18650 Lithium-ion Battery Types

18650 Lithium-ion batteries are a type of lithium-ion battery that are commonly used in a variety of electronic devices. There are several types of 18650 Lithium-ion batteries, each with its own unique features and specifications. Here are some of the most common types of 18650 Lithium-ion batteries:

Standard 18650 Lithium-ion battery: These are the most common type of 18650 li-ion batteries and are widely used in consumer electronics. They typically have a capacity of 2000mAh to 3500mAh, and a discharge rate of up to 10A.

High-capacity 18650 Lithium-ion battery: These batteries have a higher capacity than standard 18650 lithium-ion batteries, typically ranging from 3500mAh to 5000mAh. They are ideal for high-drain applications and can be used in devices such as flashlights, power banks, and e-cigarettes.

High-drain 18650 Lithium-ion battery: These batteries have a higher discharge rate than standard 18650 li-ion batteries, typically ranging from 15A to 30A. They are designed for high-drain applications such as vaping, RC cars, and power tools.

Protected 18650 Lithium-ion battery: These batteries have a built-in protection circuit that prevents overcharging, over-discharging, and short-circuiting. They are ideal for devices that require a high level of safety, such as flashlights and e-cigarettes.

Button-top 18650 Lithium-ion battery: These batteries have a protruding button on the positive end, which makes them compatible with devices that require a button-top battery, such as some flashlights and e-cigarettes.

Flat-top 18650 Lithium-ion battery: These batteries have a flat positive end, which makes them compatible with devices that require a flat-top battery, such as some power tools and vaping mods.
