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. There are many reviews and articles telling us how to choose a decent digital camera, however, few of them tell us how to pick a replacement battery methodically and clearly. Now, let's face the important question, how can we find a good battery replacement for our digital cameras?
In this article, I will show you:
We must know batteries first before we choose one. There are 3 kinds of digital camera batteries that we often use, including: 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.
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.
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.
How to choose batteries.
For AA battery digital camera users, if you need batteries temporarily, choose alkaline battery instead. It is cheap and good enough, you can find it in every retail stores. For those regular users of AA battery digital camera, you should choose Ni-MH rechargeable battery. Though it will cost more than purchasing alkaline battery, its ability to recharge will save you a lot of money.
Many people will neglect the voltage of the battery when they plan to buy batteries. Take the two batteries into example.
Battery A: 3.6 V * 1200 mA
Battery B: 7.2 V * 1000 mA
Most people will chose battery A, but I suggest you the battery B, even though 1200 mA is higher than 1000 mA, the voltage of battery B is twice higher than the voltage of battery A. Ignore the electricity resistance,
P (power)=U (voltage)*I (current)
The power of battery B is much higher than battery A.
If your digital camera uses lithium-ion battery, the easiest way is to buy another original battery pack from the manufacture. Despite it is expensive, the quality is guaranteed and it will be full compatible with your digital camera.

Of all the innovation that paved the way to the rise of electric RC flying, battery technology plays one of the biggest roles. Today, modern batteries have a much better power-to-weight ratio than before. This allows RC airplanes and helicopters to stay in the air for a lengthy period of time - even as long as their nitro counter parts, or even longer. Amongst the types of batteries, Li-Po or Lithium Polymer rates as the best your money can buy. While they cost much less than they used to, it is always wise to make sure that your Li-Po battery will last for as long as it could. This article will provide some pointers as to how to store your Li-Po battery for long periods without sacrificing its overall lifetime.
If the Li-Po battery is brand new and you decide to keep it for a while before putting it to first use, contrary to common sense, it is best not to store the battery in its uncharged state. The best practice is to fully charge it and maintain it at 4.2 V per cell before storing the battery away for a long time. For example, if you bought a 3-Cell Li-Po battery rated at 11.1 V when fully charged, the battery will hold 12.6 V. This will make it suitable to keep stored away for 3 to 6 months. However, after 6 months, the voltage will start to weaken. When this happens, fully charge it again, whereby giving another 6 months of storage time. While this procedure can be performed over and over, the battery shouldn't be kept without being used for more than 2 years.
If the Li-Po battery is fairly new and has been used no more than 70 times, has never reached temperature of more than 45 degrees, and never short circuited, the individual cells within the battery need to be balanced before storage. This easily can be done through new versions of charger which has a "balance cell" function. Another method is to measure the voltage of each cell and set each cell to have an equal voltage to the least-voltage cell. The cells can be discharged using a simple-circuit light bulb making contact with individual cells, whereby slowly draining out each one. Once the cells are balanced, fully charge the battery, which will give each cell about 4.2 V. By doing this, the battery will be ready for a 2 to 4 month-long storage, upon which time the procedure must be repeated. Please note that ultimately, batteries of this condition stored using this procedure should not be kept for more than 1 year.
For batteries that are in a sorry state, such as having been used more than 70 times and have reached temperature higher than 60 degrees and has been short-circuited plenty of times, the first thing to keep in mind is to not hope for much. The procedure for storing these batteries still remains the same as the procedure above. Balance the cells first then charge the battery fully before storage. However, the result won't be great.
As for the storage, keep the battery in a zip-locked bag and place it in a padded aluminum or stainless container (such as a cookie box). Keep the box away from sunlight and humidity. The reason for the stainless box is to protect your house from the fire which may be ignited by batteries short-circuiting. Better safe than sorry right?
