18650 power lithium battery is a common type of lithium battery widely used in fields such as electric tools, handheld devices, drones, etc. The correct activation method is crucial for improving battery performance and extending its lifespan after purchasing a new 18650 power lithium battery. This article will introduce the activation method of 18650 power lithium batteries to help readers better understand how to correctly activate this type of battery.

What is 18650 power lithium battery?

18650 power lithium battery is a common standard specification for lithium-ion batteries, with a diameter of 18mm and a length of 65mm, hence its name. It has high energy density, high voltage, and small volume, making it suitable for equipment and systems that require high-performance power sources.

Why is activation necessary?

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

How to activate 18650 power lithium battery?

1) Charging: First, insert the newly purchased 18650 power lithium battery into a professional lithium battery charger for charging. When charging for the first time, it is recommended to choose a lower charging current to avoid excessive impact on the battery. Generally, it is recommended to choose a charging current of 0.5C for initial charging, and then unplug the battery after it is fully charged.

2) Discharge: Connect a fully charged 18650 power lithium battery to a device or electronic load for a complete discharge process. By discharging, chemical reactions inside the battery can be activated to achieve optimal performance.

3) Cyclic charging and discharging: The cyclic process of charging and discharging is repeated, usually recommended to perform 3-5 cycles of charging and discharging to ensure that the chemical substances inside the battery are fully activated, improving the performance and cycle life of the battery.

When activating 18650 power lithium batteries, the following points should be noted:

1) Avoid overcharging and discharging: During the activation process, avoid overcharging or discharging the battery to prevent damage to its performance and safety.

2) Choose the appropriate charger: Use a professional 18650 battery charger for charging and avoid using improper charging equipment to prevent damage to the battery.

3) Charging current selection: When charging for the first time, choose an appropriate charging current. It is usually recommended to choose 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 changes of the battery to avoid damaging it due to overheating.

The correct activation method can help 18650 power lithium batteries fully utilize their performance and extend their service life. During the activation process, it is important to choose the appropriate charger, charging current, and avoid overcharging and discharging to ensure the safety and stable performance of the battery. I hope that through the introduction in this article, readers can master the correct activation method for 18650 power lithium batteries and better apply and manage this type of battery.
