Here is a link to one: https://www.amazon.com/Battery-Rechargeable-Capacity-Flashli...

If it were possible to get 9800 mah out of an 18650 we might all be flying around with electric jetpacks. About the best capacity possible today is 3600 mah. This has been going on for years: https://www.youtube.com/watch?v=gGF9DZcBric

Fake or misleading battery products are so common on Amazon there is an ongoing class action suit: https://www.classaction.org/news/amazon.com-hit-with-class-a...

batteries are one of those classes of products (as mentioned elsewhere) where it's 100% impossible to buy anything legitimate on Amazon. Even if what I ordered was an OEM laptop battery (for example) what you would receive is, at best, a knockoff with OEM stickers applied.

It's fraud and Amazon is profiting from it. No amount of rationalization fixes that. If batteries can't be sold without endemic fraud then stop selling batteries. Otherwise you're a fraudster and deserve whatever penalties are appropriate.

The truth is that it is possible to police the suppliers, resellers etc. to prevent this, and Amazon has both the power and resources to do it. Amazon just doesn't give a damn.
