More than 300 years ago, Benjamin Franklin began to capture lightning, which opened people's understanding of lightning and electricity. Since then, many people have been thinking about how to store the captured electricity, so Gradually, such things as batteries were produced. Indeed, as a very important invention in history, the emergence of batteries has indeed solved many problems and greatly improved various life efficiency.


The emergence of lithium batteries has made people more The understanding of electricity is getting deeper and deeper. The 18650 lithium battery is the lithium battery that has been used for the longest time and still exists. The shadow of the 18650 lithium battery can be seen in many places, including our OLIGHT torch, because Compared with other batteries, this kind of battery has obvious advantages, and the safety is relatively good. You can also check out the Olight UK Store for some great stuff. But for now, let me share with you each of the best 18650 batteries that provide solid performance and lasting light.

The 18650 battery is a cylindrical battery with a diameter of 18mm and a height of 65mm. The original purpose of the 18650 battery design is to supply power to the notebook computer. The battery of the notebook computer is basically this type of battery. Its energy density is the largest among the rechargeable batteries used on a large scale, and the discharge current can also withstand normal flashlights. , The stability at work is very good, and it is widely used in various electronic fields. It can be said that it is the most suitable battery for powering flashlights. Generally, high-end outdoor flashlights with high brightness are required, such as olight brand X7, R20, M series, SR series, etc., most of them use this kind of battery.


In practical applications, the combined volume of two 16340 (CR123A) is not much different from that of one 18650 battery, so many flashlight battery compartments are designed to accommodate one 18650 battery so that one 18650 battery can be used. Power supply, and can take into account two 16340 or CR123A battery power supply, great flexibility.

Some chargers are implemented using cheap solutions, which are not good enough in control accuracy, which may easily cause abnormal battery charging or even damage the battery. When buying a charger, try to choose a 18650 lithium-ion battery charger from a big brand. The quality and after-sale service are guaranteed to prolong the service life of the battery.

The brand-guaranteed 18650 lithium-ion battery charger has four protections: short circuit protection, overcurrent protection, overvoltage protection, battery reverse polarity protection, etc.
