2021 Toyota Highlander — battery dies after the car sits for a weekend — Florida owner

Battery passes a quick test and charging voltage looks normal, but after two or three days parked the car sometimes will not crank. What is the cleanest parasitic-draw test on a modern car that takes time to go to sleep? I would rather test this logically than replace parts.
