And I was, as Arfa understood, merely referring to the fact it ran fast
with new batteries.

Would you blame the car for failing when you replace the 12 V car
battery by a 24 V car battery? An Accutron watch doesn't run fast if you
replace a used 1.35 V mercury oxide battery by a new 1.35 V mercury
oxide battery. So, the running fast problem has nothing to do with using
a _new_ battery; you just have to use the right (new) battery.
