18650 power lithium battery it is a common type of lithium battery, widely used in electric tools, handheld devices, unmanned aerial vehicles and other fields. After purchasing the new 18650 power lithium battery, the correct activation method is very important to improve the battery performance and prolong the service life. This article will introduce the activation method of 18650 power lithium battery to help readers better understand how to activate this type of battery correctly.

1. What is 18650 power lithium battery?

18650 power lithium battery is a common standard specification of lithium ion battery, whose diameter is 18mm and length is 65mm, so it is named. It has high energy density, high voltage and small volume, and is suitable for equipment and systems requiring high performance power sources.

2. Why do I need to activate?

In the production process of 18650 power lithium battery, the battery will be in a low energy state, and it needs to be activated to activate the chemical reaction of the battery, so as to achieve the best performance state. The correct activation method can help the battery achieve the maximum charge storage and release capacity, and improve the stability and cycle life of the battery.

3. How to activate 18650 power lithium battery?

(1) charging: first, insert the newly purchased 18650 power lithium battery into the professional lithium battery charger for charging. When charging for the first time, it is recommended to select a lower charging current for charging to avoid excessive impact on the battery. Generally, it is recommended to select a 0.5C charging current for the first charging, when the battery is fully charged, it can be pulled out.

(2) discharge: connect the fully charged 18650 power lithium battery to the equipment or electronic load for a complete discharge process. By discharging, the chemical reaction inside the battery can be activated, so that the battery can reach a better performance state.

(3) cyclic charging and discharging: repeat the cyclic process of charging and discharging. It is usually recommended to conduct 3-5 cyclic charging and discharging to ensure that the chemicals inside the battery are fully activated, improve battery performance and cycle life.

4. Precautions

when activating 18650 power lithium batteries, pay attention to the following points:

(1) avoid overcharging and discharging: during the activation process, avoid overcharging or overdischarging the battery, so as not to damage the performance and safety of the battery.

(2) select the appropriate charger: Use a professional 18650 battery charger to charge, avoid using improper charging equipment, so as to avoid damage to the battery.

(3) charging current selection: when charging for the first time, select an appropriate charging current for charging. Usually, it is recommended to select a charging current of 0.5C, and then gradually increase the charging current according to actual needs.

(4) prevent overheating: during the charging and discharging process, pay attention to the temperature change of the battery to avoid damaging the battery due to overheating.

The correct activation method can help 18650 power lithium batteries give full play to their performance and prolong their service life. During the activation process, attention should be paid to choosing the appropriate charger, charging current and avoiding excessive charging and discharging to ensure the safety and stable performance of the battery. It is hoped that through the introduction of this article, readers can master the correct activation method of 18650 power lithium batteries and better apply and manage this type of batteries.
