How can this battery claim 5000mAH when the most powerful 18650 possible with current tech only about 3600mAH?

I really do not understand the content of the question. I purchased these batteries a few months ago and do not remember the amp hour claimed by the manufacture. I am a maintenance man and use my flash light every work day. After receiving the batteries, I charged them and installed. To date I have still not had to place them back in the charge mode. I really like these batteries a lot. Sorry if I was no help to you on this question. Have a great day.

Its possible because I have each one of 4,000; 5,000 mAh. They work great for me.

An swer here..when i purchased the batterys i was looking for a good long lasting battery an not a legal battle over technical stuff. Also in your question you wrote with current tech only about 3600mah. Notice the word about! You may be correct but you may not have found all the facts yet either. But beside all the technical an nit picking things it is a good battery an has served its purpose for me so far.

The writing on the battery does not indicate the number of cells in the battery. It states DC 11.1V, 48 Wh(400mAh)

Yes. It's still an 18650 which is the main part you should be looking for, this battery just has more mAh than the one you're taking about.

No, they are completely different sizes. This is about twice as fat as an 18650.

There is a performance gain by using the 18650 battery. I tried both battery options and found the 18650 to work the best. I have a couple other flashlights that uses the 18650's. I purchased a 12pk of the 6000mAh batteries and that is my recommendation. That last for ever. I hope this helps.

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

No...because 5300mAh batteries do exist yet. 3600mAh is the maximum real rating, anything higher is lying to you. Get a known brand for real mAh ratings. I have compared Panasonic 3400mAh vs "5000mAh" batteries, Panasonic lasts about 6-7 times longer, showing the "5000mAh" batteries are really 500-600mAh.

The battery comes upgraded to 5AH. I guess it's a marketing strategy, but it works.

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.

I charge 18650 batteries from 2900 mah to 3400 mah on my unit. Most all 18650 batteries are 650mm long as well as 26650. The first two numbers indicate the diameter and the last three indicate the length. Hope this helps. Ray

The AA or AAA batteries are of a different size and shape and the voltage is different. I found that you can order conversion kits, but the reviews on them are not good. The 18650 battery holds a charge for a long time and I find it quite convenient. I keep a second battery charged at all times in the event I need to replace.

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.

Hi,Sorry I can't help you with that question. I bought the rechargeable amazon batteries with it and they work fine. But I couldn't tell you if they are 5000 or 4500mAH

I personally don't own that type of battery, so definitely ask the seller, but that being said it does a great job charging my 3600 mah 18650 batteries... As long as the batteries don't require a unusually high mah charge though I would say you probably have a very good chance of it working... Plus it has a good deal of safety mechs on it to correctly identify the right voltage to charge at as well as protecting from over-charging... I would guess it's a safe bet...

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.

Patrick the best battery that I have found to use is the Orbtronic 18650 3100mAh all others I have tried have failed after a couple recharges, I have recharged these batteries 14 times and they still charge up to 4.2 V and maintain brightness down to about 2.7 v. I use the light everyday and I swap batteries about once a week. Hope this helps

I just looked at my battery and it says: 2.4v 500mAh NI-MHBatteryplus.com sells them if you have one local, expensive though. Radioshack should sell them. However, you can check with Amazon in their search area using "2.4v 500mAh NI-MH". Make sure you check the reviews on them.
