In the 2012 Mercedes CLS550, the extra battery is situated in the trunk. It plays a vital role in supplying power to the "stop-start" feature and running your car's accessories. If your car is starting smoothly but you're consistently seeing a red warning symbol on your instrument panel indicating a battery issue, you might need to swap out the 12-volt auxiliary battery. You have the option of going for the official Mercedes-Benz auxiliary battery or selecting a more budget-friendly alternative that fits the requirements.
