Nitecore IMR 18350 Battery

The Nitecore IMR 18350 Battery is the best 18350 battery on the market because it has great quality and craftsmanship. We like the fact that the manufacturer has succeeded to produce the best energy source for their flashlight products. This battery perfectly fits the Nitecore flashlights, and it is also a wise choice for other high drain devices


If you have a high drain device like an electronic cigarette, you¬†definitely need an 18350 battery as its energy source. The ‚Äė18350‚Äô¬†stands for the size of the battery, which means 18mm in diameter and¬†35mm in length. Since it has similar size with regular CR123¬†batteries, people may mix them up. But, there are big differences¬†between these two kinds of batteries.

Firstly, the 18350 batteries are rechargeable, while the CR123 batteries are not. Although the 18350 batteries have smaller capacity and don’t last as long compared with the CR1223 batteries, they can be recharged for hundreds of times, translating to superior long term performance. So, using the 18350 batteries will help you save quite a sum of money.

Secondly, the 18350 batteries are slightly thicker than CR123 batteries. Generally, an 18350 battery won’t fit in the case for CR123 batteries, while a CR123 battery can be used in devices supported by 18350 batteries. But, it’s meaningless or even dangerous to try to use either one to take the place of the other. The CR123 batteries have much lower voltage than 18350 batteries, so they can’t produce as strong of an output. On the flip side, the 18350 batteries produce heavier current and may damage the appliances which can only be powered by CR123 batteries.

If you are in need of the best 18350 batteries, you may find it difficult to find quality product. As the 18350 batteries are not the main stream products, to compete with the CR123 batteries, the manufacturers often exaggerate when advertising their products. It’s quite common that people run into batteries which have half the capacity as advertised and have no durability at all.

To help you find the best 18350 battery, we have strictly tested popular products. The 5 products below are highly recommended, because they have better performance, security, durability and ease of use.
