The Best Battery For Your Digital Camera

For a photographer, there is little worse than the bad feeling that you’ve just missed a fantastic shot because the digital camera battery went dead. It is necessary to bring another replacement battery with you if you are planning to take a lot of photos.

We must know batteries first before we choose one. There are 3 kinds of digital camera batteries that we often use, alkaline battery, Ni-MH battery and lithium-ion battery.

1.Alkaline battery

Alkaline battery is the most common battery in our daily life. There are many brands of alkaline batteries we can find, like Duracell, Energizer, Sony, Samsung, Maxell, etc. Unlike rechargeable batteries, alkaline batteries are not able to circulation use. Once it is drained, you have no option but throw it away.

Advantage: Easy to buy, Cheap (only for who need it temporarily,) and more choice of brands.

Disadvantage: Irrechargeable, Cost too much if often use. Low energy conversion efficiency.

2. Ni-MH battery

Ni-MH battery is a kind of rechargeable battery. You can find it in retail stores in size AA. As the same as alkaline batteries, Ni-MH batteries are not expensive, either, and the voltage and performance is similar to standard alkaline batteries in those sizes. You may pay more money than alkaline batteries when purchasing Ni-MH batteries, however, the ability to recharge 1000 times can save a lot of money.

Advantage: Rechargeable, Great compatibility

Disadvantage: Its durability is less than alkaline battery that has the same specification. Cost too much if use only once. The Memory effect will causes them to hold less and less charge.

3. Lithium-ion battery

Lithium-ion battery (sometimes abbreviated Li-ion batteries) is also rechargeable. Nowadays, most digital cameras use Lithium-ion battery as power supply. It is lighter and more powerful than alkaline battery and Ni-MH battery. Lithium-ion batteries do not suffer from the memory effect. They also have a low self-discharge rate of approximately 5% per month. (which is 30% for Ni-MH battery).

Advantage: Rechargeable, Less weight, Great energy

Disadvantage: Expensive. Its life span is dependent on the number of charge/discharge cycles and the age from being manufactured. It is not so safe as other batteries in some situation.
