I think that you would like this flash light. Very strong light. I don't know about the battery yet, haven't needed to replace. I don't think that it is rechargeable Just check the specs. KW

No, 18650 battery is too big for it. The flashlight is Powered by: 1 x AA / 1 x 14500 3.6v Battery (NOT Included) as advertised. If you need 14500 battery, please search B00FYMPSGA.

No, the 18650 is both slightly longer than two CR-123a's and larger in diameter. Also, they run 3.3-4.2V as opposed to 5.6-6.4V total for two 123a's - the LED flashlight must be designed to accommodate them. Many two '123a cell lights made in the PRC, like my Olight M21 & M22 and Fenix PD-35, will use them - and work better, too. None of my 2-cell US-made Surefires will fit them - the body tube's ID is too small.

Sorry. I have the 44901 lithium not the 44900 std battery. FWIW. Amp draw has to be marginal Best flashlight I've ever owned BTW.

No, this swich does NOT fit the ultrafire 502B. I have that exact model of flashlight here in front of me and I repeat that this swich will NOT work with the ultrafire 502B.

I think it should work based on measurement and specifications but it it isn't made for them. This charger is more for the larger diameter batteries like the 26650. Those batteries are about an inch in diameter and the specification on your 18350 is 0.70 diameter. The contacts on the charger close to about 1.25 inches and your 18350 specification is 1.5 inches, so it should fit based on length. In general the 18350 is too small to fit properly in the battery cavity in this charger so it will rattle around in the bottom and not make perfect contact with the terminals. But I did put one of my 18650 batteries in and it started to charge. I think the 18650 is just a longer / higher capacity version of the 18350 so in conclusion, I think it will work if you are careful, but be a little hard to make sure the contacts or making proper contact for charging.

Well in the first place, I doubt you will find a true 4000mAh 18650. Panasonic has a 3400mAh and that is the highest true 18650. Anyway to answer your question the battery will be heavier then a 3000mAh. However, some 18650 have a PCB for overheating, these batteries will be longer. FYI; UltraFire does not make an 18650 over 3000mAh. These batteries pictured here are counterfeit and Amazon know it. Do not buy. A true UltraFire 18650 battery weighs 1.5 ounce (42.5242847 Grams). The Cathode plate (negative end) is brass in color and has their trademark stamped on this brass colored plate. This trademark stamp states Ultrafire (not UltraFire) with two fire flames located directly above the "e". The Maximum mAh (milliamp hour) is 3000. Any UltraFire 18650 battery stating that it is over 3000mAh is a counterfeit. Any UltraFire 18650 that does not have the above description is a counterfeit. The range's of the UltraFire 18650 batteries are 3000mAh, 2600mAh, 2400mAh and 1200mAh, http://www.ultrafire.net/shownews.asp?id=60 http://www.ultrafire-shop.net/page3.php http://www.ultrafire-*shop.net/data/storage/attachments/94a73d230e2445b0feea1ef30f550de0.jpg *The above web site is a CR123A not an 18650 but this is how the Cathode appears on the 18650. By the way, I am in no way affiliated, connected to or know anyone affiliated or connected with UltraFire. I am a consumer that is getting tired of being ripped off, lied to and cheated. So I decided to do some research and this is what I found.

Not sure. First make sure your flash has the proper connection for the adapter of the battery pack.

I did a lot of research and watched a lot of videos when I bought my flashlight. The batteries will definitely work in your flashlight.

Michael...it looks like it will fit just fine. it just slips over the flash portion. I'm sure it would work well.

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.

the 18650 will not fit this flashlight. i own both this flashlight and the slightly larger ones that use the 18650 lithium rechargables. the smaller light uses 14500's or AA batteries...they are the same size. 14500's are highly recommended as they put out a lot more light and are 3.6v instead of the AA's which are 1.5v

The batteries are standard diameter 18650, but have the extended button tops which may be long for some flashlights. Not sure on your particular flashlight, but they still fit in mine even with slightly longer overall length.

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

the use of a 18650 battery requires a separate extension piece to accommodate the 18650s length, the one I acquired and works with this flashlight to be able to use the 18650 battery; http://www.amazon.com/dp/B00DAXPGNK

http://www.amazon.com/gp/product/B00AQPZM7U/ref=oh_details_o02_s00_i00?ie=UTF8&psc;=1I bought these ultra fire in the link above. Just as long as you charge them all evenly and dont mix batteries youll be fine. Oh and by the flash light a great! The quality surprised me. Really bright, I can compare to NITECORE TM11 but way cheaper. So when you drop it you wont care to much

Well 4000 is bigger than 3000.... But there is currently no such thing as a 4000mah 18650 cell, and the official UltraFire website does not list these, so they must be fake.

No. A 18650 battery is much larger. This one accepts a 14500 battery which is explained in the following article; http://lightsngear.com/what-you-need-to-know-about-the-14500-lithium-battery/
