Is it possible: New battery is more than 10 years old?

I bought a replacement battery and the instructions are really excellent. I was happy, that everything started. But now I get displayed, that the battery is manufactured in January 2011 — more than 10 years ago! That is new? Really? I am really concerned and asking myself, what to do. Is there a reasonable explanation for that?

As requested I show the Screenshot of CoconutBattery:

Before this I installed Battery Health 3:

Interesting, their manufacturing date differs slightly. At the beginning I had an old version of Battery Health 2 installed, which showed me the same day in January but in year 2011. How comes, that different apps show different dates? I expect Battery Health 2 having a bug, but the two apps shown in the screen shots differ a couple of days. Strange.

Best Regards,

Dirk

I bought a battery from iFixIt back in early 2021. When I fitted it that also showed manufactured in January 2011 and I was using Coconut Battery. When I asked IFixit about the problem they told me to disconnect my computer from the power supply and let the battery run right out before plugging it in again. when I did this the date changed to January 2021. However, the battery has now been in service a little over 12 months and this morning the Design Capacity is down to 47% and in the red, which means the battery needs changing again. The cycle count is 53. According to the internet the battery should last between 800 and 1000 cycles. I won't be buying any more batteries from iFixIt.

It is possible (although unlikely) that the battery was manufactured in 2011. However, it is more likely that the battery is newer and something is wrong with the date. Are you seeing the 2011 manufacture date on the battery itself, or somewhere in MacOS? If 2011 is printed on the battery it might be possible that something was misprinted. If you are concerned about the battery’s age, you could contact the manufacturer.

Thanks for your answer. There seems to be no date printed on the battery. I see the manufacturing date using the app "Battery Health 2" of Fiplab. Is there another possibility to view the manufacturing date by software? The MacOS Systeminformation report shows "ifixit" as manufacturer, but no manufacturing date. I bought the battery a couple of days ago. I cannot imagine, it has been stored for 10 years.

Thanks for your time and hints. I just installed a different app and it showed me a manufacturing date of Jan 2021 -- 5 months old. That sounds reasonable. Sadly, apple does not show the date themself in their software, thus a 3rd party software seems to be necessary.
