Abstract
An electronic battery testing device includes first and second electrical probes for coupling to first and second battery terminals, respectively, and electrical circuitry coupled to the electrical probes for providing an output related to battery condition. The probes each have a pair of electrical connections. A bridge circuit connected between the first and second electrical probes provides a bridge output. An amplifier connected to the bridge output provides an amplified output. The amplified output is indicative of a loose connection between an electrical probe and a battery terminal. The amplified output may be used to indicate an alarm condition.
