On a Mercedes-Benz the additional battery or auxiliary battery controls the operation of the automatic stop/start, but it is the main battery that turns the car on, so if the main battery is bad, the car will not turn it self off automatically. The car will tell you on the dash when it needs a replacement of the additional/auxiliary battery.
On newer Mercedes and BMW vehicles it is necessary to register your battery. You will need a scan tool to do this. If you have one is very simple. It is also a good idea to get one if you do not have one. The battery has to be registered because the computer knows the age and condition of the battery. As the battery gets older it needs to be charged differently than a new battery. The alternator will cook the battery by aggressively charging it.

Strap 23 Nm = 17 ft lbs

With ignition off, store the key fob away from the car. At least 7 ft away or 2m
When taking the vent tube off be careful, as the battery vapors emitted will damage surrounding components. It's a good practice to cover it and rout it correctly
Always check for damage on cable or terminals
Negative is usually black and positive is usually red or check on the battery + or - signs
Never let your tool touch any metal while removing the terminals, could cause spark, damage and/or may even get the tool welded to the terminals, specially if you touch both terminals with the tool
Tuck your terminals out of the way so they don’t bounce back and get in contact with the terminals again
Always start with the negative terminal first
Cover the positive cable so it doesn’t touch any metals
If your battery has vents make sure they go back on the battery
Always seat the terminals all the way down. Don’t pound the terminals on, because it can cause internal damage
Always pay attention to torch specs. Some terminals are very fragile
Check on the fabrication dates when you buy it. Month and year. No later than a month built.
