Battery life is going to be dictated by number of cycles,
not time. And, I would imagine there would be a 'black box'
recording battery use for warranty purposes. At least that's
what I'd do if I were selling them.

The current toy evidently 'cooked' a number of the onboard batteries
during its 'record breaking' Japan-Hawaii leg

My guess, based on my electric RC modelling experience, is that
they were recharging them a little hot. Batteries usually can be
discharged much faster than they can be recharged. But I admit
that I don't even know off hand which battery technology they
are using. I used lithium-polymers.
