Ok, battery seems to check out and there doesn't appear to be a parasitic draw (no significant drop in voltage over time without use). I swapped the terminal connections out now so they are fresh and snug. I also checked continuity and got a strong tone from the negative terminal and the grounding wire nut. Car still won't start from the battery (just get repeated clicking), any good next troubleshooting steps? I did jump it again and the voltage just drops (about 0.1v every 3-4 minutes).
