We know that lithium batteries are the energy source of mobile products and the power of mobile products.

Many users use lithium-ion rechargeable batteries. When the stored power is used up, they need to be recharged to replenish the power. Don't underestimate the charging process. A good charger and correct charging method can maintain the battery's long standby time and extend the battery's service life. Regarding how to charge and maintain the method correctly, Regarding the correct charging and maintenance methods, after a period of actual use and reference, Xiamen ACEY NEW ENGERGY Technology co., Ltd summed up the following points:

1.Before the lithium battery leaves the factory, the manufacturer performs activation and pre-charge. Therefore, the battery has a residual battery. The newly purchased mobile phone battery is a lithium-ion battery. Then the first 3 to 5 charges are called the adjustment period, and it should be charged for more than 14 hours. Fully activate the activity of lithium ions. Lithium-ion batteries have no memory effect, but are very inert. They should be fully activated to ensure the best performance in future use.

2.Many users leave their mobile products on when charging. During the charging process, the battery discharges outwards due to the use of mobile products, and powers inward due to the charging of the battery, which is likely to cause voltage disturbances. Cause the circuit board of the mobile product to heat up, causing damage to the internal parts of the mobile product

3.Before charging, the lithium battery does not need to be discharged, nor can it be discharged. The current lithium battery chargers do not have the discharge function. If the charging speed can be adjusted, it is recommended that you charge as slowly as possible when charging, and reduce the fast charge. Method; neither slow charging nor fast charging should take more than 24 hours. Otherwise, the battery is likely to burn out the cells due to the huge electron current generated by the long-term power supply.

4.Some automated smart fast chargers actually only indicate that they are 90% full when the indicator lights change. At this time, the battery is protected from overcharging, and the charger will automatically change to slow charging to fully charge the battery. Don't cut off the power of the charger immediately, but also give the battery a period of time to recharge the battery. Fully charge the battery before using it, otherwise it will shorten the use time.

5.ACEY NEW ENERGY provides battery pack tester with charging and discharging. We have different voltage and current to select，70V 10A charging and 20A discharging aging tester，100V 20A charging 40A discharging aging machine etc.
