How much does the battery weigh? That can also be a guide to capacity.
the "RC 175" is "reserve capacity 175 minutes.

A quick googling says " This is the number of minutes a fully charged battery at 80°F will discharge 25 amps until the battery drops below 10.5 volts. An amp hour (AH) is a rating usually found on deep cycle batteries."

So 175 minutes is very close to 3 hours, so that says 25*3= 75 amp hours.

Typical automobile starter battery ... your Sprinter has a 95 AH starter battery.
