1. Keeping lithium-ion batteries properly charged and discharged can extend battery life. Keeping the lithium-ion battery power between 10% and 90% is beneficial to protect the battery. When charging the batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.
2. If digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars, it is better to turn off these products because if the operating temperature exceeds 60 degrees Celsius, the lithium-ion battery will accelerate aging. Lithium battery charging temperature range: 0 ~ 45 degrees Celsius, lithium battery discharge temperature range 0 ~ 60 degrees Celsius.
3. If the cell phone battery needs to be charged every day, the reason may be that the battery is defectiveWhether it's time to "retire" for laptop owners, if the battery is plugged in for a long time, the battery will eventually deteriorate. It is better to remove the battery (high heat generated by the computer during use is not good for the laptop battery).
4. Under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.
How to properly charge lithium batteries Correct method of charging lithium batteries
1. High temperature charging is prohibited: high temperature will damage the internal parts of the battery and cause it to malfunction. discarded.
2. Excessive current is prohibited: if the current is too large and the temperature of the lithium battery is too high, the battery life will be shortened or even eliminatede.
3. It is prohibited to store the fully charged battery for a long time: Storing the fully charged battery for a long time will cause the capacity of the lithium battery to decrease.
4. It is prohibited to overcharge: this will cause the lithium battery to swell and be discarded.
5 It is prohibited to charge in an environment exposed to sunlight or rain: exposure to sunlight will cause the lithium battery to explode and burn.
6. It is prohibited to charge when the socket temperature is too high: if the socket temperature is too high, charging must be stopped.
7. It is prohibited to fail to charge in time when the battery indicates that the battery is too low: this will affect the battery life.
8. It is prohibited to charge with lead or other chargers: this would pose a risk to the safety of the circuit.
9.It is prohibited to recharge the electric vehicle immediately after driving: charging immediately after driving will continue to increase the battery temperature.
10. It is forbidden to put lithium batteries and metal objects together: Putting lithium batteries and metal objects together can easily cause a short circuit.
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, the capacity is lower than normal and usage. time is 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 beencharged and discharged several times, not to 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 charging cycles. 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 of 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 status ofbattery.
4. Charging Tools: Lithium batteries require a special charger, which can ensure charging safety. When the charger works, it charges the battery with a constant current. As the battery voltage increases, the charger also increases the charging voltage to speed up charging. When the battery reaches the cut-off voltage of 4.2 V, the battery is only charged to approximately 70% of its power (not full). 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 in a cool and dry place half charged. Storing the battery with a full charge will cause damage, whileStoring 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.
