Went bad after 5 cycles

March 25, 2023

Used in shortwave radio, used max 5 cycles and now the radio cuts out due to probable high internal resistance.

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

May 21, 2021

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.
