Abstract
A battery type identifying device is capable of identifying the type of a vehicle-mounted lead storage battery. The battery type identifying device includes: a charge processing unit which, on the condition that the state of a lead storage battery has reached a prescribed state as a result of a reduction in the amount of electricity stored therein from a fully charged state, carries out a determination charging process of charging the lead storage battery for a prescribed time; an accepted amount acquiring unit which acquires an amount accepted by the lead storage battery in the period during which the determination charging process is being carried out; and a determining unit which determines whether the lead storage battery is a liquid-type lead storage battery on the basis of the accepted amount acquired by the accepted amount acquiring unit.
