I recently bought a 2024 M3 MacBook Air 15,12. It has a ten digit serial number (instead of 12 or 11) and Coconut Battery says "Manufacture date: unknown". I have tried Coconut and several online checkers but they can't handle my serial no.
Got a tip for us?

Apple changed to random serial numbers a while ago. The public can no longer decode the date.
The only time the manufacture date is available is before the first charge. The battery will show a "last charged" date, which is the date of assembly.
