subject: the battery life unnecessarily cut short [print this page] Recommendation 1: Each charge before the battery discharge is not necessary, but also harmful, because the battery life unnecessarily cut short.
Recommendation 2: Use a resistor to discharge the battery positive and negative is not desirable, the current can not control, easy for me into the 0V, and even lead to the battery series battery polarity reversal.
Answer is that the battery needs to be activated, but this is not the user to do. I visited the lithium-ion battery manufacturing plant, lithium-ion batteries at the factory prior to go through the following process: lithium-ion battery electrolyte impart SHELL - Seal - into, that is, constant voltage, then discharge, so for several cycles, so that fully soak the electrode electrolyte, fully activated in order to meet the required capacity far, this is the activation process - sub-content, is to test the capacity of the battery select a different performance (capacity) batteries are classified by the level of the battery, the capacity of matching . so out of the lithium-ion battery to the user is already activated off the hands of the.
We used nickel cadmium batteries and nickel-metal hydride battery is activated only after this into the factory. Some of these cells in the activation process requires opening the battery status, activate later sealing, this process may only batteries manufacturer to complete.
One problem here is that the factory battery factory hands of the battery to the user, this will be a very long time, sometimes as short as one month to six months, this time, because the battery electrode materials will be passive, so the manufacturer recommends the initial use battery is best for 3 - 5 times full charge-discharge process, in order to eliminate electrode materials passivation, to reach maximum capacity.
