Just replaced the 12v battery on my coupe with another OE battery. Old original battery had a date code of 11/13 stamped on the bottom of the case and 1/14 engraved into the negative terminal. The new battery had a date code of 11/19 on the underside and 3/20 on the negative terminal. What's the significance of the different dates - curious?

SWAG - battery case was built November 2019 and the plates/acid and such were installed and rolled off the assembly line March 2020, pretty fresh!

Thanks. Yeah, that was kind of my guess too. Just wanted to the input of others.

What I also found interesting is that the battery manufacturer is not shown anywhere on the battery that I could find. It used to be that even after the star was added to a part that the manufacturer left his ID somewhere on the part. Varta used to be the main provider of batteries for Mercedes.
