Work well enough, amazingly cheap
October 29, 2021
First of all, there is no indication on the batteries themselves that these are made by Samsung. That said, they seem to hold there charge well and I have yet to have a problem with charging them. They are the just about the cheapest 18650 batteries I've found aside from brandless crap on Amazon, and even then the price is competitive. I think I'll spend a bit more and get the nicely branded batteries in future, but I don't regret buying 4 of these.

Cells ok, Protection questionable
May 28, 2021
I bought 4 of these. Out of the 4 only 3 would work at all. One of them, I had to cut off the protection board because It wouldn't allow anything over a few hundred milliamps of discharge current. The cell in it works fine without the protection board, but if I wanted an unprotected cell, I wouldn't have bought protected ones. After a few cycles, I am now wondering if I am having trouble with a second protection board limiting charge current really low for some reason? Perhaps as low as 100 milliamps. Maybe I should just remove all of the protection boards and use the cells carefully, that wasn't my intention, but seems like the protection boards aren't very good on these.
Received quickly

Received batteries with the same information regarding number, voltage, & amps but the unit itself was too long. Web site warns of +/- 1mm but the items I received measured 4 mm too long.

Taller than a vap mod 18650 style battery.
May 4, 2021
Good battery just no use for a vape mod. The normal flat top and most protected I have purchased are all the same height. These are slightly taller. Good battery just make sure it will fit in what your putting it into. Most flashlights are fine as the springs have room for the extra height.

Good Battery - Great Price

After 2-3 hours of charging time, the battery worked well on my doorbell camera. I bought 4 with multiple items discount, good price.

My new battery is used every night for the “dog walk”. The brightness of my flashlight has not diminished in over two weeks. I’ll be ordering another soon.

Samsung 2600mAh 3.7V battery
October 16, 2020
Bought battery to replace one in my flag pole light. The old one did not last all night anymore. It was also a 2600mAh battery. I was disappointed that the new battery did not last any longer than the old one. When I bought the light the battery lasted all night for about 10 months.

These batteries are phenominal at serving the purpose which I purchased them tp perform.
May 2, 2020
These batteries are exactly what I needed for the battery-operated item that I purchased them to power it. They are definitely holding an excellent charge while performing the power to operate my device. I am ecstatic over the cost of the batteries being very reasonably priced; when, compared to how well they perform the task(s) which I purchased them to perform. An excellent purchase! Thanks!

Works as expected

Using two in my three cell D maglite to power a 1100 lumen LED upgrade kit. I 3D printed an adapter and everything is working perfectly! Came pretty much fully charged (measured 3.6V on my multimeter). Fair price as far as I could find for a purchase of four batteries to play with.

Too tall!!
February 25, 2020
I bought these for my vape, and they were too tall and the battery lid on my vape would not come close to being shut. I had no idea that they would be taller than regular 18650 batteries. I would have returned them, but the hassle would not have been worth it. This store makes you pay for shipping, plus a restocking fee. I ended up just going to a vape shop to buy the batteries that actually fit a vape.

Excellent battery
January 9, 2020
These batteries work as well and hold a charge as long as top brands that cost 3 times the price. I have several others that I bought 3 years ago from another source and they are still going strong so I know how long they will last too. If you buy these, you will not be disappointed.

100% happy
June 27, 2019
Replaced battery in a Lezyne high-output bike headlamp with this one. The Lezyne branded battery that came with it (don't know who actually made it for them) would be down significantly after 20 minutes (causing lamp to switch to power save mode) and dead in 30 minutes. This Samsung battery charged quickly and was still running the lamp in the green after more than an hour. And the price - including shipping - was less than any similar (but not quite right) battery I could find at shops near me. 100% happy, highly recommend. Thanks, Battery Junction!
