According to this website, for a lead-acid starter battery, the difference between full voltage and empty voltage is 12.65-11.89=0.76V

If your battery loses 0.02V per day, assuming its all linear for simplicity, that means your battery would fully drain in 0.76/0.02 = 38 days
If your battery capacity is 95Ah, that is equivalent to a constant current of 95/(38*24)=0.1A
That sounds pretty good to me. My last S8 had a parasitic drain of 0.4A, my current S8 has roughly 0.15A
