1. A method for charging a battery wherein the charging of the battery voltage is terminated when the battery is fully charged and the voltage of the battery begins to decrease, comprising the steps of:

  • step 1, a voltage decrease -Δ

    V of a battery;

    step 2, measuring 9 length of the time during which the voltage decrease is detected,step 3, integrating the detected voltage decrease -Δ

    V over the measured length of time of step 2,step 4, comparing the integrated detected voltage decrease of step 4 to a predetermined total value, andstep 5, terminating the charging of the battery when the integrated detected voltage decrease exceeds the predetermined total value.
