I must admit that my battery check consists of leaving the start/stop function on until it becomes active and then switching it off. If that didn’t happen then I’d be asking the dealer to take a look at the battery. It hasn’t happened yet on my 21 plate W177 but it did on my previous W176 and when they checked they replaced it under warranty no questions asked.
