What is the best 18650 battery?

The best battery depends on your application. A high capacity rating is good for long duration applications like in electric vehicles and flashlights. On the other hand, a high discharge rating is good for high power applications like in vaporizers and power-tools.

Sometimes the size of your batteries are important when building a pack or fitting them inside of a device. Weight is a good way to quickly check whether your batteries are authentic. Chemistry will tell you how safe the battery is, and what kind of protection circuitry you will need if any. Panasonic is the market leader, but Samsung, Sony, and LG all produce very high-quality cells.

What is the best battery for vapes and mods?

In our expert opinion the best battery for vapes and mods is the Samsung 25R. It has a great balance of capacity (2500 mAh) and power (20A max. continuous discharge). It has a proven track record and is considered safe to use in high pulse applications.

Are any 18650 batteries rated higher than 30A?

No. The highest continuous discharge rating for any 18650 battery is 30A. Some companies claim higher ratings like 40A or 60A. These are however based purely on pulse discharge ratings or fabricated out of thin air.

Also note that pulse ratings are completely meaningless without noting their duration. The Samsung 25R for example has the following pulse specifications when written correctly: The 25R can safely be discharged at a continuous 20A (amps). Pulse discharge levels are [95A - .5 sec, 65A - 1 sec, 40A - 5 sec, 30A - 6 sec].

What is a rewrapped battery?

An 18650 battery is a set of chemicals inside a protective steel case. Then PVC shrink wrap is applied over the steel case, which gives the 18650 its color. Some companies buy cells from large manufacturers like Panasonic, and rewrap it with their own custom-branded PVC tube. The following companies rewrap cells:

  • Efest
  • Vamped
  • Keeppower
  • AW
  • Ultrafire
  • Trustfire
  • Orbtronic
  • EH
  • GTL
  • Robiton
  • Imren
  • MXJO
  • Nitecore
  • AWT
  • EagleTac
  • AmpMax
  • Basen
  • BattEnergy
  • EnerPower
  • Fenix
  • Intl-outdoor
  • Redilast
  • Xtar
Rewrapped cells can be used for good or for evil. Some companies add value by providing quality control or adding protective circuitry when needed. However the darker side is it opens the doors for deception - exaggerated or completely fabricated battery specifications.

What is an 18650 battery?

Most people are familiar with the A, AA, and AAA battery sizes, but have never heard of an 18650. Manufacturers that produce lithium ion cells have a special battery called the 18650, named after its size as it is 18 mm wide and 65 mm tall. The nominal voltage is more than twice that of AA cells - at 3.6V each.


Lithium-ion is the battery chemistry with the most potential and fastest growth. Out of all metals, lithium provides the largest energy density for weight.

Commodity cell

The 18650 is the most economical of all li-ion cells. Standardization from the laptop and electric vehicle industries continues to drive the price down.

Low maintenance

Li-ion is a truly low maintenance battery that has no memory, requires no scheduled cycling, and has a very low self-discharge rate.


Lithium ion is part of a new generation of rechargeable batteries that has been in development and improving since the 1990s.

Research & Development

Researchers are constantly improving lithium ion cells. New chemical combinations are introduced bi-annually and progress is made quickly.

Very high current applications

Specialty applications like vaporizers and power-tools have created a line of batteries with very high amperage discharge ratings.
