We must know the battery first before choosing one. There are three types of digital camera batteries that we often use, including: alkaline battery, Ni-MH battery and lithium-ion batteries.

1.Alkaline battery

Batteries alkaline batteries are common in our daily lives. There are many brands of alkaline batteries may be found, such as Duracell, Energizer, Sony, Samsung, Maxell, etc. In contrast, alkaline batteries can not use cycle. Once it is dry, you have a choice but to throw it out.

Advantages: easy to buy cheap (who need only temporary), a great choice of products.

Disadvantages: Irrechargeable, very expensive if you frequently use. Low energy conversion efficiency.

Two Ni-MH battery

Ni-MH battery is a type of rechargeable battery. You can get to the shops in the AA size. Just as alkaline batteries, Ni-MH batteries are not expensive, either, and the voltage and performance is similar to standard alkaline batteries in these sizes. You can pay more money when buying alkaline batteries Ni-MH battery, however, the ability to recharge 1000 times can save a lot of money.

Advantage: Rechargeable, Head Compatibility

Disadvantages: His durability is less alkaline battery, which has the same specifications. Very expensive if used only once. Memory effect causes them to hold less and less of the cost.

Three Lithium-ion battery

Polymer Lithium ion Battery (sometimes abbreviated Li-ion batteries) are also charging. Today, most digital cameras use lithium-ion battery as power supply. It is lighter and stronger than alkaline batteries and Ni-MH batteries. Lithium-ion batteries have no memory effect suffering from. They also have low self-discharge rate of 5% per month. (What is 30% of NI-MH batteries).

Advantage: Rechargeable, less weight, Great Power

Disadvantages: Expensive. His life depends on the number of cycles of charge / discharge and age being produced. It is not as safe as other batteries in certain situations.
