Toolit Automotive Battery Tester Battery Voltage and State of Charge Meter DBT 300

Electronic multifunction battery tester for 12V starter batteries with LCD display. The DBT 300 measures the battery voltage and the state of charge (result in %) as well as the starting voltage of the starter and the output voltage of the alternator. The dynamic resistance measurement minimizes battery discharge and provides an unaltered result that is not affected by surface charge, the energy consumption of devices (various LEDs, etc.), or faulty connections (oxidation of terminals/cable lugs, loose terminals). The DBT 300 features reverse polarity protection and a corrosion-resistant, shockproof housing. No batteries are required: it operates using the power from the vehicle battery.
