12v Battery Age?

I picked up a 2015 Prius V the past summer with 130k km (80k miles) which had all service done at a Toyota Dealer. I decided to check on the 12v battery to figure out the age and if I should replace it now that winter has rolled in. I believe the original 12v battery is in the car, 311014 is the code if I'm not mistaken. There is also a 2434 stamp on the casing which could be a 2024 battery?

Car has had no issues starting or exhibiting any weird electrical issues/inconsistent codes. I do fully intend on replacing the battery if the date code is indeed 2014.
