I didn't see the original posting, but IME deep discharging a car
battery, by allowing a current drain of 200mA for a couple of
weeks,
for example, kills them stone dead. No matter if they're new or
not.

Well, considering that in my trade cars can be sitting around some
weeks (whilst claimants, loss adjusters and anyone else do their
work) if you were correct we would be fitting many more new batteries
than we do...

The batteries on my Cosworth used to last until the first time we
went
on holiday and left the car to stand for a week or two, after which
the
battery would not hold a charge.

Hell, cars sit around dealers yards longer than that...
