In the era of cameras that used films, the batteries were not very crucial as the lasted for a long time. But with the advent of digital cameras, batteries are becoming very crucial and a drained battery can spoil the day for you. For those who shoot wildlife and birds, the use of burst or taking many shots is very important. This means that their batteries must have a long life. There are different types of batteries and they all have different charging needs. Let have a look at the below in details individually

• Alkaline Batteries
• Nickel Cadmium Batteries
• Lithium Batteries
• Lithium-Ion Batteries
• Battery packs

Alkaline Batteries

These are very commonly used in cameras. These are not chargeable, and you have to just discard them once the power is drained off. This is good for occasional photographers. If you leave the batteries in the camera without using them, they can even last for up to 2 years.

Nickel Cadmium Batteries

They are the most economical types of chargeable batteries. They can be purchased with different capacities. The power is mentioned as mAh. Where the batteries have a higher mAh rating, they will give a longer life. These batteries are good for your digital cameras. But if you leave these in your cameras without using, their power will drain off over time.

The Nickel-Cadmium batteries have a problem. They must be fully discharged before you recharge them. Otherwise, they can lose their power over time. They become useless after some time. The trick is to buy a charger that will discharge the batteries fully before recharging them. Such chargers are costly but are worth the money if you want to save your batteries.

Lithium Batteries

These are non-chargeable batteries. But they come with high power and these batteries can last as long as ten years if left in the camera without using. There are four varieties of Lithium batteries and the 6V2CR5 is the common model used in your SLRs. The smaller SLRs will use the 3V123A batteries.

Lithium-Ion Batteries

These batteries are light and have high power like Lithium batteries. But these are chargeable batteries. They are being used currently in many of the digital cameras because of their small size and rechargeable nature. Different camera makers use these batteries of different sizes. When you buy your chargers for these batteries you must consider this and buy the right chargers.

Battery Packs

These are another option for digital camera users who will need power on the go. These packs carry a lot of power and will last longer. They can be connected to the camera as an external power source. You must check whether your cameras can use these power packs.
