The Battery World - Types and Applications (Conclusion)
The invention of battery brought convenience and efficiency to modern life. You can even guesstimate a country's technology adaptation from the amount of batteries used by that country. The advancements in battery technology leads to new types of batteries with electrical characteristics to better suit the needs of modern high-tech electronic devices. Also, they are more environmental friendly to our modern society. Many countries are either phasing out batteries that are hazardous to our environment or putting more emphasis on recycling them for the sake of nature. Perhaps cars won't be driven by gasoline powered engines in the near future, instead, they may be driven by fuel cell battery powered motors that only utilize hydrogen and air as their main source of energy. One thing is certain, battery and modern human life will have inseparable relationship in the world of future technological advancement

4 tips to extend the life of your laptop battery
Don't even think about it," my laptop screen flashed back at me contemptuously (I'm paraphrasing the error message a little here). "I'm out of juice."
And then, before I could find an electrical outlet — Sea Tac has recently increased the number of available outlets, by the way; finally a reprieve for business travelers whose budget for airline club membership has been cut — the laptop expired.
The irony, of course, is that I had spent most of the previous week researching this column on how to extend your PC's battery life while you're on the road.
In a 2002 survey by chipmaker Intel, 57% of laptop users said they wished their batteries lasted longer. And that is wishful thinking, according to Isidor Buchmann, president and founder of Cadex Electronics in Vancouver, B.C., Canada. He suggests that although batteries become about 10% more efficient every year, the average PC's power needs also increase by about the same amount. Result: The average battery life is still painfully short (just three to four hours for most laptop models).
But you don't have to end up sitting in a waiting area, staring at a darkened screen, like I was. Here are four tried-and-true tips to extend the life of your laptop battery. Why should you take advice from a guy who couldn't keep his own unit charged? Read on if you want to hear my sad excuse.
1.
Power down all nonessential functions. Switch it off if you're not using it. Many business travelers already know that you don't want to take the DVD player for a spin on the plane, and that every time you hit "save" it can set the hard-drive whirring, which devours even more power. "But users often also forget to turn off their wireless card when they are no longer using it but are still using their computer," notes Mike Fuller, executive vice president of PC Laptops, a Sandy, Utah, laptop manufacturer. "When the wireless card is on, it still continually searches for networks." In Windows XP, click on "Power Options" in your control panel. It allows you to reduce the power consumption of any number of your computer devices or of your entire system.
2.
Stay out of extreme temperatures. The technology that powers you battery isn't terribly complicated. But it's important to understand a little bit about the chemistry behind batteries, and how that can affect your work. Specifically, temperatures can affect the performance of your battery. It's best to use (and especially charge) your batteries at room temperatures. Extreme conditions can drain your battery quickly. Also, avoid partial charges and use the battery until it is dead. Battery experts liken partial charges — and discharges — to eating a cup of lard every day. It significantly shortens your battery's life. Considering that a lithium-ion battery can explode if it's improperly used, it could also shorten your life.

Battery choices and safeguard skills
Battery choices and safeguard skills
The following options to choose batteries skills are for reference only :
Formal production factories of the cell parameters clearly marked;
Purchase batteries, the best choice of nickel-hydrogen batteries or lithium-ion batteries;
Hang batteries general use PC or PVC casing material, very strong, not easily damaged, the general means to break the cell.
Neat appearance, no superfluous burr, the external surface of a certain roughness and feel comfortable.
Batteries into the battery shafts should move around, and close integration with whole sets, and attention to the nominal voltage battery voltage to be compatible with your notebook.
To ensure that the purchase of the cell, provides good performance discharged.
Normally the thin cell, smaller capacity, the thick cell, the greater will be the capacity.
Batteries and interface options to dealers in detail about some of the batteries and interface characteristics.
If you want to extend the useful life of a cell, we must also carry out proper maintenance and preservation of cells, the following is the maintenance and preservation of Extra attention :
In order to avoid battery temperature above 60 degrees or below -20 degrees to the working environment, or the use of time and life will be shortened. Battery charging basic methods for cell characteristics vary, according to the manufacturers specifications to the methods of charging instructions.
If prolonged cell wall will be the best machine, not switch on the machine because of the gradual depletion of cell energy will be.
As a non-charging battery lithium batteries in general, such as forcibly charging will cause explosions.
Do not be mobile phone batteries together with some metal products, metal objects to prevent these contacts battery polarity, short circuit caused by the phenomenon.
If the non-use of temporary mobile phone batteries, which can be temporarily released part of electricity, but further preservation.
The lithium-ion battery itself extremely active chemical weapons, sharp response, and therefore we should not arbitrarily its demolition. If the rain, intermediary, available dry cloth away, or in the ventilation Department to dry or use hot air dryers around 40 degrees.
