I've been using these batteries for years, I think ( at least for me these batteries last about five years). I have some batteries that I'm still using and holding a charge dated 07-06-2016.

no where close to 3000 mah
April 21, 2021
When I got mine tested them got 900 mah out of one of the 2 I bought was curious on if they would give me the 3000 mah they were on backorder as well the second one I test came back with only 700 mah quite a trash battery avoid it.. used a opus 3400 and a xtar dragon to double check my results.. gave them 4 hours of resting time between charge and discharge cycles to let them settle. Even did it at 500 mah charge rate.

Not a fan, won't buy again
January 8, 2021
I bought 4 of these. One never took/held a charge (using a Opus and Nitecore charger). The other only fit in some of my 18650 flashlights, and were tight fits in battery backup cases I have. Maybe I got anomaly, but the 15-20 Nitecore, Olight, EBL, and other brand batteries, these are the only to fail right off the bat.

Great Batter
December 24, 2020
I have tried a lot of 18650's but these have been the best so far. Long lasting and durable (other brands have gone bad in less than a year). I only use 18650's in flashlights, so can't say how they are for any other devices.

Solid battery for the money
July 22, 2020
I purchased a couple of these a while back for an Olight Triton that is not often used and the batteries work well, holding a charge over time. Holding a charge over time (self discharge) seems to be the problem with these rechargeable 18650 batteries. I have purchased this same exact battery from another vendor (that was a mistake so please order from battery junction because they have great customer service and nice people in general) and the ones purchased from 'vendor b' have problems holding a charge so when I grab my light its dead. So either this brand is counterfeit from other sellers (I have read in a few forums that is likely the case) or is subject to bad batches. So buy these from here knowing customer service will take care of you if you need it.

great battery for the price

I ordered a laser from a Chinese company and it took 3-1/2 months to get and it arrived without a battery. Of Course Battery Junction was right there with the unique battery I needed at a great price.

Do not last at all
February 5, 2018
Don't expect to get too much from this battery. It doesn't last at all and won't hold a charge after a few months. That's been my personal experience. You're better off buying a pair of CR123A lithium batteries - they would last longer! Seriously.
ProsKinda cheap.
ConsYou get what you pay for. And in this case, probably not.

Fit the bill
November 30, 2017
I needed to replace the very poor quality 18650 that came with a flashlight with something a bit better. This fit the bill nicely. With purchasing two of them, so I can have a charged spare, I should be in good shape to keep things illuminated when necessay.

Not that great
November 2, 2017
I purchased a UltraFire 3000mAh battery for my Nitecore HC60 and noticed after about 3 months that the level 5 (highest setting) would not work even right after a charge. The battery seems to not be holding the voltage when loaded. This will probably be the last battery I purchase from UltraFire. NOTE: I was using a NiteCore D2 charger.

Excellent battery
August 7, 2017
This battery outlasts every one of my "advertised" higher amp batteries (including 6,000 and 9,800)...BY FAR. Compared my 6,000 and 9,800 to this Ultrafire 3,000 (using identical flashlights) and the Ultrafire lasted more than 4 times as long as either of them.
ProsBest battery on the market. Make sure you get the "protected" battery to ensure you do not over-charge.
ConsAbsolutely none

I bought one of these and it sure didn't seem to hold power for very long-at least not like the hype would make you think. I found these batteries reviewed on YouTube. They didn't seem to like them very much either. I'm going back to spending my money on Samsung.

My experience with these rechargables has been nothing but positive. They are lighter than the 2500mAh rechargeable batteries that I own produced by the same manufacturer, and they run longer, meaning less frequent trips to the charger. The appearance of the packaging has improved as well. When you take into account how many CR123's this one battery takes the place of, the price is very reasonable.
Proslow weight , high capacity , improved appearance

Working Good for My Purposes
April 21, 2015
I don't run my lights on turbo for extended minutes, so I can't say if these would step down like some users have reported. I use my lights for brief scans, and only use turbo mode outdoors to scan a large perimeter around myself for safety, then usually step it down, especially if I'm going to be walking and needing it on for a while. I can say that when I had two of these in the same light, one of the two seemed to discharge a little quicker than the other, but not severely. That might indicate spotty quality, which I see reported with these less expensive batteries. My experience so far has generally been good. I've had them since November, 2014, so that's not a really long evaluation period. So far, I like them for the price.
ProsLess expensive alternative which will get you up and running until you can get some premium batteries
ConsVariance in quality? Maybe. Large diameter could be a problem in some lights - so PLEASE READ the description.

In the recycling bin
December 30, 2014
I bought four of these cells during the black Friday promotional time period around Thanksgiving along with Nitecore D2 charger. I began using them in my lights and noticed the lights quit much sooner than they do when I run them on the Titanium Innovations CR123A batteries sold by Battery Junction for $1.00 each. This prompted me to do a somewhat scientific test. I began by charging the batteries fully. The D2 indicates the fully charged voltage and I verified this with a multi meter. Next I switch on NFL pregame, installed one of the four batteries and set my light on medium. According to the light's specification, the light will run 3 hours at a steady 250 lumens. The light quit after 26 minutes. Long before I finished watching the play off bound Patriots lose what turned out to be pre-season game against Buffalo, I had tested all four batteries and all four powered the light for 26 minutes or less. I had to do a post-Christmas run to the town dump and recycling center so I took that opportunity to drop off the four in the battery recycling area. $35 wasted. On a side note, the Nitcore D2 seems to work well so far. Now I just need to find some batteries worthy of keeping.

December 21, 2014
I purchased 2 of these batteries. I ran one on high at 600 lumens for 3 hours straight. It held up really well. The other battery i received is a dud. I have attempted to charge it in my nitecore i2 charger and nothing happens no lights light up. The charger is good because the good battery works in both battery charging bays. The bad battery does nothing. The bad battery wouldn't be worth returning when including shipping costs.
ProsWorks good if you receive good batteries

Powerful batteries that cause my Fenix flashlight to stream a bright white light and makes the dark go away. They charge easily and hold a charge better than average, but are still a little pricey.

Very Good
December 17, 2013
I just got these batteries & Charged them yesterday and and started my testing today, using my \"Innova\" tester that puts a load on, when testing, Reading before test was 4.08V.. Put my \"Nitecore\" SRT6 930 Lumen on turbo for 19 minutes, then tested the voltage again, with a reading of 3.93V.. I feel these will hold up pretty good..Battery worked just fine.. I\'ve read about complaints about these type of batteries being out round, and that is true an average of .012 mainly located at the top (+) were the overload device is located(.715-.727), but a device made for #18650 has more than likely compensated for this.. Even Alkaline Batteries like AA (EverReady & Duracell) are out of round an average of .006..

Poor Quality
March 31, 2012
I\'ve tried to make these work for me, but unfortunately, they just can\'t handle the higher current enthusiast lights. These will probably work fine in lower draw 18650 lights, but in high current situations (IE: TK35 Turbo, TK12 Turbo, NiteCore TM11 High) they go into protection in less than 3 minutes. I\'ve relegated them to backups, but it\'s unfortunate at this price.

Bang for the buck
May 19, 2011
I bought these batterys for my olight M20 and Tk11 and they work fine. Depending how much I run turbo on them these cells last for a long time. Esp now since I\'ve upgraded to the new XML lights thats come out. I plan on buying more maybe 4 more. Did I mention you wont have to buy new batteries every few weeks.

These are excellent batteries I use them in my fenix TA-21 with only 1 modification to make them fit better. I remove the top 1/2 inch of outer label at the positive tip end to make it slide in better. It\'s not the flashlight or the batteries fault it\'s where the battery is seamed and the label adds just a cpl thousanths of an inch in the one spot to make the battery too tight to remove easily. These are quality LI-ion\'s and worth every penny to have the power these batteries store

I got a pair of these batteries to go in an Olight M30 and they keep my Olight bright and working for a really long time. I use my light about 15-20 hours a week (not consecutive hours) and with a full charge they last me a weeks time.
