Most people know that they need camera batteries for their camera to function. However, with the numerous features that modern digital cameras come with, battery run times keep decreasing. Some of the features that deplete battery charge include the liquid crystal displays, the camera's image storing system, the flash, the exposure system and more. The moment your camera starts to behave sluggishly, chances are you need to replace or recharge your camera batteries before they completely run out. Here are some of the different camera batteries you could find in the market if you are looking to purchase new ones.

NiMH camera batteries

These are the most common option for people who require rechargeable AA batteries for their camera. One of the greatest advantages of these batteries is that they are non-toxic. This makes them an environmentally friendly option. Additionally, since they are rechargeable, you will not be throwing them out and replacing them, thus reducing your impact on the environment. Although the purchase price of these batteries may seem a bit high, they are actually a good investment, because, as aforementioned, you will not have to keep buying batteries. However, it should be noted that the more charge and discharge cycles that they have, the less charge they will be able to sustain. As such, with extended use they will eventually have to be replaced. It should be noted that to keep you rechargeable camera batteries at optimum, you should only charge them after they have completely run out of power rather than recharging them on a regular basis. This is because topping off the charge heats the chemicals that are found in the rechargeable batteries casing. This eventually causes the reduction in their longevity.

Li-ion camera batteries

Li-ion refers to batteries composed of lithium ion. These are commonly referred to as battery packs and are the main source of power in an array of modern digital cameras. These battery packs are rechargeable and will have a case they are secured to for direct recharging from a power socket. Lithium ion camera batteries are also preferred due to their long shelf life, meaning you do not have to keep purchasing batteries for your camera. However, it should be noted that these batteries also pose a risk of leaking especially if not stored in a cool and dry place. As such, if you are not using your camera, it is best to take the Li-ion battery pack out and put it in storage until the next time you plan to use your camera.
