18650 used to be the gold standard, Panasonic 18650 cells.
18=diameter, as in 18mm 65=length, also in mm 0 means it's round 21700 that Elon has proposed and what replaced the 18650 cell in Tesla has become the new standard. I won't buy a flashlight that doesn't take the new 21mm cell. capacity increased from about 3500 mAh to 5000mAh |

I had never heard of an 18650 battery until I had to make a new battery pack for the GF's shiatsu back massager thing, Then I had some left over so I bought a headlamp that uses 18650s. I'm impressed with it, it recharges with a Micro USB plug like my old cellphone chargers have.
My dad harvests them from old laptop batteries and makes them into "button tops" so he can use them in his headlamp. If one of the 18650s goes in a laptop battery the whole battery is pretty much shit and won't hold a charge long, but there's plenty of good ones in there that still hold a charge. |

I have flashlights that use many different batteries
Aaa Aa Cr123 18650protecred 18650 unprotected 21700 And a few proprietary cells In my opinion the jump from 18650 to 21700 is an easy one to make for a handheld light On a rifle light it gets harder to justify as yes you do get extended run time, but you add weight were you least want it, near the muzzle. My favorite light is a noctigon kr1, yes it made in China and takes 2weeks to get to you, but damn if it isn't the best pocket thrower I've ever bought. 1500lumen and 99k candela In such a small form factor is amazing. It definitely isnt typical made In China junk. Machining wise it make surefire look like crap. And at $40 with a tritium vial on the button I just love it For me the 18650 size is ideal |

3mm difference in length won't make a difference in most flashlights because of the spring, but the 5mm increase in width will mean many of them will not be compatible with the new batteries.

In my opinion the thickness difference between 18650 and 21700 is minimal.
Having lights that are pretty much identical but using the two separate cells Olight warrior x 18650 Olight warrior x pro 21700 They are the same thickness externally The added 5mm length is noticeable though as the light doesn't slip as fare down into the pocket. Now I'm sure I'm a minority as I like lights that have a larger head to throw light a good distance. I absolutely hate a flood light if its not some magnetic work light or a task light like a headlamp |

I'm a big 21700 fan.
The fact that you can run your old 18650's and CR123's in most new 21700 size lights with an adapter just makes the transition too easy. My daily carry is a Fenix PD36R that, while bigger than my old Surefire E2D, offers so much more performance and run time the extra size is barely a consideration. I'm hoping Modlite will offer an OKW weaponlight with a 21700 battery someday soon. |

I have several 18650s but also like my little inexpensive 14500 lights. I have a bunch of them, all over the place. They're compact and very bright. These are very good bang for your buck IMO if you get some decent batteries and a charger that works:

18650's are going to be around for a while. I picked up a Wowtac A6, 18650, and a Thrunite T2, 21700, a while back. Same format, side button only, but the T2 is noticeably larger. I've temporarily displaced the A6 so no comparison photos. That one's a keeper for sure, if I can find it.
21700's have replaced 26500's though. I have a TC20 with no plans to get rid of it but I'll probably grab another 2 batteries. Worst thing about 21700 batteries for me is I needed a new longer charger. Anyone here good at modding lights? I like my old Fenix PD20 with a 16650 in it but it stopped working a few years ago. I'd love a 2 level driver for it- loose head maybe 15 lumens, tight head maybe 300. |

Quick, terrible comparison picture.

I think most 21700 lights from the bigger names have it so far because those batteries are too long to fit into older chargers. |

Gotcha, I wasn't sure what you meant.
Affordable lithium lights I like @htown156 TN12- $40 sometimes less, you'll need an 18650 battery and charger, 'classic' tactical format, tail cap turns on/off, side button changes modes, I leave mine on medium usually (about 200 lumens), Wowtac A6- $30, charging port, one button only, light turns on in memory in low, medium or high, moonlight is long press from off, turbo is double click from any mode (very easy to learn), stock battery is ok, I put a 3500mah in it. Several different brands offer similar lights. Pretty much anything under $200(?) is going to be Chinese made, unfortunately. Here's the picture I wanted to do! Shit, I forgot the 26650 this time! Meh, those are dead now anyways. Olight S1 with 16340 (not really recommended for an only light, 16340's have lousy capacity), Wowtac A6 with 18650, Thrunite T2 with 21700 Almost identical formats and a good comparison.
