When the engine is cold, my battery seems to have enough juice to turn the car over and start it without issue.
When hot, it doesn't but jumpstarting from another car works first time so overheated starter (first suspect) not at fault.
When the engine is running, however, I don't seem to ever get more thank 13.7 volts across the terminals. However, my multimeter is a bit flaky
in the voltage area.
Q: Which is more likely to be the culprit? Alternator or Battery (Battery has been deep discharged a few times, so could be problematic)??

What ignition system ? it sounds like it gives too much static advanced to me.
13.7 should be more than enough volts.

13.7 Jolts is perfect.

Its not the battery to confirm just do a cranking voltage test,

Really just the voltage when cranking the engine but with no spark.
Should be about 10+ volts on a fully charged battery .
A voltage bellow 9 volts especially in a a cold start scenario indicates a dead or gassing cell.
Normally a battery with a dead cell shows about 6 volts under heavy load but may rise to 8 volts after a few seconds.
