Abstract
An apparatus for determining life of a battery which supplies charged electricity to an electrical appliance is equipped with a storage part for storing relationship between standard total values of discharge voltage drop amounts since a start of discharge of the battery and standard life values, a discharge voltage drop amount totalizer part for totalizing the discharge voltage drop amounts since the start of discharge with the battery being discharged, and a life determination part for determining the life of the battery from a measured total value of totalized discharge voltage drop amounts and the standard total values of the storage means.
