Abstract
An apparatus contains an inertial body held by three electrical conductors along the three principal inertial axes, wherein a voltage is applied to each of the three electrical conductors and are configured such that when a predetermined acceleration threshold value for the inertial body is reached the conductivity of at least one electrical conductor is impaired such that the reaching of a predetermined threshold value is detectable by the voltage measuring device. A rechargeable battery having an apparatus for detecting a critical fall and a method involving detecting three voltages are also provided.
