Low-temperature lithium batteries are durable goods, and there is no need to match them with expensive original seat chargers. Some individual seat chargers can be used. The price is 15-20 yuan, eliminating the need for direct charging to be attached to the mobile phone limit.The seat charger is divided into fast charging (about 2-3 hours) and slow charging (about 10 hours). If there are more batteries, fast charging is better.In addition, because of the characteristics of low-temperature lithium batteries, there is no need for discharge and overcharge operations.The life of the battery depends entirely on the amount of effective charging time.In other words, even if you only use half of it and start charging, it will have no effect on battery life.
1. Consciousness memory effect Battery memory effect refers to the reversible effect of the battery, that is, the function that can be restored after the battery takes effect.The memory effect refers to the battery taking the initiative to adhere to this specific bias after being confined to a specific work cycle for a long time.This was first defined in nickel-cadmium batteries. Nickel-cadmium bag batteries do not have a memory effect, and sintered batteries have a memory effect.Nickel-metal hydride (commonly known as nickel-metal hydride) batteries are not bound by this definition of memory effect.Recommendation 1: It is unnecessary and harmful to discharge the battery before each charge, because the service life of the battery is unnecessarily shortened.Recommendation 2: It is not advisable to use a resistor to connect the positive and negative of the battery to discharge. The current cannot be controlled, and it can easily be over-discharged to 0V, which even leads to the reversal of the battery properties of the series battery pack.
2. The battery needs to be activated. The low-temperature lithium battery has to go through the following process before leaving the factory: the low-temperature lithium battery shell is filled with electrolyte-sealed-formed, which is to charge at constant voltage, and then discharge. How many cycles are carried out so that the electricity fully infiltrates the electrolyte and is fully activated until the capacity reaches the request. This is the activation process-capacity separation, which is to test the capacity of the battery and select batteries with different functions (capacity) to classify, divide the battery level, and match the capacity.The low-temperature lithium battery that comes out in this way has already been activated in the hands of the user.The battery from the battery factory is in the hands of the user. This time is sometimes very long, as short as 1 month, and as long as half a year. At this time, because the battery's electrical data will be passivated, the manufacturer advocates the use of the battery for 3-5 full charging processes, in order to eliminate the passivation of the electrical data and reach the capacity.
3. The first three times, there is no need to charge for 12 hours. Early mobile phone Ni-MH batteries need to make up for the trickle charging process. It may take about 5 hours to reach the full state, but it does not take 12 hours.The constant current and constant voltage charging characteristics of low-temperature lithium batteries determine that its deep charging time does not need to be 12 hours.
4. Is there a condition of the rechargeable battery? The nickel-based battery is in a condition, and it can reach its capacity between 100-200 cycles.For liquid low-temperature lithium batteries, there is basically no such hump of reincarnation capacity.Low-temperature lithium batteries are not in condition.
5. The greater the charging current, the faster the charging. For the charging of low-temperature lithium batteries, within a certain current range (1.5C--0.5C), the constant current and current value of the constant current and constant voltage charging method cannot be improved, and the time to fully charge the low-temperature lithium battery cannot be shortened.
