The notebook computer batteries is relative to the heart, and the advantage of the desktop. Most laptop batteries and now works mostly in the time between 2 ~ 4 hours, may not meet the needs of users. Thus, for those who need to move office or often ambulating, prepare a backup battery is very necessary. Moreover, notebook batteries are used in a year later, consumables its performance will be decreased obviously, plus some customers usually don’t pay attention to and maintenance of the battery, the battery performance quickly and is not a rare example of early scrapping. How to choose a cost-effective battery is keen to know many users. We will talk about the battery.
Notebook batteries and not common battery, the user must first understand oneself before the battery types. Support machine, Most laptop computers using lithium battery, which is the lithium ion battery is common. Another is the lithium battery, but only in some high-end thin laptop. Lithium battery is commonly by core group, the protection circuit and the capacity of monitoring and communication circuit, etc. From the parameters, battery capacity is one of the most concern. Currently battery capacity in 3000 commonly 4500mAh ~ between, also have the capacity of 6000mAh equipped.

The higher the theory, at the same time the configuration used is longer. The manufacturer for laptop battery has a detailed introduction, we often can see the “six core 4400mAh”, “four core values 2200mAh”, but actually nominal battery capacity 4400mAh 2200mAh or not directly determine the working time of the notebook. When we talk about the computer power consumption, total want to use power nominal, rather than simply current. In common 2200mAh, 3.6 V core, for example, some little May 4th series components, the battery voltage, capacity 2200mAh 14.4 V. While many 14 inches above the notebook, may adopt 2 and 4 series of eight core mixed mode, voltage, capacity of 14.4 V 4400mAh achieve doubled, longer time. However, also is the core 2200mAh, 3.6 V, if the 2 and 3 of the mixed mode 6 core, its battery capacity remains for 4400mAh, voltage drops to 10.8 V, if at the time of its use capacity, and eight core battery should be. If the power to calculate, eight core lithium battery, power should be 63.36 Wh, 6 core for 47.52 Wh, four core for 31.68 Wh. If this value, the core of lithium battery 8 advantage to manifest.
When the choose and buy must pay attention to the battery appearance, generally brand battery shell mould is more normative, then when the notebook computer may be difficult or loose from the loading condition; Don’t buy when the choose and buy another coarser and label handwriting clear cell. In addition, some new batteries battery as high guard and revision of the battery, the battery should also pay attention to the electrode wear generally heavier and glossiness traces are not new battery.
