Laptop accessories market can be described as complex

, especially laptop battery This is a counterfeit factory refurbished, old batteries, no name and address, warranty has become an empty and so endless. So how do we buy a laptop battery?

First like to say that the battery warranty period, the battery market, we see there are many, the warranty period can be divided into several, such as three months, six months a year and so on. We say that the warranty for use in a year's product is Grade A raw materials, notebook battery R & D experience, improve quality control and process, such cells are generally genuine. Almost three months or six months have one thing in common, that is, neither the manufacturer, address, telephone number, neither the protection nor the scope of protection, so the SAMSUNG 305V4A Battery most of the power of the demolition waste battery recycling core and protection board, and even some do not even have to protect the board are not very low cost, very dangerous to use, consumers' rights can not be guaranteed.

Secondly to say is that users try not to buy the compatible battery, although compatible battery is cheap, and will soon be able to get, but the risk also exists, for example, compatibility issues, the quality of the battery too, but off. So I still recommend to buy the original battery, quality guaranteed, although the price is too high, but the user is also assured bought after, if some users are reluctant to buy the original battery, then buy a adapter or UPS uninterruptible power supply.

The nominal battery capacity and the actual capacity of the signs above the notebook battery, usually marked

Note the battery's capacity, such as 3600mAh and so on, this is what we call the nominal capacity.

Is this a nominal capacity of the actual capacity laptop battery does? The answer of course is no.

As the laptop battery is always more satellites by the batteries in series parallel approach by a combination of different characteristics of batteries are always different, so the actual battery capacity depends largely on the batteries with group status.

The following chart is an example that a battery, 14.8V means four strings, 3600mAh means two and so this should be a battery specifications 3.7V/1800mAh by the eight four series of two SAMSUNG 305V5A Battery and a combination. This eight batteries of capacity may range between 1750-1850 and eventually the actual capacity of the battery pack is likely to fluctuate in the 3600mAh, but more often downward fluctuations.

In general, a new laptop battery last a little different such as a 200 mAh, the user's actual use of no effect, the user can not feel it. Formal manufacturing control standards generally over 97% of nominal capacity. A Case Study for more than just meet or exceed 3500mAh capacity and there is no charge or discharge protection can protect the factory. The factory will be difficult without formal spoke. Or the example above, if using 1500mAh batteries, the cost will be more than halved, the final capacity of 3000mAh or so, in fact, difficult to sense the user charge or discharge protection can protect the factory.

The factory will be difficult without formal spoke. Or the example above, if using 1500mAh batteries, the cost will be more than halved, the final capacity of 3000mAh or so, in fact, the user can hardly be felt. What is more, some manufacturers to use less material means to deceive the user, as shown in this more often of a current A20M SAMSUNG 305V7A Battery specifications are 10.8V/5400mAh, should use 9 10.8V/1800mAh batteries, while the market were flooded with a lot just by six batteries of inferior products, capacity up to 3600mAh, the plate is still marked 5400mAh.
