About products and suppliers

An 18650 battery is a rechargeable lithium-ion battery that is widely used in various electronic devices. The "18650" refers to its size, with a diameter of 18mm and a length of 65mm. These batteries are known for their high energy density and long cycle life, making them popular in applications such as laptops, power tools, electric vehicles, and portable electronics. Li-ion 18650 batteries provide a reliable and consistent source of power, offering a balance between capacity, discharge rate, and overall performance. With their durability and ability to deliver high current outputs, 18650 batteries are suitable for demanding devices that require a stable power supply. Additionally, they are rechargeable. The rechargeable 18650 battery is a cost-effective and environmentally friendly choice compared to the disposable battery.

Types of 18650 batteries

There are different types of 18650 batteries available, each with its characteristics and intended applications. The ICR 18650 battery offers high energy density, making it suitable for devices that require a compact size and longer runtime. It is commonly used in devices such as laptops, digital cameras, and portable power banks. The ICR (Lithium Cobalt Oxide) chemistry provides a good balance between energy density and cost, making it a popular choice for everyday electronics.

The CR 18650 battery is indeed known for its high discharge rate, which makes it suitable for devices that require bursts of high power. The CR (Lithium Manganese Dioxide) 18650 battery is often used in applications such as flashlights, power tools, and other devices that need to deliver a significant amount of energy quickly. The INR 18650 battery offers a combination of high capacity and high discharge rate. It is suitable for devices that require both long runtime and high power output, such as electric vehicles and high-performance laptops. The INR (Lithium Nickel Manganese Cobalt Oxide) chemistry provides a good balance between energy density and power delivery.

How to charge an 18650 battery?

The 18650 battery capacity can vary depending on the specific model and manufacturer. Typically, the capacity of an 18650 battery ranges from around 1500mAh to 3500mAh or higher. It is generally advisable to charge the battery before it gets too low to ensure optimal performance and lifespan. To charge an 18650 battery, one will need a compatible 18650 battery charger. Follow these general steps: prepare the charger, insert the battery according to the polarity markings, connect the charger to a power source, monitor the charging process, and remove the battery once fully charged. It's important to use a charger specifically designed for 18650 batteries and follow any instructions or precautions provided by the charger's manufacturer. Avoid overcharging the battery to prevent potential damage. Handle and charge 18650 batteries with caution, avoiding extreme temperatures, water exposure, and physical damage.
