Hands down Best 18650 Battery I have used in Flashlights and Lasers
November 3, 2018
I was buying 18650 batteries some time ago from other sellers and they never seemed to put out what they claimed. I believe other sellers where selling re-branded Chinese cells. I only purchase batteries from Battery Junction and all there batteries that I have purchased put out or exceded specified mAh. I have a battery analyzer that will discharge then charge battery and after that show mAh. Every battery from Battery Junction is the REAL DEAL. Do not waste your time with other battery sellers for these guys sell 100% authentic cells. These Panasonic NCR 18650 3400mAh seen to last forever and put out lots of current for my most demanding searchlights. Thanks Battery Junction for being an honest seller that watches out for us. Guys buy with confidence from BJ.

Replaced a laptop battery with these.
March 1, 2022
In an effort to save some money and learn a bit more about constructing battery circuits, I purchased these batteries. Worked very well and operated without issue. Definitely worth the price, but depending on your project it may be extremely difficult without performing damage to the battery itself if you were using basic soldering hardware like I did.
