锂电池正确的充电方法

一、新电池充电

新电池一般要激活，电池放置一段时间后，会进入休眠状态，此时容量低于正常值，使用时间亦随之缩短，因此需要激

活。锂电池激活方法非常简单，只要经过3-5次正常的充放电循环就可激活电池，恢复正常容量。

二、旧电池充电

1、充电方法

旧电池是指已经充放电多次的电池，而不是报废的电池。锂电池的寿命与充放电的次数无关，它没有记忆效应，不论你怎

么充电，都不会影响充电循环次数。因此不要把电池用到完全没电才去充电，最好是当你能充电时，就尽量把电池充饱，充电

时间以2-3小时以内为宜，当然你也不一定非要充满。

2、充电电压

锂电池安全工作电压范围是2.8到4.2V，低于或高于这个电压范围，电池中的锂离子变得非常不稳定，甚至造成事故。为

保证电池处于安全范围，因此需要专门的充电器。这些充电器会自动根据电池当前状态而调整充电方式。

3、充电工具

锂电池充电要用专用的充电器，它可以保障充电的安全性。充电器工作时，以恒定的电流给电池充电，随着电池电压的升

高，充电器同时提高充电电压，以加快充电速度。当电池到达4.2V截止电压时候，此时电池大约仅冲入70%左右的电量(并

未饱满)。此时充电器即以恒定的电压，逐渐变小的电流对电池继续充电，当值至小于0.1A充电仍然检测到电池电压继续升

高时候才停止充电。

4、定期充电

长期不用的锂电池，应该以半电状态，存放在阴凉偏干燥的地方。满电存放有危险，目电池会有损害，而无电存放，电池

可能会被破坏，从而失去作用。在存放过程中，每隔3--6个月，要完成一个充电周期，做一次电量校准。

锂电池寿命一般有多长

锂电池一般能够完全充放300-500个充电周期，超过这个次数，电池就不能用了，当然，这只能作为参考。锂电池寿命和

充电次数无关，与充放电的周期有关，也就是从零电量充到满电量的次数。一个充电周期意味着电池的所有电量由满用到空。再由空充到满的过程，这并不等同于充一次电。比如说，一块锂电在第一天只用了一半的电量，然后又为它充满电。如果第二

天还如此，即用一半就充，总共两次充电下来，这只能算作一个充电周期，而不是两个。

在日常生活中，通常可能要经过好几次充电才完成一个周期。每完成一个充电周期，电池容量就会减少一点。不过，这个

电量减少幅度非常小，高品质的电池充过多次周期后，仍然会保留原始容量的80%，很多锂电供电产品在经过两三年后仍然照

常使用。当然，锂电寿命到了最终后仍是需要更换的

Correct charging method of lithium battery

1、 New battery charging

The new battery will generally be activated. After the battery is placed for a period of time, it will enter into a dormant state. At this time, the capacity is lower than the normal value, and the service time will also be shortened. Therefore, it is necessary to activate the battery

Live. The activation method of lithium battery is very simple. After 3-5 normal charging and discharging cycles, the battery can be activated to recover its normal capacity.

2、 Charging of old batteries

1. Charging method

Old batteries refer to batteries that have been charged and discharged for many times, not discarded batteries. The life of lithium battery has nothing to do with the times of charging and discharging. It has no memory effect, no matter what you do

It will not affect the number of charging cycles. Therefore, do not charge the battery until it is completely dead. It is better to fully charge the battery when you can

Time should be within 2-3 hours. Of course, you don't have to be full.

2. Charging voltage

The safe working voltage range of lithium battery is 2.8 to 4.2 V. Below or above this voltage range, the lithium ion in the battery becomes very unstable, even causing accidents. by

To ensure that the battery is in a safe range, a special charger is required. These chargers will automatically adjust the charging mode according to the current state of the battery.

3. Charging tool

Lithium battery charging requires a special charger, which can ensure the safety of charging. When the charger is working, it charges the battery with a constant current

High, the charger also increases the charging voltage to speed up charging. When the battery reaches the 4.2V cut-off voltage, the battery will only charge about 70% (and

Not full). At this time, the charger will continue to charge the battery with a constant voltage and gradually decreasing current. When the value is less than 0.1A, the battery voltage is still detected to continue to rise when charging

Stop charging only when the battery is high.

4. Periodic charging

Lithium batteries that are not used for a long time should be stored in a cool and dry place in a semi electric state. It is dangerous to store the battery with full charge, and the battery will be damaged

It may be destroyed and lose its function. During storage, a charging cycle shall be completed every 3-6 months to calibrate the electric quantity.

How long is the life of lithium battery

Lithium batteries can generally be fully charged and discharged for 300-500 charging cycles. The battery cannot be used beyond this number of times. Of course, this can only be used as a reference. Lithium battery life and

The number of charges is independent of the charging and discharging cycle, that is, the number of charges from zero to full. A charging cycle means that all the battery power is from full to empty. The process of recharging from empty to full is not the same as recharging once. For example, a lithium battery uses only half of its power on the first day, and then fully charges it. If the second

It is still the case. That is to say, it will be charged with half of the charge, and it will be charged twice in total. This can only be regarded as one charging cycle, not two.

In daily life, it usually takes several times of charging to complete a cycle. After each charging cycle, the battery capacity will be reduced a little. But this

The power reduction is very small. After several cycles of charging, high-quality batteries will still retain 80% of their original capacity. Many lithium battery power supply products will remain unchanged after two or three years

Frequently used. Of course, lithium batteries still need to be replaced after the end of their life
