Replace the battery. Even a tiny drain can cause a bad battery to do very strange things.
IF your alternator is charging properly you have a very serious drain to take the battery to 8 volts.
A battery this old should be replaced without hesitation.
Batteries are not purhchased/bought. We merely rent them for a time. They can fail from the shelf or last far beyond what we should expect.
Since your battery has been run down so low many times it is crippled in any case.
Fighting customer resistance to "buy a new battery" over forty plus years diagnosing things, even though I never sold any car batteries, was like pulling teeth without novicane.
With a fire chief with a two month old vehicle kept coming back saying the radios were running his battery down and his "mechanic" said it was the radios running the battery down in just two hours I just gave up. Went to the parts store and bought a new battery for his new vehicle. Gave the vehicle back to him and asked him to see if it solved his issue. Sure enough, problem solved. I did not tell him how it was resolved until he reported back.
My point is, unless you have the equipment to tell me how much current is being drawn I can only use my vast experience to suggest what is the most common problem.
