My S550 has two batteries - starter batter under hood and accessories battery in the trunk.

In 2009 MB S550 eliminated trunk battery. Following years there is one large 12v starter battery under hood against passenger firewall. There is another small auxiliary 12v battery under driver side dash which assists in electronic gear shifting and transmission operation. MB sophisticated electronics require healthy batteries, alternator, sensors, fuses and SAM (single acquisition module). They all must be working properly and SAM must be programmed to vehicle. This will allow functionality buttons to work prevent premature battery draw. You would think MB would have these related problems solved. They do not.
