The battery in my MB was the original Bosch so 20 years old when I replaced it.
(for general reference Lion are one of the worst battery brands out there. Exide are OK but that's far too expensive. Bosch and Varta are generally the exact same product with different stickers on and are always good, and rarely all that expensive.
I personally use Samsung 50S and RS50. The RS50 or 50XG are the optimal choice in my opinion.
I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.
The Bosch has slightly lower Cold Cranking Amps at 330 vs the Yuasa at 360. Also Bosch has 4 yr warranty vs Yuasa 5yr.
I have used Bosch, Panasonic, and now Amaron in my 2013 WK2. Bosch lasted as much as my previous 2 Mopar lasted.
The mechanic I go to gives me Bosch and they last around 2 years if not more. But then they do die within a day when they do.
I went to a Škoda dealer to look at a car to buy. The car was a Rapid 1.4 SE DSG which was advertised at £8995. The car was stored remotely from the dealer, basically in a field. The battery was completely flat.
Looks like I'm getting a battery replacement. Very disappointed in Samsung this year.
A few hours later he came back with a new S4 018 Bosch battery (original one was Yuasa HSB056). He assured me it had the same specs, despite being a different brand (40Ah, 12V). He installed it, and then told me it was a “slightly different base size” from the old one.
