1. Recognize the memory effect

　　The battery memory effect refers to the performance of the battery's reversible failure, that is, the performance that can be restored after the battery fails. Memory effect refers to this specific tendency to automatically maintain this specific tendency after the battery is undergoing a specific working cycle for a long time. The earliest definition of nickel -cadmium batteries, nickel -cadmium -type batteries do not have a memory effect, sintering battery has a memory effect. And the current nickel metal hydrogen (commonly known as nickel -metal hydride) battery is not constrained by this memory effect.

　　Suggestion 1: It is unnecessary to discharge the battery before each charging, and it is harmful, because the life of the battery is unnecessary. Suggestion 2: It is not advisable to discharge the positive and negative poles of a resistor to the battery. The current cannot be controlled. It is easy to put it to 0V, which even causes the battery polar reversal of the series battery pack.

　　2. The battery needs to be activated

　　The lithium -ion battery must go through the following process before leaving the factory: the lithium -ion battery shell instill the electrolyte -seal -into a constant voltage charging, and then discharge. As the capacity meets the requirements, this is the activation process -tolerance, that is, to test the battery of different performance (capacity) of the battery to classify, divide the level of the battery, match the capacity matching, etc. It has been activated.

　　The battery from the battery factory is to the user's hands. This time is sometimes very long, as short as one month, and half a year long. At this time, because the battery electrode material will passivation, the manufacturer recommends that the battery used for the first time is best to perform 3 - Five full filling process in order to eliminate the passivation of the electrode material and reach the maximum capacity
