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.
 
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.

Yea, I’ve read that. They changed it in 2021. Your comment is the first time I’m reading that it doesn’t work anymore at all tho. Internet is still full of ways how it should work. Thanks anyways.
 
You best choice would be using Apple' official service coverage tool. It doesn't matter if there is Apple Care or not. Last year, I used the tool to find the manufactoring date of an old trash can MacPro I bought from eBay.

It only gives you purchase date, not manufacturing date.

Right. Since the history is from Apple, it's like the first hand purchase (except for refurbished). That should give you a rough estimation on the manufactoring date. It's more accurate for BTO orders.

Yes, it really depends on a number of factors, such as how quickly the retailer is moving stock.

I bought a M4 MBA from Apple Store in August and the last charge date was April. I've seen units 8-10 months old before.
 
Tried that already, doesn’t work.
