How old is my Ac Delco battery with the code 2g31f54? I have been searching all over the Internet trying to decifer this? Why is it so hard to get this information?

  • Welcome to Motor Vehicle Maintenance & Repair! That doesn't look like a date code for ACDelco. You might be looking at the wrong code. It should (as the website says) "The warranty date code is located on the top label of the battery. The first character is either a P or S. The next two digits determine the month, the third digit is year and the fourth digit indicates the manufacturing plant." – Pᴀᴜʟsᴛᴇʀ2 Oct 10 at 23:23
