For the Fenix UC 40,what type of 18650 can use, flat top or button top; protected or not protected

Good Morning, I am scared to say that it will take any battery but as long as its a quality 18650 you should be safe. I just checked to be sure and dropped a few different style 18650's into the bore and all worked. The light comes with the Fenix ARB-L1t 3400 + I am tossing in 2 Xtar CR123a's. Thanks, Shane

18650 batteries are "approx" 18mm W X 65mm L, this particular battery is 64mm LThey easily, and safely fit in Vamo V3 and V5, Lambo, Sigelei, and SVD mods. They are unprotected so they should only be used on protected devices. I enjoy at least a full day of use out of these batteries for the primary reason they were purchased, which is e-cig mod use.

What is not in the description is that these batteries are protected. In my vape I can't use them since I run sub ohm coils. And the batteries don't fit in my itaste vrt. To tall with the button top. The charger works perfect and the batteries last a long time when I use an atomizer that has a 1.2ohm or higher coil.

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.

as in if the top is COMPLETELY flat well no , tis got a niple at the top but its almost flush with the edges , but have to to say its a really good battery , fits most items and really good quality but if price is a problems there is the Olight 3400 mah 18650, i hear they are good quality as well and cheaper, they seem to have the same design as this battery too

18650 type. Get some quality batteries like Sony VTC5's, avoid any of these you can see on amazon called Ultrafire or anything like that.

The MagLite Mag-Tac LED Flashlight - Will not accept a 18650 Battery. The MagLite Mag-Tac with the crowned bezel has a strobe function.

Every mmod is made different. I have 3 mods and one fits snug the other fits loose and one still rattles a bit on a connection. Its just the way they are due to them being un regulated. If you want a sucure snug fit every time, get a variable voltage box mod that has a battery tray made for the 18650 batteries.

I'm not sure what the best are. The batteries provided were one use of course. I've got ultrafire 18650 rechargeable right now.

It comes with a plastic spacer for the 18650 batteries to work. I have only used one type at a time but they both work. I see more light output with the 26650 batteries. I suggest buying some even if you already have some 18650s. I have the Fenix TK 75 which is comparable to this light with 26650 batteries. This one has more spread, the TK 75 has better throw. Lumen ratings are way off but this is a good light for the price.

You need protected cells in all high-current flashlights such as this one. With batteries in series, it is impossible to protect each cell from one circuit - it has to be in each cell.

Hey, it uses cr123's (2) . 18650s are just slightly too big to fit in the tube. It's a pretty good flashlight ; however, I gave mine to my brother. For pretty much the same price the Fenix PD32 UE or PD35 are vastly superior lights in lumen capacity, function and user interface, as well as build quality.

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.

I got the light and a holster. I have to disagree with William - I noticed no difference between Ultrafire 26650 and Samsung 18650 (I guess Ultrafire overstates its capacity). Also no increase in brightness by using 3 batteries - just more heat.

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 got mine from here on Amazon. The one I purchased was "Protected 18650 Rechargeable Batteries Plus Charger (2pcs)".
