I MIGHT add, maybe 20 years ago I brought home 2 intact 300-C doors.
Bonus Electric windows, so I had a full spare setup.

After spending an hour or 3 cleaning them up I grabbed my handy
'off to the junk yard' 12v test battery.  Turns out even fully charged
it was too Weak to crank the window motors. According to the service
manual those motors take between 13 and 15 amps to run normally.
