Review on 🔋 Roadi 3-in-1 Auto Battery Tester: Upgraded Version with Accurate Testing for 12V Vehicles, Comprehensive User Manual, and Protective Case by Cristofer Cejudo

PROS: Easy to use Easy to read Long wires Protective edge coating that prevents breakage if you drop it CONS: Battery – FAST CHECK not usable-. Almost every battery I've tested said REPLACE, even freshly charged ones and one year old ones. Information is sometimes WRONG. Check the battery several times and there can be big differences in the results. Stupid Results: A battery just removed from the charger shows -98% charged! While VOLTAGE reads at 13.17! - How can a 12V battery be charged to 98% at 13.17V? I find that a tester can be very useful IF you take the RESULTS and INTERPRET them using common sense and not - REPLACE THE BATTERY - take it as absolute.
