An 18650 with no A or B refers to an older and less capacity battery. An 18650b refers to the newer and higher capacity battery, 3400 mah.

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

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

Any 18650 battery will do. The higher the mAh you buy the in these the longer the light will run between charges. I'd stick with name brand 18650's BTW - Panasonic, Samsung, etc. The low cost/low quality 18650 are certainly cheap but they can be dangerous.

Electrically yes, physically NO. Both are 3.7V li-ion, both are 65mm long. The 18650 has a diameter of 18mm, the 26650 has a diameter of 26mm.

I agree with Paul Moll, I bought the 18650 Batteries thru amazon and they are better than the AAA batteries. Idk how this worked but, when I used the AAA batteries I only had one mode, but when I used the 18650 battery all modes were accessable.

No. 18650 batteries are physically larger than 14500 batteries. The 18650's won't fit in the charger.

Milliohm hours deals with longevity, and depending on the flashlight it won't affect brightness. Most flashlights won't allow the brightest levels when battery starts to get low. Also the quality of the batteries and charger had an impact. My boss had a crappy 3600 mAh battery that lasted half as long as my 2600mAh Tenergy, both 18650 style. I would say that the 18650's are a better option than two 123's, but some flashlights won't take the slightly larger 18650's.

it's hard to say most use 18650 batteries but without the model of your flashlight it's hard to say. look here for your model and it will tell you what battery it uses.http://www.lightmalls.com/uniquefire-flashlights

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

18650 Batteries come in two versions, one "unprotected" and the other "protected". The "protected" batteries are just a tiny bit longer than the other. That might make the difference for you.

Yes, they are different rechargeable batteries. Look online for BRC 18650 3.7V Li-ion. You will need 2 for the flashlight plus two or more for spares.

Yes, you can replace these batteries. The unit contains one lithium battery of the 18650 form factor. The OEM battery has 1300 maH capacity with tabs for solder connections. If you have some basic electronics skills, you can replace it with a battery of higher capacity. No need to buy a new unit, just replace the battery!

Model number 18650 / 2 600 Ah Li - ion rechargeable battery. Best to go to a batteries plus to ensure proper fit.

No. The 26650 is a somewhat larger battery and will not always fit every device a 18650 does.
