Starting issues

Ok Mopar gurus. Yet another issue in the saga of the 1974 Plymouth Duster… So, the car ran and then it didn’t. Put a new battery in it started and ran, but then would not start again. Though the battery might be drawing power from somewhere so we charged the battery and tried to start. Upon turning the ignition to start, heard something from the area of the starter, but no start. Thought he starter pooped out. Put a new starter in it and charged the battery again. This time it made the tell-tale dead battery clicking. I don’t understanding this because I had the charger on the battery for a few hours, and it was a new expensive battery 2 months ago. Any other ideas? Ignition?
