Is the higher the capacity of the lithium battery the better?

Is the higher the capacity of the lithium battery the better? We all know that different type, especially different size of batteries, the higher the capacity, the longer the use of the battery. Regardless of volume, weight, and other factors, large capacity spare lithium battery is of course the higher the capacity the better.

The same large capacity spare lithium battery model, the nominal capacity (for example, 600mAh) is exactly the same, but the actual test initial capacity is different, for example, one is 660mAh, the other is 605mAh, so the 660mAh will be better than the 605mAh?

Actual situation is likely to be higher capacity battery, because the more increase in electrode material initial capacity, thereby reducing the electrode stability, the result is that after the circulation use of dozens of times, higher capacity batteries quickly become capacity failure, and the lower battery capacity is still strong.

Many domestic battery manufacturers tend to use this method to obtain higher capacity of the battery, but after using for six months the standby time is very poor. The AA nickel metal hydride batteries used (i.e., battery no. 5) are generally 1400mAh, but still have a standard ultra high capacity (1600mAh).

In fact, the principle is the same, the cost of increasing capacity is to sacrifice cycle life.
