Starting and battery problems with BMW 3

I own a 2015 BMW 3 with 298000 km and am experiencing the following problems: the car won't start and the battery is weak when starting the engine. I have noticed that the battery could be damaged due to an accident and the engine cuts out, probably due to lack of voltage. Also, the minus terminal is damaged and I have suspicions that the IBS could be damaged. What would be the solution to fix these problems?

Start by replacing the damaged minus terminal and ensure all battery connections are clean and secure. After that, test the battery's voltage and health. If the battery is weak, consider replacing it. If the issue persists, inspect the Intelligent Battery Sensor (IBS) for any faults. Let me know how it goes or if you have further questions!
