Genuine batteries

RipleyGenuine batteries

I got tired of getting 18650's that clearly didn't perform or last as well as they should, gotta be knockoffs.
So I hear that Battery Junction sells genuine stuff at a premium off course. I also was under the impression their reputation was sketchy at best.
This is the worst business I've ever dealt with. Endless delays with no communication, available listings for discontinued product (as I find out much, much later), snarky chat attitudes, a total disrespect for the customer.
Please help, where to get genuine batteries?

RogueJSKI get most of my rechargeable flashlight batteries like 18650s, 16650s, and 16340s through either Fenix or Illumn.
Fenix offers their own house brand of batteries:
https://www.fenixlighting.com/...s/batteries-chargersWhile Illumn is a small but reputable battery retailer who sells a bunch of different high quality smaller brands:
https://illumn.com/batteries.htmlI do have some Streamlight and Surefire rechargeable batteries, but these big name tactical flashlight brands' batteries generally cost a lot more for what is often worse specs than the smaller but well regarded battery brands like Fenix, Molicel, Sanyo/Panasonic, Vapcell, or Keepower.
If you really want to get into the weeds on battery quality and specs, the flashlight ultranerd sites like candlepowerforums.com or r/flashlight have a lot of deep dives and lively debates on battery brands and construction.

Good to know - I'll try illumn. I have single Vapcell that seems to be working well (got it w/ a flashlight that was gifted to me). I'd like Sanyo/Pana if I can get them in button top.

Perception Liion Wholesale Store DIY 500 Amp Store18650 Battery StoreAll three are reputable. Be careful with 18650 battery store, check the URL. There's also a copycat 18650battery.com that is NOT reputable.
edit to add- I see someone else recommended illumn. They have a good reputation as well.

"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."
