1. An apparatus for estimating a battery life, the apparatus comprising:

  • a battery monitor configured to monitor an output signal from a battery;

    a steady state detector configured to detect a first steady state in which the output signal stays in a steady state and a second steady state differing from the first steady state; and

    an estimator configured to estimate a battery life from a variation of the output signal in a transient state in which the output signal transitions from the first steady state to the second steady state.
