I don't think so, but you really aren't risking much of ruining the light as they are quite affordable. You definitely won't hurt the battery trying.

hi, the 18650 battery is for the t6 which is a bigger battery and will not fit and 14500 is for the mini cree q5 300

Yes, you can use the 3.7v. I use a rechargeable 3.7v, and it actually produces a brighter light than a standard AA lithium.

The TRUTH is UltraFire DOES NOT make an 18650 over 3000mAh. Go to the UF website and check this yourself. Dishonest seller buy cheap low power seconds of anything they can get repackaging them with phony major brand name labels. Nobody makes a "real" 18650 over 3600mAh in the first place they just sell them with fake labels to get people to buy them.

Personally, I wouldn't. I could be wrong, but most of the better quality 18650's are protected, and on a light this nice, I just would not consider using less than a great battery. Not sure if that answers your question.

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

If your unit comes with the 18650 Battery, then no. If it comes with the 14500 battery, then yes you can use AA batteries. The light will be not as bright 1.5 volts ver 3.7 volts. but the light is still good.

No. They are 18650 batteries. Probably removed from a used up laptop battery.Ultrafire batteries are crap. You might get lucky, and get a good one, probably not.

It should work. It works great for my fenix pd35. The battery is a little longer than most 18650's but if there is a spring in the flashlight there should be plenty of play.

I have found that the 18650 3000mAH batteries work very well with it. You can get the inexpensive charger andd use them over and over again or charge up an extra set for when the ones in the flashlight drain down. The specific brand I use is UltraFire batteries.

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.

Unfortunately, the 18650 rechargeable battery will not fit in the flashlights. Mine just arrived around a half an hour ago, and tested them with the 18650, which sticks out from the base of the flashlight about a quarter of an inch. I'm not sure if this post was referring to an older model, but it doesn't fit the current.

No the one you have is smaller, and can also use a rechargeable 14650 lithium ion battery. Regular AA only puts out 1.5v the lithium ions put out 3.7v. It probably also uses the Cree q5 LED, this one uses a Cree XML T6 LED which is brighter. This one requires a 18650 battery, a AA will not work, although there might be a 3 AAA adapter for these. There is also another version that looks like this light but is larger and uses a 26650 which is even larger than an 18650.

Yes, according to my manufacturer, an 18650 Lithium-ion battery will work in this light. Thank you for your question and your purchase. Have a great day!Don R.

it use UltraFire BRC 18650 3.7V "4000mAh" Li-ion Batteries Battery or any of these batteries: 18650 4000 mAh 3.7V Li-ion Rechargeable Battery. This is a amazing high lumen cree, but the battery consumption is high.

You can use 3 AAA, but need to buy an adapter. Search for "18650 adapter aaa"

I bought the ultra fire 6800mAh, 3.7v, 12 of them with charger here on amazon. but the light seems to have the room for the slightly longer ones as there is only about 1/8in differance

Probably depends on where you buy it from. Different vendors use different batteries. Mine are the ultrafire. They seem to work OK. Initially, i did not leave them in the charger long enough and was somewhat disappointed.When you use the charger, leave the battery in until light turns green and that will fully charge the battery.

It will not work with 18650s... The flashlight is a smaller diamater than a 18650. It operates on a single AA battery (at reduced performance) or a single 14500 battery.
