Battery Maintenance or not
Here are pictures of my 2008 Sprinter battery located under the drivers feet. I have never seen this type battery before. I see where it appears to be phillips screwdriver heads and the plastic cover...

Load test to 400 amps. Interstate Distributors* have genuine load testers. Other places have toys.
Place 400 ampere load for full 15-seconds. Does voltage drop to less than 9.6 volts? If yes, regardless if the battery was made last week it is weak and it's your decision.
*"Do you have a variable load carbon pile battery load tester?"
I would be very tempted to replace with AGM* because VARTA batteries are insanely over-priced and Delco may or may not have your group size. Resist replacement with a conventional battery. You do not need to breathe sulfuric acid and lead vitamin supplements - neither does your family.
Bosch charging systems use notoriously low voltage set-points which are perfect for AGM. The question is "Can you find the correct BCI group size?"
