How to purchase a second laptop battery ?

Notebook battery is the "power source", especially for those who often walk a friend, in addition select models with the ultra-long standby selling point, the timely preparation of a second battery is an urgent task. Meanwhile, the laptop battery is also a consumable, general use IBM Laptop Battery batteryin 2012 will be significantly decreased after the performance, coupled with some users usually do not pay attention to battery maintenance work, the battery performance,IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery, as well as the rapid decay of the examples of early retirement are not uncommon. Ran Unfortunately, the growing demand today, the battery market has not subsequently be further standardized. Not only the renovation, the phenomenon of counterfeiting occur from time to time, that is, original manufacturers, even in the same series There is also a man-made obstacles set up. And electoral laptop compared to the choice of the battery does not to mention easy!

A look at parameters

As the laptop battery is not universal, consumers must be masters of our own before buying the machine can accept the battery type, and in order to avoid being cheated, in the "look", the right not to relax the inspection of workmanship!

Currently, in addition to individual low-end notebooks use nickel-metal hydride batteries, most are used in ordinary lithium-ion batteries, lithium polymer batteries only in part the use of high-grade ultra-thin notebook. Lithium batteries are generally batteries Unit to protect the circuit and capacity for monitoring and communications circuit of several components. From the perspective of the parameters, the battery capacity is an indicator of concern. Now generally 3000 ~ 4500mAh, there are very few with a 6000mAh capacity. In theory the higher values in the same configuration using the longer.

The manufacturer of the laptop battery has a more detailed description, we often can see the "six-core 4400mAh", IBM FRU 92P1167 Battery,"4-pin 2200mAh" nominal value such as batteries, over time, we believe that directly determines the capacity of 4400mAh or 2200mAh laptop working hours. In fact, we talk about computer power consumption, the total nominal power use, rather than simply current. The battery power should be multiplied by current, voltage to the common 2200mAh, 3.6V batteries, for example, could have used some small way the composition of four batteries in series, their voltage is 14.4V, Capacity 2200mAh. Many 14-inch notebook, you might use 2 and 4 strings of 8-cell hybrid mode, the voltage remains at 14.4V, capacity doubled to reach 4400mAh, to ensure a longer usage time. However, the same is a 2200mAh, 3.6V batteries, if we adopt the 2 and 3 sony VGP-BPS2 battery strings of 6 cores hybrid approach,IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery, its battery capacity it will still be 4400mAh, voltage down to 10.8V, if we just look at capacity, its use of time should be, and 8 the same cell battery. If you press power, then it 8-cell lithium battery, the power should be 63.36Wh, 6 cores for 47.52Wh, 4 cores for 31.68Wh. If according to this value, the advantages of 8-cell lithium battery can be reflected.

Appearance, the general assembly of the battery shell mold is not original battery specifications, so loaded notebook computer will appear to take difficult or loose loaded situations; assembly of the battery is not original battery plate production print quality is good, writing and more rough is not clear, in any encounter when buying this kind of "original battery" would not buy. In addition, the renovation of the distinction between products and new battery is still in its electrode wear traces of heavier and therefore does not gloss and new batteries, buy encountered in the so-called "new batteries" do not buy.

Comment: Taken together, apart "6-pin 4400mAh" this parameter, the battery voltage is also a need to know the parameters.IBM ThinkPad Z60t Battery From the application point of view, low-voltage large-capacity battery (more parallel, less in series) to ensure the laptop longer standby time, while the battery is almost no additional cost!

Second, weigh the quality of

Very often, the quality of both the power and weight proportional, laptop batteries are no exception. As the original battery protection circuit are doing more monitoring in place, the quality is better on batteries, so the weight of the assembly of the battery than the jerry-building is much greater when you buy them by hand Dian Dian, if compared with the original laptop battery light a lot of words Such batteries need to be careful!

As the recent past, Dell, Apple, Sony, Lenovo and other laptop caught fire after another, making the image of the original battery much frustration, but overall the quality of original equipment batteries, or more outstanding. So I believe that choice should be based on a second battery or original products. Of course, the market compatible with many types of cells, some with the original brand notebook chip and the IC design and manufacture of high-quality batteries, not only have all the original battery protection, and stable performance, IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery,use of time is relatively long, the actual performance with the original battery is not much difference; but some small workshop production of The quality of the compatibility of the battery is not flattered, and the battery's sony VGP-BPS2A battery internal circuit design is extremely simple and the quality of batteries used in more times, and some have even adopted disassemble or brand-name batteries, this battery is compatible with the quality of the natural is not guaranteed; In addition, some laptop batteries inside the original battery failure,IBM ThinkPad Z61t Battery a number of business through self-change batteries way for original equipment batteries to obtain a "new life." However, this time piece of the battery is not the true sense of the original battery, but rather are compatible with the battery, its quality depends largely on how the quality of batteries. So, is compatible with the battery whether it is worth buying, in addition to the price, the key is to see how its quality. For those who are from small workshops compatible battery, even if the prices are a great advantage, not worth buying.
