Help me restart my beetle

Hey folks I got a 1972 superbeetle that I’m trying to restart clean up so I can put it for sale. I got two little kids so I haven’t been able to drive it for about 4 months. When I try to restart it today I noticed I don’t get any spark to start. The oil light was dimly lit. Could it be as simple as the battery needing to be recharged? It’s about 1 1/2 year old. Or do I need to to go mess with the points, etc
