How long is a laptop battery's standby time?

It's no doubt that the standby time of laptop battery is one of the topics which the vast number of notebook computer owners are the most concerned. Well, here let's talk about something about laptop battery's standby time.

The capacity of laptop batteries and other rechargeable batteries is maeked as xxxx mAh on the surface of batteries. Such as 3000 mAh, that the battery pack 3000 milliamperes of electricity, if the battery-powered equipment (notebook computers) need to work on average current of 1 Amp, or 1000mA, this battery can work about three hours, if equipment, the average operating current is 2 amps, the battery can work about 1.5 hours. (This ignores the depletion of the battery itself)

Many clients often ask us some question about "laptop battery's standby time ". Actually, this is a question very difficult to answer accurately, as previously described: the working hours of battery is desided by the output current of laptop. It means, big output current, short working hours. In general, different brands, different models, different output current. When running diferent programs or different working methods, such as reading and writing hard disk, floppy disk, CD-ROM in time, the bright LCD screen extent, resulting in the operating current is not the same. The most important thing is how to define "standby", it seems there is no clear definition, we can not explain to you clear that does it mean running operating system without other programs ? Or shut down to protect the screen?

It's significative at a certain degree to test different batteries by using the same laptop, working in the same manner, but this is not the only measure of battery performance indicators.
