Cost effective battery/starter/alternator tester
The tool indicated my battery CCA and starting voltage were low which was confirmed by my mechanic when I took my car in to have the battery replaced per the recommendation of this tool. The tests were listed in the order they should be performed on the screen of the tool. Screen prompts were clear and easy to follow. The results are summarized with clear recommendations such as "GOOD BATTERY" "GOOD-RECHARGE", "REPLACE", "BAD CELL-REPLACE", and "CHARGE-RETEST". It tells you the internal resistance of your battery, the state of charge as a percentage of full charge, the calculated available current in accordance with 10 standards including CCA, battery life as a function of available current compared to nameplate available current, the minimum voltage when starting the vehicle, the time it takes to start, the health of your alternator based on ripple voltage and charging voltage, and if you have a bad cell (no load voltage lower than expected). The tool works with various battery types including flooded, AGM flat pate or spiral, and gel.
