Battery keeps dying

2013 with the original battery. My kids left the interior light on and battery died. I jumped it but now keeps needing to be jumped. I tried to drive around for 30/40 mins and I was able to park, turn the car off, turn it back on a few mins later, head to my kids sports, then home with no issues but two days later it was dead again.

I’m considering replacing the battery. Wife thinks a battery charger is not needed bc it’s an older battery and it’s just time to replace it. Opinions on this rock auto battery.
