Abstract: The invention relates to a method for identifying a battery type (Pb, Li ion) by means of a battery testing device (1), having the steps: application of a DC pulse having a current strength (IB) of at least 30. Ampere to a battery (18) to be tested for at least five seconds; before the application of the pulse, measurement of a pre-pulse voltage (U0) of the battery; during the application of the pulse, measurement of a pulse voltage (U1) of the battery; determination of a transition voltage difference between the pre-pulse voltage and the pulse voltage; determination of a characteristic of a transition voltage difference parameter in dependence upon the transition voltage difference; assignment of a specific battery type (Pb, Li ion) to the tested battery in dependence upon the characteristic; and a battery testing device and a battery testing system.
