Can you use an 18650 BRC in this?

No the 18650 is too large the 14500 will work as well as 1 AA battery. I have several of these flash lights, buy it you'll love it.

No, Fits a standard AA. The 18650 BRC is too large.http://en.wikipedia.org/wiki/AA_batteryhttp://en.wikipedia.org/wiki/List_of_battery_sizes

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.

I have no idea what a 18650 battery is, but from the other responses, it looks like the answer is , NO.

I have the older model only with 3x AAA battery, However they do not last long, can I use the single 18650 battery in my model?

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

CR-123 are not to be recharge may explode or catch on fire. the batteries need to say rechargeable before you can do so the 18650s has a circuit in the battery to protect you against this.

Yes as long as you take out the plastic sleeves for the 18650 if your light has them

Yes it can handle both those sizes in addition to 18650 safely. The newer model has springs going farther up than what is pictured.

Hey there =), Neither, the 18650 3.7V is its own type battery. It is used for certain devices and i use them to power my Cree Flashlight.

Both the red and the blue did run 1/8 inch shorter than my factory brinkman flashlight battery 18650. But the spring connection in the negative end of flashlight took up the slack. If your negative end of what you are putting it in has a spring you shouldnt have problem. If it has a tab connection you can bend it forward slightly an be fine. Never hurts to try. They make these replacement batteries smaller for a reason. Little smaller fits all. Too big fits none. They will probably fit 90% of applications.

No. While the 26650 is the same length as the 18650 it is considerably larger in diameter. However, they're both 3.7v and if size were not an issue one should be able to use either size.

No, 18650 won't fit but 16650 will. Flat tops should work if they are long enough. I have 16650 button tops for mine, works fine.

They are not a normal size battery. They are all over larger than AA, more like a longer slimmer C battery. They are very specialized for specific items. All the information provided on the battery is in the name: BRC 18650 3000 mAh 3.7V li-ion made by UltraFire.

I don't think you can charge 26650s on here. I only use 18650s, but you can use any of the three settings to charge them. From my understanding, the slower you charge it, the longer it last, so I always charge mine on the slowest setting, unless I'm in a crunch.

no, you can do the opposite with an adapter 18650 with adapter will replace a 26650

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

No, but you can use the CR123A, just don't use more than 3, and of course the 18650, and 3 of them as well.
