Common Sense Of Daily Use Of Lithium Batteries

1. Does the battery need to be activated?

The answer is yes, but this is not what users want to do. Before leaving the factory, the lithium-ion battery undergoes the following process: the lithium-ion battery case is filled with electrolyte --- sealing ---- formation, which is constant voltage charging, and then discharging, so a few cycles, so that the electrode fully infiltrate the electrolyte, fully Activation, until the capacity reaches the requirements, this is the activation process.

Partitioning is to test the capacity of the battery to select batteries of different performance (capacity) to classify, classify the battery grade, and perform capacity matching. The lithium-ion battery thus produced is already activated in the user's hands. The activation process of some of the batteries requires the battery to be in an open state, and then sealed after activation. This process can only be completed by a battery manufacturer.

All in all, battery activation is not something that users need to consider.

2. Should I charge for 12 hours for the first three times?

The answer is no need to charge for 12 hours.

The early nickel-metal hydride batteries of mobile phones require replenishment and trickle charging process. It may take about 5 hours to reach the fullest full state, but it does not need 12 hours. The constant-current and constant-voltage charging characteristics of the lithium-ion battery determine that its deep charging time does not require 12 hours.　

3. Is the rechargeable battery in the best condition?

There is a saying that when the rechargeable battery is used properly, it will appear in the best state in a certain cycle range, that is, the maximum capacity. This depends on the situation. Sealed nickel-metal hydride batteries and nickel-cadmium batteries, if used properly (such as regular maintenance to prevent the generation and accumulation of memory effects), generally reach their maximum capacity at 100 to 200 cycles, such as After 120 cycles of a nickel-metal hydride battery with a factory capacity of 1000mAh, its capacity may reach 1100mAh.

For lithium-ion batteries, there is no such hump phenomenon of circulating capacity. From the factory of the lithium-ion battery to the final battery scrap, the performance of its capacity is to use one less time. In the cycle performance test of lithium-ion batteries, I have never seen any signs of capacity recovery.

Therefore, lithium-ion batteries do not have the best condition.

It is worth mentioning that lithium-ion batteries are more susceptible to different performances due to changes in ambient temperature. Their performance will be best at an ambient temperature of 25 to 40 degrees, and their performance will be greatly reduced at low or high temperatures. . To make your lithium-ion battery fully display its capacity, you must pay careful attention to the use environment to prevent high and low temperatures.

Myth: Many people like to use battery power to automatically shut down and recharge. This is completely unnecessary.

Another measure of cycle life is time. Some experts have suggested that the life of general civilian lithium-ion batteries is 2-3 years, combined with the actual situation, such as the end of life with 60% capacity, plus the aging effect of lithium-ion batteries, using time to express the cycle life I think More reasonable.

Therefore, for lithium-ion batteries, there is no need to recharge them without electricity. Lithium-ion batteries are originally suitable for use at any time. This is also one of his biggest advantages for nickel-metal hydride batteries. Please take advantage of this feature. .
