A. How to charge a new lithium-ion battery charger

On the charging method of the new lithium-ion battery charger, there have always been arguments from all sides. The most widely circulated is that the first charge is to be filled with 18 hours so that the battery charger is in an active state. This statement is wrong. Tracing its roots, this statement is the earliest for nickel battery chargers. Still, we ignore the lithium-ion battery charger and nickel battery chargers have a very different The difference between a lithium-ion battery charger, and a nickel battery charger is very significant, so overcharging a lithium-ion battery charger will only bring immeasurable damage to the battery charger itself, not to mention the legendary effect of activating the battery!

Secondly, how to use the lithium-ion battery charger correctly.

On the use of lithium-ion battery chargers, many people still have a misconception that is deep and shallow the charger life has a huge impact. Scientific research shows that the life of the lithium-ion battery has nearly 500 cycles, so when we use the charger to charge more power, the charger itself is not too damaged. In other words, the charger and Other factors such as shallow discharge and shallow charge do not harm the charger.

Third, how to charge in normal use

About lithium-ion batteries in normal use should be how to change this issue? There are many different opinions. Some partners said to use the automatic shutdown, a little electricity is not left before charging, but some partners told with the use of the charge, on this issue, I have been using action in the practice of the first statement, but found that there is no need to do so, in the end, why is it? Let's take a look at it together~~

Reason one: the life of the lithium-ion battery is generally 300 ~ 500 charging cycles. Assuming that a complete discharge of the supply of electricity for 1Q, not taking into account the power will be reduced after each charging process, the lithium-ion battery can supply a total of 300Q ~ 500Q of electricity. If the battery is recharged 1/2 at a time, it can be recharged 600-1000 times; if it is recharged 1/3 at a time, it can be recharged 900-1500 times; if it is restored randomly, the number of times is variable. In short, a total of 300Q-500Q of power can be replenished into a constant. Therefore, the life of a lithium-ion battery is related to the total charge but has nothing to do with the number of times it is charged.

Reason 2: In fact, shallow discharge and shallow charging are more beneficial for Li-ion batteries. Deep discharge and deep charging are only necessary when the product's power module is calibrated for Li-ion batteries. Therefore, in the process of daily use, you can not be bound to use photoelectricity and then charge. You can use it with the charge to facilitate the first.

IV. Charging in high-temperature situations

We all understand that if the mobile phone lithium-ion battery is used for a long time, the temperature will continue to rise, and the lithium-ion battery used in mobile phones will discharge itself at high temperatures, which explains why the power is consumed faster when the mobile phone is at a higher temperature.
