The battery is almost certainly dead.
Something else wrong with your car likely killed the battery and if that's the case buying a new battery will just result in the same problem pretty soon.

That battery is absolutely cooked, sounds like the cells have sulfated to hell or there's internal damage from deep cycling
The fact that it's only taking 72-94Wh when it should be 600Wh is screaming dead cells, and that voltage drop from 12.8 to 4v in 2 hours is not normal even with parasitic draw
The battery is trash - if it was at 4v, the cells are either internally buckled/shorted - or the AGM is damaged and thus will not hold any charge (no capacity).
my dishwasher has around 200 mile motorway range on a 64kWh net battery, which'll get me from Oxford to Darlington on a single charge, I could get to Newcastle if I camp behind a truck for most of it. My car is also stupidly inefficient for an EV, better EVs like a ID.3 or Megane could go further with smaller batteries.
Paid charging is problematic mainly because the T8 charges so slow. You'd have to leave your car at a charger for like 5.5 hours to fill the battery.
I had to change the battery on my Volvo 940 7 years ago, it was the original battery from 1996 Wich means that my battery lasted for 22 Swedish winters.
My 3 years old XC60 battery has been diagnosed as bad 55% last 2 weeks ago, I said to them keep it as I feel they are still good and road worthy. Gonna do a snapshot again at another 6 months to evaluate.
My 2017 original battery stayed alive for 8 years and 148k miles fascinated me how long it lasted and the fact that the auxiliary battery is still fine
The factory battery in my 2007 S60R lasted just under 10 years, and I thought that was remarkable. Much more expensive than an auto store battery though but you get what you pay for I guess
I just replaced my 2012 Volvo XC 60 battery. The car has 155k miles and the battery lasted for over 13 yrs. I drive in cold weather for over 6months/yr.
