2012 E350 wagon
Bought a Die Hard AMG battery from advance auto a little over 2 years ago. About a year later the battery died. They replaced it due to a bad cell. Now it's happened again. The clerk says there's something wrong with the car and it's killing the battery. Had to call AAA for a jump. They saw no issue with the charging system. Could I just have bad luck and got 2 bad batteries?
Any suggestions before I send it to the shop.

Have you been driving less during Covid? Wouldn't hurt to make sure all the connections are clean and tight. Check for any parastic drains.
