Customer Question

Was told I should buy the battery under the hood, which you called a starter battery, from a dealer. Dealer cost is over $200 and dealer said i probably should not disconnect that battery because it might mess up the computer settings. Is that correct and can i get that battery at Advance auto for example? Can I simply take that battery out and replace it myself and is there any special trick to that I would not know about?

Hello the dealer should not have told you that lol. The fact that it is a starter battery tells you that it's only function is to start the car. Your main systems battery is in the trunk. However I would advise that you get a gel or AGM battery from interstate. Or from Mercedes. The batteries from parts stores never last. They are easy to replace just make sure you take the negative off first and reinstall it last. Hope this information helps. If you have any questions please let me know. I'll do my best to help.
