Doesn’t matter. Either the battery is good and/or needs a charge, or it’s bad and/or can’t take/hold a charge. If you have proof of purchase date you may or may not have some warranty left. If no proof of purchase date you are SOL. So in my opinion the manufacturer date is moot for all practical purposes.

Looks like the factory battery. Open the driver’s door and check the assembly date, add 3 weeks.
