Abstract
An electronic battery tester for testing a storage battery includes first and second Kelvin connections configured to couple to the battery. A forcing function applies a time varying signal to the battery through the first and second Kelvin connections. Further, a resistive load is configured to couple across the first and second terminals of the battery and draw a relatively large current. The storage battery is tested as a function of a dynamic parameter measured through the first and second Kelvin connections and as a function of a response of the storage battery to the relatively large current drawn through the resistive load.
