So we should have chargingTime = 0 when there is no battery. In addition, we wouldn't be able to know if the device has a battery or not.

The spec bugs are now fixed as per your proposal. Please check that we're now aligned with the implementation and ready to publish.

... and special thanks for the most excellent feedback :)
