*Please NOTE these button top batteries are 2-3mm longer than a standard 18650 cell. (flat top, unprotected). The button top is commonly required for flashlights, doorbells and other devices.
Samsung 25R Unprotected Flat Top Cell

This is arguably the most widely sold and respected 18650 form factor size cell on the market, still today. This cell is of very high quality and has a very economical price point to book-end it. This is an excellent balanced cell in terms of performance and reliability. Also this cell has a very good equilibrium with a moderate-high capacity of 2,500 mAh in energy, while having a high maximum continuous discharge/drain rating of 20 amps (Without any temperature cut involved). This cell is very stable, even when it's pushed to its max rating. This cell has about everything you could desire in a Li-Ion cell, as you can see from some of its attributes. It has many uses such as: power packs, high-output power banks, BMS's, power tools, and high powered flashlights as well. This cell has a much safer battery chemistry makeup than cells from the past, which make it more stable and much safer. This cell is often classified as a "Goldilocks" cell, because of its versatility and all of its attributes. This cell has passed the test of time and checks almost every box that you can reasonably image. There is no wonder why it has such a venerable history and a consumer favorite.

4 of 5 Seem genuine, will soon be using it to veriy September 21, 2020
Reviewer: Arthur Hensel from Scottsdale, AZ United States  
There are so many Chinese fakes out there.  The first thing I did was weigh the batteries and charge them.  The weight was right in line with Japanese 18650s.  As soon as the Chinese batteries currently in my headlamp die, I will use the 25Rs and be able to compare life.  I temporarily docked them one start until I use them.

5 of 5 Excellent Batteries! September 14, 2020
Reviewer: Brian Duty from Saint Charles, MO United States  
These batteries are performing perfectly.  I've ordered several times from 18650BATTERYSTORE because I know that I will get a genuine name brand item.  Most of my shopping is done on Amazon or EBay, but when it comes to batteries I want to be sure I'm getting what I pay for.  The price was amazing also!
