hello everyone,

i've keep coming across conflicting information as to if there is a auxiliary battery in the car (also known as a secondary battery). I have already replaced my main battery underneath the hood, but is that the only battery in my vehicle? I have my mechanic coming to replace the starter + alternator, so if there an auxiliary battery i figure i buy it as well just to have everything replaced at once. Does anyone know if the 2007 C280 luxury trim 4matic has a auxiliary battery? the vin to my car is WDBRF92H17F935465
