Wrong information: 2 Nominal capacity of the same (for example, 800mAh) batteries, if an actual measured capacity of 860mAh, the other is 805mAh, so 860mAH’s definitely better than the 805mAh.(Click here to buy Lenovo ThinkPad i1391 battery.)

Truth: In general, different models (different sizes) and lithium-ion battery, the higher the capacity the longer the time used. If you set aside such factors as size and weight, of course, is the capacity the better. But for two nominal capacity of the same (for example, the example above) the battery may not be.

Since the actual high capacity battery that is likely to add in the electrode materials used to increase the initial capacity of the material, reducing the stability of electrode materials used. (Click here to buy Lenovo ThinkPad W700 battery .)

The result is shown in dozens of cycles, after the rapid decay of high capacity piece, while the capacity is still low strong. Many domestic firms in order to reduce costs and expand sales, often on the use of such tools to produce high-capacity battery. Users will find that six months after the use of working time is much shorter. In short, to improve capacity at the expense of sacrificing cycle life, battery makers are not material up and down the article, it is impossible to truly improve the battery capacity.
