can I use a regular aa battery in it .

No dude you need the 18650 batteries. The regular aa batteries are too small. The 18650 batteries are fatter and more powerful. The good thing is that it only requires only one 18650 batteries and they are rechargeable. My suggestion would be to buy a pair with the wall charger, and Carry the second battery as a backup or replacement.

I have a lot of different UltraFire flashlights. All are very bright. if the model does not use the 3.7V Lithium battery, the model is designed for three AAA batteries. I never saw a model that uses AA batteries.

NO !!! You need the 18650 batteries. The regular AA batteries won't work, they are too small lengthwise and will not work.

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.

It's a AA battery. So no, unless you have your own rechargeable AA battery.

Those batteries can replace regular aa in certain items only.They give more power than the regular aa but have to be used only in compatible items.For example they are great in this flashlight http://www.amazon.com/BBQbuy-300lm-Flashlight-Torch-Adjustable/dp/B006E0QAFY/ref=sr_1_2?ie=UTF8&qid=1355173097&sr=8-2&keywords=mini+flashlight

Yes AA should fit. I've thought about replacing my batteries with newer batteries.

It could use a regular battery but comes with a rechargeable battery, which works fine.

You can only use the rechargeable battery, there are no areas on the cube where you can insert AA batteries

Yes, they are AA like any other, Not rechargeable so you can use them in anything that takes a normal battery. They will just last a lot longer. Hope that helps.

It already comes with Lithium ion battery, which is rechargeable. So like wise the battery slot is also designed for the Lithium ion battery, which is square in shape. I believe AA battery will not fit in this

Yes. You can use regular batteries as well. I am currently using regular batteries on the two I have because both rooms are a bit dark and the time shuts off on evenings when it gets darker.

No, mine had standard AAA batteries. I presume you could put rechargeable batteries in and then remove them for recharging but recharging with batteries in situ is not an option.Mark

I actually didn't use rechargable. I used regular AA and it worked perfectly for me!

I only use regular batteries, I honestly do not know about that, sorry. I guess we'll have to do some research.

The battery last for a long time. A couple of days on standby while hunting. But I was disappointed that you can't use regular "AA", only works with power pack.

No. Takes 2 regular AA batteries. If u hv some (recharge-ables) I'm sure they'd work fine.

AA's will not work. They don't fit. This uses a crazy large battery that is only made to be rechargeable.

You can use rechargeable AA batteries, but it does not come with them, just regular ones. And the voltage is 120v standard US outlet.
