  Was gonna say maybe they’re 18650s but it Def says AA on them. I’m gonna go with it’s a made up / AI-generated image

    They would have to be 21700 cells to hold 4.3AH. 18650 cells top out around 3.6AH. While it is possible to make higher capacity cells, there are some major downsides with doing so.

  It’s just a stock photo used since at least 2017 that appears to have had the 4300mah text added on more recently.

  Looks like AI to me. Also, those would most likely be NiMH batteries, which AFAIK don't have any lithium.

    The way its packaged with the indent at the top would make it a lithium cell but yeah its fake anyways

  Maybe they’re just ultra fire batteries?

    One time I went to a local shop with cheap electronics etc, and they sold… UItraFire batteries, with an i instead of an l! Double fake 😄

  In case anyone’s curious: it is likely a cell wrapper misprint/typo.

  4300mWh AA lithium ion cells are a standard extended-life chemistry. 2866 mAh is their actual rated capacity.

  There are plenty of cells that size over 3000mah.

    The highest capacity one that is properly commercially available is the vapcell f15 which is known for quality control issues. Its advertised capacity is 1500mah but multiple sources measured it at an actual usable capacity of 1250-1350.

      14500s are fairly uncommon… I assumed these were the much more common 18650.

  It’s probably an AI gen image.
