@cengland0 NO! I have multiple flashlights that claim to use an 18650. They all require a sleeve to keep from rattling around. The 26650 fits those same flashlights without the sleeve.
@cengland0@yakkoTDI I have several flashlights, including my favorite EDC, that use the 18650, and it fits each without any problems (and without needing any sleeves).
@cengland0@yakkoTDI
Concur. Flashlights actually built for the 18650 need no sleeve. If they have one, they were probably built to use the triple-AAA holder, which is a kluge that is common enough that I found a secondary source for the sleeves alone. I’ve been looking for units that will take the 26650, but hadn’t found any so far; the ones built for the AAA adapter are generally 23mm ID, too small to accept a 26650. The real sneaky-trick-level conversion is using a single 14500 with a dummy pass-through adapter to power a flashlight that was built for two AA batteries, if the emitter has a voltage regulator that can handle the higher full-charge voltage.
@phendrick@yakkoTDI in the beginning, there was a problem if you bought a protected 18650 because they might be 2mm longer because of the extra pc board. All the flashlights I have today contain springs with enough throw to accommodate either a protected or non-protected battery.
@cengland0 After reading the above comments I came to the conclusion that the 26650’s wear muscle shirts and vests but the 18650’s wear coats and hoodies…Did i get that right?
@2many2no
So, not a dead or near-dead alkaline. I rehabbed a three-D MagLite that had a really bad case of corrosion-locked alkalines once. It took power tools and a special chisel to get them out.
@blaineg@cengland0 I wonder if the cheap inconsistent ones we see in the reviews nowadays are more likely to be the rectangular ones? The AAAA style 9V have been around for a long time I think and I never had any problems with them dying prematurely in smoke detectors back in the day, though they still liked to choose 2am to start chirping when they did.
@lljk Just this evening ran into a flashlight in my junk that takes 2 D’s. It’s even a waterproof one. Batteries are dead though and I don’t have any in the apt.
26550
@yakkoTDI Stupid typo. That should be 26650.
Whichever one fits in my TV remote.

@yakkoTDI seems like a problem with your flashlight and not the battery.

@sicc574 I don’t get the joke or reference you’re trying to make.
@cengland0 @sicc574 Muscle shirts and vests do not have sleeves.
@yakkoTDI okay, I get it now. Would never have figured that out alone.
@cengland0 @yakkoTDI
Me neither.
The one that fits where you want to put it.
@katbyter
@katbyter
Not always. It is unwise to put a 14500 where a AA belongs.
The one that doesn’t leak and destroy my flashlight.

I suspect the battery powering this puppy is of an objectively superior size.
@mehcuda67
I suspect this one has similar kit…

AAAA
@blaineg in case you were trying to make a joke, AAAA batteries really do exist. One of my laser pointers use that size.
@cengland0 Nope, no joke. I’ve got a few Streamlights that use them. I even have some spare AAAA’s on hand.
@blaineg @cengland0 You can also just take apart a 9v in an emergency and get 6 of them.

@blaineg @kuoh only some 9 volt batteries are like that. Others have stacked rectangular batteries. Like these:

I remember D batteries and shoving six or eight of them into a boombox. Kinda miss those.

AAAA
Or the good old 6 volt.
@blaineg I used to have a flashlight that took that 6 volt battery.
@cengland0 I had a fluorescent lantern that took two of them. I dropped it once, and it self destructed from the weight of the batteries.
