How to charge lithium battery correctly?

1)The first point is don't overcharge. Then, how long does it take?

Lithium batteries are all activated when they leave the factory, So some businesses still hold the outdated view of "activation", Which is wrong. And we used to say that the first three times charging of a new battery is continuously charged for 12 hours, which is already the old common sense of the Ni MH battery era.

We know that the lithium batteries have protection circuit, And the battery will not break down immediately after long-time charging. But after the battery protection circuit works, he battery will enter to a charging and discharging cycle. This is the invisible consumption of the battery charging cycle, thus reducing the service life of the battery.

Generally, the lithium battery will be fully charged in 2-3 hours. After charging to 90% of the power, the battery is basically in a slow charging process. At most, another 1-2 hours charging is enough. That is, charge for 4-5 hours totally, no more than 6 hours.

2)The second is do not over discharge.

Some people usually run out of batteries and they don't charge until the device turns off automatically. This can easily cause over discharge of the battery.

Over discharge has a serious adverse effect on the battery life. Maybe 1-2 times of complete discharging will make the battery useless. Therefore, the battery can be charged at 10% power, at least 3% power must be charged.

Another situation is that the battery is not used for a long time, but there is not much power before it is stored, resulting in the battery "chronic suicide".

At present, some equipment will remind when the power is still 5-10%, and then automatically shut down when the second reminder. It is estimated that the second reminder will be 2-3% power, there is little electricity left. Therefore, it is strongly recommended that after the automatic shutdown of the equipment, do not try to turn on the machine again. Charging as soon as possible is the most important thing. It's best to charge before the first reminder.

3)The third is what is the charge cycle or we can say cycle life.

Many people think that the life of lithium battery is the number of charging times, Which is actually wrong. Strictly speaking, it should be called charging cycle. A complete charging cycle is to charge 100% and then discharge 100%.

The life of a lithium battery is about 300-500 complete charging cycles. So the correct statement about lithium battery life should be 300-500 times of complete charge and discharge.

That is to say, if a 100% full power battery discharge 50% power and then charge 30% power, This is not a complete cycle. A complete cycle is to charge and discharge with 100% power.

Lithium battery has no memory effect. So we can use and charge the battery at any time to reduce the cycle life.

4)The fourth point is use environment of lithium battery

Using a lithium battery in a hot or cold environment also has a bad impact on the battery life.

The results show that the temperature range of lithium battery charging is 0 ~ + 45 ℃, The temperature range of discharging is - 20 ~ + 60 ℃, And the best environment temperature for long-term storage is - 20 ~ + 35 ℃.

4)The third is what is the charge cycle or we can say cycle life.

Many people think that the life of lithium battery is the number of charging times, Which is actually wrong. Strictly speaking, it should be called charging cycle. A complete charging cycle is to charge 100% and then discharge 100%.

The life of a lithium battery is about 300-500 complete charging cycles. So the correct statement about lithium battery life should be 300-500 times of complete charge and discharge.

That is to say, if a 100% full power battery discharge 50% power and then charge 30% power, This is not a complete cycle. A complete cycle is to charge and discharge with 100% power.

Lithium battery has no memory effect. So we can use and charge the battery at any time to reduce the cycle life.

5)The fourth point is use environment of lithium battery

Using a lithium battery in a hot or cold environment also has a bad impact on the battery life.

The results show that the temperature range of lithium battery charging is 0 ~ + 45 ℃, The temperature range of discharging is - 20 ~ + 60 ℃, And the best environment temperature for long-term storage is - 20 ~ + 35 ℃.

6)The fifth point is how to deal with lithium battery when they are not in use.

The self discharge rate of lithium battery is a little bit high. Therefore, for the sake of safety, If the lithium battery does not need to be used, it is best to fully charge it first, and then store it in a plastic bag.

These batteries should be charged and discharged every 1-2 months to maintain the activity of lithium ion. The longest time should not exceed 3 months.Because if the lithium battery is not used for a long time, the lithium ion activity will decline. This has an adverse effect on battery life.
