Idk where they got the picture from but 4300mah in aa size would be insane. Thats like 2.5 times as much capacity as how much the best ones provide currently.
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
Yeah probably tho i kinda wish they existed lol
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?
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.
Edit: 2866 x 1.5 = 4,300
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.
