What are 18350 Batteries?

a human holding 18350 Battery

18350 batteries are powerful and efficient rechargeable cells that use advanced lithium-ion chemistry as their composition. These batteries are commonly used in high-drain devices like flashlights, cameras, and medical and security systems.

As rechargeable cells, these lithium 18350 batteries can go through hundreds of charging and discharging cycles throughout their lifespan. The number of cycles depends on storage/drain temperature, charging/discharging current, general battery quality, and the quality of the 18350 battery charger.

Note: To ensure maximum efficiency, 18350 batteries should always be recharged only using battery chargers intended for 18350 lithium batteries.

Features & Specifications of a Standard 18350 Battery

  • Dimensions (D x H)- 18 x 35 mm (0.708 x 1.378 inches)
  • Nominal voltage- 3.6 to 3.7 volts
  • Capacity- 600 to 1400 mAh
  • Standard discharge current- between 2 and 10+ Amps
  • Maximum burst current- 15 or more Amps

Types of 18350 Batteries

18350 batteries can be classified as follows based on the cell chemistry;

  • IMR 18350– Has a composition chemistry of LiMn2O4 (Lithium Manganese Oxide), a nominal voltage of 3.6-3.7 V per cell, and the maximum recommended charging voltage is 4.2 V. This type usually holds a smaller capacity but can deliver very strong currents.
  • INR 18350– Has a composition chemistry of LiNiMnCoO2 (Lithium Manganese Nickel Cobalt Oxide), very similar to the IMR version. Capable of providing strong currents with a slightly lower capacity.
  • IFR 18350– Has a composition chemistry of LiFePO4 (Lithium Iron Phosphate), a nominal voltage of ~3.2 V per cell and the maximum recommended charging voltage is 3.5-3.6 V. These types are the safest types. Still, they do require a built-in BMS (battery management system) to operate safely.
  • ICR 18350– Feature a LiCoO2 (Lithium Cobalt Oxide) composition chemistry, a nominal voltage of 3.6-3.7 V, and the maximum recommended charging voltage of 4.2 V. These types usually have a high capacity, but the maximum allowed current is limited.

A Buyer’s Guide to Choose the Best Flashlight

flashlights on the table

To choose the best flashlight, it is important to pay attention to some of the flashlight’s specifications to determine the level of its overall functionality. Below are some specs that will help you choose a flashlight based on your intended purpose.

Light Output & Beam Throw

The light output, which is measured in lumens, tells you how strong the flashlight beam can shine. Higher the lumen count, the brighter the light.

The lumen counts in flashlights typically vary from 1- 4000 lumens. Different lumen counts are suitable for different purposes. Although a higher lumen count means bright light, you don’t necessarily have to choose the highest lumen count. 

The beam throw is the distance traveled by the flashlight beam. Longer the beam range, the farther the illumination pathway. 

Pick a suitable maximum light output and beam throw distance based on the purpose you see yourself often using the flashlight for.

Multiple Lighting Modes

It’s always good to have a selection of lighting levels to toggle between the modes based on the lighting requirements. 

For example, if you are taking a night stroll or camping, you may need a very bright light. Still, at the same time, if you need the flashlight for some work within the house, a moderately bright light will get the job done.

But a flashlight that gives you this flexibility between different brightness levels means you can use it for various purposes. 

Battery Capacity & Run Times

Although this review is about 18350 flashlights, meaning the above-listed flashlights utilize the 18350 batteries, the run times vary based on the capacity and type of 18350 the flashlight is compatible with. 

Constant use on high output can drain the battery life pretty fast. It is worth considering if a flashlight can deliver an acceptable run time on the highest output. To preserve battery life as long as possible, some flashlights have ultra-low, eco or moonlight modes that give out a 0.5-1 lumen output. 

For example, a flashlight that is excellent at runtimes is the Nitecore MT10C which can run for 30 minutes on turbo mode and for 120 hours on ultra-low mode.

Portability

Whether you want to take your flashlight on your travels or use it around the house, the flashlight shouldn’t take up much storage space. To ensure easy and convenient portability, choose a flashlight that has a reasonable size and weight.

Besides, when we have options where super technology is built into small pieces of tech like the Nitecore MT10C, why even choose a bulkier model.

Durability

The durability of a flashlight matters for you to be able to rely on it. Even if it is reasonably priced, no one would want a flashlight that can easily break when mistakenly dropped. 

Check the factors that contribute to the durability of a flashlight, like the build quality, waterproofing ability and impact resistance. 

Build quality is important no matter what you intend to use it for. The build quality gives the flashlight its shock-absorbing properties allowing a bit of rough use. This comes in handy if you intend to use your flashlight outdoors very often.

Similarly, you can go for a higher waterproof-rated flashlight if you expect to use the flashlight in damp areas or around water. 

Here we’ve reviewed the best flashlights currently on the market.

Frequently Asked Questions

The best 18350 batteries for flashlights are Keeppower 1200 mAh IMR 18350 and Vapecell 1100 mAh INR 18350 cells, provided that the flashlight is able to handle their capacity.

18350 batteries can typically last up to 20 minutes of highest light output on average, though the run time may vary depending on battery type and capacity.

Summary

If you are on this page, that means you already know that 18350 battery-powered flashlights are one of the best options available in the market. Be it for tactical purposes or as an EDC, you can always rely on a 18350 flashlight. 

As far as my recommendation goes, I rank the Nitecore MT10C as the best 18350 flashlight from the above-listed options. It offers you versatile light settings, great run times, extremely portable, durable and much more.

No matter what your choice is, I hope the above reviews and buying guide will help you choose a flashlight to your liking.
