Slightly 2 years old battery

3 Jan 2020 •
I have a 2012 S63 AMG (MB) I have a slow start with this battery and it's a little over 2 years old. Can someone please tell me how to find out if I have a warrantee on this. I had a professional battery tester placed on it and he showed me where it was stable with the charge, then shortly after that, it started leaking out some of the charge. It's a real Mercedes battery, because of all the tags that are on it. No warning lights ever came on,  I noticed this problem about a month ago, from Dec to Jan 2020.              Thanks!

For how long it was on, how many RPMs it did, how many km/ph it drove? Is all the info possible to be retrieved using Xentry? The software that all the Merc dealers use around the world. If it's not possible, please tell.
