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...

Take a look at your photo on the left side, near the top. See that clear vent hose? Stop and ask your self, what does it mean? Your existing battery is a non AGM battery.
Your battery is strong because you use it frequently enough to keep it nearly fully charged, and infrequently enough that it doesn't go through a lot of charge /discharge cycles. It also helps that your diesel probably starts up first time, every time, very, very quickly, due to low mileage on the motor. Nothing is easier on a battery than starting up once in the morning cold with glow plugs, and then going 200-300 miles before the next diesel refuel at the end of the day, then shutting down for the night, to repeat the process the next day. Only one major glow plug running discharge session and one cold start per 200 or 300 miles is easy, peasy life on a starting battery. Do that 2 to 4 times a year, between sitting there stored, fully charged, and it's an easy life.
