How to buy laptop battery–five
3. Test battery performance
When you buy laptop batteries at the store, don't voluntarily buy a right one to take away. Battery testing is an essential part. One focus of the test is to view charge cycles, and second is the standby time. Many people think that the notebook battery use life is calculated according to fixed number of year, in fact, the decision to play the role of real factors should be fully charge and discharge times. In general, the international brands of notebook product line will be provided in the accompanying software in a management tool battery. This tool reads the battery pack through the intelligent control chip inside to see such as the use of time, the battery design capacity, actual capacity, and discharge times and other information. Through which users can understand the information whicn can not be seen in some of the surface label in the battery .

The market also has the compatible battery for sales, like "godmobi" series notebook battery use the brand notebook factory's IC chips and the design and manufacture with high quality batteries, not only have all the original battery protection, and stable performance, using a fairly long time. The actual performance is not much difference with the original battery, while the price is lower than the original battery a lot. So I think that if you are not satisfied wuth the original battery , you can buy excellent quality brand compatible batteries.
At the sane time, you must pay attention to the small workshop production of compatible batteries. The internal circuit design if this battery is extremely simple , the quality of batteries used more times, and some even use a disassemble, or no-name batteries, battery compatible with the quality of this nature is not guaranteed. In addition, after some cells of the original laptop batteries abate, a number of business change the cells to make the original battery "rebirth." However, this battery is not the true sense of the original battery, and its quality depends largely on how the quality of the cells are.

Also note the battery appearancein the purchase , generally speaking,the original battery shell mold is relatively standardized, when load it on the laptop ,it will not appear mounted to take difficult or loose situation; another, don't buy the battery whose label riting is more rough and not clear. Moreover, some posing as the renovation of the new battery cell should note that these battery electrode traces is heavy general wear and tear, gloss, and no the new battery.
II. Look at the quality of the battery
Typically, the laptop battery quality is proportional to the weight. As the original battery protection circuit are doing more monitoring in place, the quality is better , so the weight is much bigger than assembly of battery which cutting corners , try hand weights when you to purchase, if the battery wieght is lighter than many of his original words, then you need to be aware of. A while ago, Sony, Dell, Apple, Lenovo and other brands of notebook have quality problem after another, making the original battery give a bad impression.

Theoretically, the higher the value is , the battery is used longer in the same configuration . The laptop battery manufacturers are rather detailed for the battery, we can often see the "six core 4400mAh", "4 core 2200mAh" nominal value as batteries, but in fact it is not the capacity of 4400mAh, or 2200mAh which is directly determine laptop working hours. When we talk about computer power consumption, the total nominal power use, rather than simply current. To common 2200mAh, 3.6V batteries, for example, some small way may be formed by four batteries in series, the voltage is 14.4V, Capacity 2200mAh. For many 14-inch notebook, you may use 2 and 4 strings of 8-core hybrid mode, the voltage is still to 14.4V, capacity doubled to 4400mAh, ensuring a longer duration of use. However, the same is 2200mAh, 3.6V batteries, if using 2 and 3 series of 6 core of a mixed mode, the battery capacity is still to 4400mAh, voltage drops to 10.8V, If you look at capacity, its using time should be the same as the 8 core battery. If you press the power to count, 8-cell lithium battery, power should be 63.36Wh, 6 cores for 47.52Wh, 4 core for 31.68Wh. According to this value, 8-core advantage of lithium batteries can be reflected.

The laptop battery is the heart of the laptops, which is the advantage compared to the desktop. Now most of the majority of notebook battery life is 2 to 4 hours , which may be unable to meet the needs of the users. So, for those who need to move office or regular walking friends, prepare a backup battery is also very necessary. Furthermore, the laptop battery is kind of consumables, after use of one or two years ,it will be significantly decreased the performance, combined with some users not usually pay attention to battery maintenance work, the battery performance of the rapid decay and even examples of early retirement is not uncommon. How to choose a cost-effective battery is the number of users' eager to understand the problem. We will talk about the purchase of batteries.
1. Note that the parameters of the battery
Notebook battery is not all-purpose, users must understand their machines to support the battery type first before purchase the battery . Most notebook computers are used lithium batteries, which are common lithium-ion battery. In addition there is a lithium polymer battery, but only in some high-end use of ultra-thin notebooks. Lithium batteries are generally set by the protection circuit and the capacity to monitor and communications circuits such as a few parts. From the parameter, the battery capacity is an indicator of concern. Current battery capacity is generally between 3000 ~ 4500mAh ,also there are some with 6000mAh capacity.
