
Lion
(Lithium Ion) Lithium ion batteries are a good choice. They don’t have “charge memory” and they last twice as long as NiMH batteries. These are usually after-market optional batteries and are purchased as extras. These are newer and not as widely available. They last about 400 charges.
External battery
You can power some cameras through the AC power socket using packs external battery packs. These come in many of the previous formats. These can be much larger with greater storage capacity. Clip them to your belt with a wire running to the camera. These are great on vacations or long shoots like weddings.
More expensive cameras may use proprietary batteries rather than standard AA, AAA, and so on. This means that you must purchase the manufacturers’ batteries or after-market batteries designed for your camera when you need extras or replacements.
