Best 5 16650 battery manufacturers 2022

Lithium-ion battery technology is growing so rapidly that sometimes it becomes hard to keep track of all the different sizes available. As you read through the list, you will be amazed to find out that there are so many different types of lithium-ion batteries. The types of batteries differ greatly in shape, size, and purpose of use. They are divided into different categories depending on the purpose of their usage.

We are going to examine the differences between 18650 and 16650 batteries here. So, let’s begin.

16650 vs. 18650 Batteries: What’s The Difference?

Some electric cars and some laptop batteries use 18650 cells, which provide capacities of 1500 to 3500 mAh.

A 16650 battery is an ideal replacement for a CR123A battery. It is a type of lithium-ion cell that is only a few millimeters shorter than an 18650 cell, so it fits into a CR123A flashlight. For consumers to understand the differences between these types, the basic characteristics are enough.


There are two types of 18650 batteries, a protected one and an unprotected one. In the case of protected ones, the electronic circuit is embedded in the cell packaging. Protected batteries are mostly recommended for use as they protect the cell from overcharging, heating, and discharging.

A rechargeable battery, like any other, has a maximum amount of times it can be recharged. The good thing about 18650 batteries is that they can be recharged 300 to 2000 times, which is more than enough. The packaging of a battery includes specific information about:

· Protected mode to prevent overcharging and overdrawing.

· Maximum or optimal battery voltage.

· The capacity of the battery in mAh.

· Low self-discharge rate, so it can hold a charge for as long as possible.

They can be used for flashlights, electronic devices, laptops, vaping, and even some electric vehicles.


First of all, you should know that this type of battery is typically used only in flashlights. This battery is typically used as a replacement for CR123A batteries. As a consequence, 16650 batteries are not just bigger, they also have a slightly higher voltage, so you should keep this in mind. As a result, your flashlight’s performance could be affected. Its power is the same as two CR123A batteries, i.e. 3.7 V, which is the same as an 18650 battery. These batteries have the advantage of being able to be used for a longer period of time than their counterparts CR123A batteries.

One single cell generally weighs around 40 grams and offers a nominal capacity of 2400mAh which is very low than that of 18650.

The two battery types have nothing in common aside from their length and shape.
