What is an 18650 Battery?

The 18650 battery is a cylindrical-shaped, rechargeable lithium-ion battery that measures 18mm in diameter and 65mm in length. It was first introduced by Sony in the mid-1990s for use in laptops, but has since gained popularity as a power source for many consumer electronic devices.

One of the reasons why the 18650 battery is so popular is its high energy density. This means that it can store more energy than other types of batteries of similar size. As a result, it’s commonly used to power high-performance flashlights, e-cigarettes, and other portable electronics.

Another advantage of the 18650 battery is its long lifespan compared to other types of rechargeable batteries. With proper care and handling, an 18650 battery can last for hundreds or even thousands of charge cycles before needing to be replaced.

It’s important to note that not all 18650 batteries are created equal. There are many different brands and models available on the market today at varying price points and quality levels. When purchasing an 18650 battery, it’s important to do your research and choose a reputable brand with good reviews to ensure you’re getting a safe and reliable product.
