Different models (in particular, different sizes) of the laptop battery, the higher capacity, the  longer working time. aside of volume and weight  factors , of course, the higher capacity the better.
But the same cell type, nominal capacity (for example, 600mAh) are the same, the actual measurement of the initial capacity different: for example one for 660mAh, the other is 605mAh, is the 660mAh one is better than 605mAh one?

Actual capacity may be high because the electrode materials to increase the initial capacity of more things, and less stable with the electrode things, the result is reused dozens of times after the rapid capacity of high capacity battery failure, the capacity Low battery is still strong. Many domestic batteries manufacturers often use this method to obtain high-capacity battery. The standby time users after six months it is worse than nothing. Civil those AA Ni-MH battery (that is, on the 5th battery), the general is 1400mAh, it also has standard high capacity (1600mAh), reason is the same.

★ improve the capacity cost is the expense of cycle life, battery materials, manufacturers are not modified up and down the article, is not really “improve” the battery capacity.
