Method:
Avoid charging at excessively high temperatures
If charging is above the specified operating temperature, c i.e. above 35°C. lithium batteries are used in special environment, the battery power will continue to decrease, that is, the battery power time will not be as long as usual. If the device is charged at such temperatures, the damage to the battery will be greater. Even storing batteries in a hot environment will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a proper operating temperature is a good way to extend the life of lithium batteries.
Avoid charging at too low temperatures
If you use lithium batteries in low temperature environments, i.e.below 4°C you will also find that battery life is reduced. cell phones have original lithium batteries that cannot even be charged in low temperature environments. But don't worry too much, this is just a temporary situation, different from using in high temperature environments. Once the temperature rises and the battery molecules are heated, the battery immediately returns to its previous capacity.
Frequent use
If you want to maximize the performance of a lithium-ion battery, you need to use it frequently to keep the electrons in the lithium battery in a circulating state . If you do not use lithium batteries frequently, remember to cycle the lithium battery every month and perform power calibration, that is, deep discharge and a chadeep rheum.
Detailed information:
The lifespan of lithium batteries is generally 300 to 500 charge cycles. Assuming that the power provided by a full discharge is 1Q, if the power reduction after each charge cycle is not taken into account, the lithium battery can provide or supplement a total of 300Q to 500Q of power over of its lifespan. From this we know that if you charge 1/2 each time, you can charge it 600-1000 times; if you charge it 1/3 each time, you can charge it 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how you charge it, the total amount of electricity added is 300Q to 500Q, which is constant.
So we can also understand this: battery life in bedhium is related to the total charge capacity of the battery, and has nothing to do with the number of charge times. There is little difference in the impact of deep discharge, deep charge and shallow discharge on the life of lithium batteries. Well, some MP3 manufacturers claim in their propaganda: “A certain model of MP3 uses a powerful lithium battery that can be recharged more than 1,500 times. » This is only to deceive consumers and lead them to ignorance.
In fact, surface discharge and surface charge are more beneficial for lithium batteries. Only when the product power module is calibrated for lithium batteries is it necessary to deeply discharge and charge. Therefore, products powered by lithium batteries do not necessarily have to stick to the process. Everything is done with convenience in mind. You canYou can charge them at any time without worrying about affecting their lifespan.
How to charge lithium batteries correctly? Correct charging method for lithium batteries
The correct charging method for lithium batteries
In fact, surface charging and Surface charge are more beneficial for lithium batteries. Therefore, products powered by lithium batteries can be. charged at any time. Recharge without worrying about affecting the lifespan. Typically, lithium batteries can be charged for eight to twelve hours.
The longest duration should not exceed one day. In addition, if it is not used for a long time, the lithium battery needs to be charged for two hours. every two months, otherwise it will cause battery performance degradation.
Precautions for charging batterieslithium batteries
It should be noted that lithium batteries should avoid charging at too high temperatures if the temperature is above 35°C. When charging in the above environment, the battery power will continue to decrease, the battery power time will be shortened, and the battery damage will be very serious.
Also avoid charging at too low temperatures. The original lithium batteries of some mobile phones cannot be charged even in low temperature environments.
But this is only a temporary situation. Unlike use in high temperature environments, once the temperature is increased, the battery molecules will be heated and immediately return to normal.
If you do not use lithium batteries frequently, remember to perform a charge cycle for the battery au lithium every month, that is, deep discharge and deep charge once.
1. New batteries usually need to be activated. After the battery is left for a while, it will enter a dormant state. At this time, capacity is lower than normal. The value and usage time are also shortened, so it must be activated. The lithium battery activation method is very simple. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity.
2. How to Charge Old Batteries: Old batteries refer to batteries that have been charged and discharged multiple times, not discarded batteries. The lifespan of a lithium battery has nothing to do with the number of charges and discharges. It has no memory effect. No matter how you charge it, it will not affect the number of cycless load. Therefore, do not charge the battery until it is completely empty. It's best to fully charge the battery when you can. Charging time should be 2-3 hours. Of course, you don't have to charge it completely.
3. Charging Voltage: The safe operating voltage range for lithium batteries is 2.8 to 4.2 V. Below or above this voltage range, the lithium ions in the battery become unstable. To ensure the battery is within a safe range, a specialist charger is required. These chargers automatically adjust the charge based on the current battery condition.
4. Charging Tools: A special charger is required to charge lithium batteries, which can ensure charging safety. When the charger works, it charges the battery with a constant current. As the battery voltage increases, the chaThe regulator also increases the charging voltage to speed up charging. When the battery reaches the cut-off voltage of 4.2 V, only about 70% of the battery is charged. At this time, the charger continues to charge the battery with constant voltage and gradually decreasing current. When the value reaches less than 0.1A, it always detects that the battery voltage continues to increase.
5. Regular charging: Lithium batteries that have not been used for a long time should be stored half-charged in a cool, dry place. Storing the battery with a full charge will cause damage, while storing it without a charge can damage the battery and render it useless. During storage, a charge cycle should be performed and a power calibration performed every 3-6 months.
