OK, I should have said "A flat bad battery will charge quicker than a
flat good battery" precisely because you need to put fewer amp hours
into the bad battery before it is fully charged.

What fills quicker from the same tap, a large cup or a shot glass?

I have heard many folks say something like "that battery must be good
because it takes a good charge in no time at all."
