Review on 🔋 eOUTIL 12V Car Battery Tester - Auto Battery Load Analyzer with LCD Display for Testing Battery Life Percentage, Voltage, Resistance, and CCA Value (AE310-1) by Carlito Tardy

This thing beeps when connected to the battery. I got 12.76 volts with the car parked in the driveway overnight and I measured it in the morning. Mind you, I measured the 500 CCA battery that Honda replaced as my previous 410 CCA battery was going to die after just 2 years of use. This thing measured about 476 CCAs after several tests to confirm my readings. The battery was replaced in February 2020 and is 16 months old at the time of writing. I think the battery was just dead and just needed to be charged as my lights on the dash were flashing to the beat of the starter.
