Legit flashlights use 18650s, as do most powerbanks

Damn these are no Samsung 30Qs but those are about 5x more expensive. Btw 13 batteries is the sweet spots as shipping jumps for 14 batteries (13 comes out to $26), if you need less be sure to look at quantities as shipping price jumps at certain points (6 batteries seems to be the next step down)

Just so people don't accidentally bought this thinking it is AA. I don't remember having any "toys" or appliances that uses 18650. buying them to maybe replace your tesla batteries when it failed? Big Grin
Tool Battery Packs use 18650s. So do many flashlights.
Battery packs for ebikes use them..laptop battery packs use them... power banks use them..

And the lists go on and on...

After the AA...and maybe AAA, 18650's may be the next most widely used battery today.
It is certainly up there with CR2032 and 9v...and probably more widely used than both.

Pardon my ignorance on the subject but, would these be the same as a your regular rechargeable AA or AAA batteries? If so would I be able to recharge them with my eneloop charger? TIA!!
These are different volts than AA. Your charger would not know how to charge them.
It really does not matter though because 18650's are larger than AA and it is highly doubtful that you would be able to fit them into an eneloop charger.

They're replaceable if you know how to solder or own a mini spot welder.. you can't just swap em out though no.

The exception would be the ones that use flat cells eg DeWalt power stack battery packs.

Don't most flashlights require protected cells with the tit? I use these in my vape though
dang, just noticed this since you pointed this out, so im going to pass. A friend also had a lightsaber that wouldn't work because he was trying to use batteries without the tit.

No, no, these are much more powerful than your AA or AAA batteries. If you're unsure about them it's likely you won't need them. These are what's in Tesla battery packs or cordless power tools, flashlights, vape mods, ect…

Hmmm 🤔 trustpilot reviews are 50 50 for this site. Was tempted, but not gonna do it
Do you but, I've personally ordered 4-5x from here no issues. BTW do you trust Amazon? They have a 1.7/5 star rating from Trust Pilot..
Sorry about that, best wishes to your ego 👍

Well, technically I think they'll work as long as they aren't too short without the tit, but there's a risk of overheating and explosion, as i understand it. IDK how big of a risk, but enough for me to use the protected ones
