Do I need a new battery?

What is your question?

My car wouldn’t start and everything would flash and it clicked. I was able to start it with a jump and it needed a jump for a few days to start and the check engine light came on but after a few days of running the engine for around 15 mins for a few days it will now start just fine and the check engine light is off. Does this mean I need a new battery?

What makes this problem better or worse?

Running engine makes it better
