No problems experienced
April 21, 2015
These excellent quality cells are performing just fine for me. I cannot offer a high-tech review with discharge graphs, etc., but I can say these are running my lights and the lights I gave this Christmas as gifts without any incidents. In average use, these go a long time between charges.
Pros:
High quality Attractive design Working fine for me - no incidents or problems
Cons:
None

Olight 18650
March 21, 2015
Received one with my Olight S30R light and liked it's performance so bought another for a back up. I Quickly started using it on my Nitecores (MH10 and P12) because of the good run times I was getting with the S30R.
Pros:
easy/quick charging, good run times value for the price
Cons:
none

Olight 3400 mAh battery
February 18, 2015
Like most of these batteries only time tells of the quality and true specs of these 18650 batteries. Battery seemed to charge great no issues, ran it in my new Nitecore P12 and it seems to give me good run times. Will have to truly put it to the test against Nitecore's light specs, to see if i'm really getting any better run time than my Efest batteries. So far so good, that's about all you can say about any battery you just purchased.
Pros:
Comes in choice of small hard case, or retail package ,same price pretty cool little extra !
Cons:
None so far

Olight 18650 3.6V 3400mAh Rechargeable Li-ion Battery
February 17, 2015
I've had these about three months and use them daily. They seem to run as long if not longer than the other batteries that I have, that cost nearly twice as much. A great battery at a great price.
Pros:
Price Long run times

Very High Quality, Top Performer
February 11, 2015
I concur that the Olight 3400 mAh battery is a keeper. Plenty of reserve power and it has the over-voltage cutoff circuit for safe recharging on rapid chargers. All my spares and replacements will now be the Olight.
Pros:
High Quality Energy-Dense at 3400 mA Protective charging circuitry
Cons:
You will pay more for the above pro's, but it is worth it.

A tie for first place
January 13, 2015
I tried this battery out and decided to compare it to my previous standard Nitecore 3400. The first issue was to determine how to measure the "value" of the battery. First step was using a meter on 4 flashlights from the same manufacture to see how close the power consumption was from light to light. It turns out they varied a lot. Ignoring complicated math. I saw up to a 5% variation between the same make and model LED light. So I used a resistor to provide the draw on the battery. To set a baseline I tested 10 3400 Nitecore's. I then did a quick test using the same equipment on these Olight batteries. Statistically the performance was too close to tell which one was on the test bed. I can easily accept that in any given application one or the other is better, but I doubt anyone can predict which will be 'best'. So as far as I can tell... this button top battery is as good as the 'best'. I do believe that there are many inferior batteries out there, but this is a top choice. I will be buying them or nitecores based on price
Pros:
Top notch high drain battery
Cons:
May not fit a particular flashlight. A big guy!

Super Battery
January 6, 2015
I tried this battery after noticing poor performance from the four Ultrafire 3000 mAh batteries I purchased over the Black Friday promotional period. This prompted me to do a run time test. The light I used is supposed to run 3 hours continuous with no step down at the medium setting of 250 lumens on two 1500 mAh CR 123A batteries. Remember high school physics. Two batteries in series double in voltage, not capacity. Results: Olight 3400 mAh battery ran four (4) hours at 250 lumens*; Four each of the Ultrafire 3000 mAh batteries. Best of the Ultrafires was 55 minutes. Worst of the Ultrafires was, 29 minutes; Energizer non rechargeable, 1500 mAh CR 123A cells 2 hours 10 minutes. *I stopped the test on the Olight battery at four hours. The light still stepped up to full power after 3 hours and 45 minutes. At four hours it would not step up but it was still constant at 250 lumens. It probably would have gone another 15 to 20 minutes or more. Regardless, point proven. Olight battery is super.
Pros:
Great run times, lives up to what you would expect
Cons:
None

My First 3000+ mAh 18650's
December 13, 2014
I have previously had 18650's with about 2000 - 2600 mAh's, so these are my first 3000 batteries. In the short term so far they appear to be doing everything they should be, with noticeably long run time on some of my lights. Will report back in a year or so and see how they go long term (that will be the confirmation) never know by then maybe we will have 4000 mAh's? Still not sure why they are rated at 3.6 volts when all other 18650's appear to be 3.7 volts?
Pros:
3000+ mAh's what more could you want
Cons:
Slightly oversize to other 18650's, fits all my Olight lights and most other current "brand" names but is a tight fit in some of my older devices.

These Olight Rechargeable batteries are fantastic. I use them on hunts and fishing at night. They run long and do not give off the heat others do. Great Buy!

Dependable
July 12, 2014
Finding a good 18650 battery at a good price can be a challenge. There are a lot of questionable 18650 batteries offered for sale. But, now Olight has their own brand of batteries, you can be assured of a quality product and a good price. I have several Olight 18650 batteries and have used them in different lights with no issues.
Pros:
Nice blue color
