For a photographer, there’s little worse than the lousy feeling that you have just missed a fantastic shot because the digital camera battery went dead. It’s required to bring another replacement battery with you if you’re planning to take a lot of pictures. There are various reviews and articles telling us how to choose a decent digital camera, however, a number of them tell us how to select a replacement battery systematically and clearly. Now, let us confront the major question, how do we find a good battery replacement for our digital cameras?
In this article, I will show you:
- 1. Batteries Classification.
- 2. How to Select batteries
- 3. Battery keeps.
We have to understand batteries before we choose one. There are 3 types of digital camera batteries which we frequently use, such as: alkaline battery, Ni-MH battery and also lithium-ion battery.
1. Alkaline battery
Alkaline battery has become the most common battery in our daily life. There are a number of manufacturers of alkaline batteries we could find, such as Duracell, Energizer, Sony, Samsung, Maxell, etc.. Unlike rechargeable batteries, alkaline batteries are not able to circulation use. When it is drained, you have no choice but throw it away.
Benefit: Easy to buy, Cheap (only for who want it ) and much 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 sort of rechargeable 18650 Battery. You may find it in retail stores in size AA. As the like alkaline batteries, Ni-MH batteries aren’t expensive, either, and the voltage and performance is similar to standard alkaline batteries in those dimensions. You will pay more money than rechargeable batteries when purchasing Ni-MH batteries, but the ability to recharge 1000 times may spare a great deal of cash.
Edge: Rechargeable, Great compatibility
Disadvantage: Its durability is much less than alkaline battery that has the exact same specification. Cost too much if use only once. The Memory effect will induce them to hold less and less charge.
3. Lithium-ion battery
Nowadays, most digital cameras use Lithium-ion battery as power supply. It is lighter and stronger than alkaline battery and Ni-MH battery. Lithium-ion batteries don’t suffer from the memory effect. They also have a low self-discharge speed of about 5% per month. (which is 30 percent for Ni-MH battery).
Its life span is determined by the amount of charge/discharge cycles and the age from being manufactured. It’s not too safe as other batteries in certain situation.
How to choose batteries.
For AA battery digital camera users, should you need batteries temporarily, choose alkaline battery instead. It is good and cheap enough, you will find it in each retail stores. For all those typical users of AA battery digital camera, you need to pick Ni-MH rechargeable batterypowered. Even though it is going to be more expensive than purchasing alkaline battery, its own capacity to recharge will save a great deal of cash.
A lot of people will fail the voltage of this battery when they plan to get batteries. Take both batteries example.
Battery A: 3.6 V * 1200 mA
Most people will chose battery A, but I suggest you the battery B, although 1200 mA is greater than 1000 mA, the voltage of battery B is twice greater than the voltage of battery A. Ignore the electricity immunity,
