Need a pair of 18650 3.7v for a CREE XM-L XML T6 LED 5000Lm Rechargeable Headlamp. Told to buy "Ultrafire" batteries, but don't trust.Would these do?

I've used them for over a year in a Fenix flashlight and they've been perfect. If they are the right fit then I'd highly recommend them.

These are among the best high drain batteries. They should perform quite well for a headlamp.

I use Ultrafire (from China) and Panasonic (from Japan) in a number of flashlights. I have charged all of them at least 10 times each, and can't really tell any difference between them. They all charge within 12 hours, pretty slow, but hold the charge for a long time; I'm talking about many months if you're not using them. Hope this helps.

Quite happy with this purchase. Batteries are good and holds the charge for a long time (more than a few weeks). I have them on a Nitecore Flashlight MT40 which I only use from time to time.

Just saw your response about length. 18mm is the diameter, 65mm is the length. Some batteries have an electronic protection circuit at the end making them 2 or 3mm longer. The springs in the headlamp should compress enough to accommodate them.

Yes, the 3.7v batteries will work. They are bigger than the AA and AAA batteries. And more powerful. Some of these LED flashlight have AAA adapter. But yours doesn't. There not recommended anyway.

They should recharge with no problem. A 18650 is just a high-output AA battery. Normal AA batteries are around 1.5 volts. 18650's are between 3.5 and 4 volts. Just be careful what you put the 18650's in, as they might burn up your flashlight or radio if not rated for the higher voltage. Hope this helps.

I have just cause I had them from another light that I killed and it didn't seem to make a difference. I keep 18650s in mine just because of how much I use it around the house. Just bear in mind that it is NOT 1000 lumen by a longshot.

Depends on if it's an XM-L T6 like it says, or something else. The first one I got wasn't even the same class of Cree bulb, the second was an XM-L U2. From what I've seen online the U2 is around 5700k and the T6 is around 6500K. This also seems to match up between the U2 I got here and another light I have with an actual T6.Of course, the permanent button memory and lack of adjustable focus kill this flashlight for me. It's bright, but I don't recommend it.

There are certain Cree flashlights & other Cree lights that use that type of battery. U just have to search which ones. Hope this helps you.

I use them in my mod, they are the longest lasting batteries I own. just make sure your mod excepts 18650's.

I have several 18650 batteries. They are all the red UltraFire batteries, but I'm sure they would be the same size as yours. The single red UltraFire 18650 battery is too long and too narrow for this flashlight. At least the "AAA" batteries it takes are easy to find.

Matt, Buy the Trustfire 26650s if this is the 7 or 11 led torch. I own the 7 @ 8500 retina melting lumens. It will work on 2 or 3 18650s or 26650s. I use 3 26650s an they last hours on high. This beast lights up a whole acre! Don't forget to get the universal battery charger.Steve

Hi. The replacement batteres are Li-ion rechargeable 18650. These are 3.6v, should be 3000mA.These are readily available with a charger through Amazon- I bought several sets and have had good luck.

Great flashlight! But unfortunately it came with two, very lame, COUNTERFEIT UltraFire batteries. They say 3000 MAh, but are probably only 1000 MAh. This is also supported by the weight of the batteries. A normal 3000 MAH Lithium battery weighs in at 1.5-1.7 oz. These are only 0.5 oz. Also, I sent a picture of these batteries to UltraFire and they said that it is not theirs.

You can use 18650 I use them and mine has not presented any problem. It will use 4 1825 with with sleeves . I have an 1865000 lumen with 15 cree t6 led and I have the same 18250 in it and it works super well

A reviewer on the trustfire 26650 batteries said that the ultrafires that claim 6000 mAH are more like ~3200 mAH. ymmv, but I've never seen any of the 'fire' branded batteries actually reach the claimed capacity.

Yes they are. They are closer to the size of a C cell battery but twice as long. They are the same type of cell that is in laptop battery packs. If you search 18650 you will find the batteries and chargers here on Amazon for very good prices. All the Ultrafire batteries I have bought work great. This is by far the best of the best when it comes to budget flashlights like these: http://www.amazon.com/UltraFire-WF-502B-XM-LT6-Flashlight-Clip/dp/B006LVBDNU/ref=sr_1_3?s=hi&ie=UTF8&qid=1364293375&sr=1-3&keywords=ultrafire+502b

I have a TN 12 they fit in. I looked up TN 32 and it says it takes the 18650 batteries. I also have ultrafire wf501b they fit also. These cree lights are great and really bright. Hope this helps.

you definitely want the 18650 battery. Less expensive in the long run but more importantly it is a 3.7 volt so you get more juice out of it, brighter light. I NEVER use AA or AAA if there are other options.

The correct battery is the 18650. You could also use two CR-123 batteries instead. Either will do the job.
