Review on 🚗 AUTDER 12V Digital Car Battery Tester - Voltmeter & Alternator Charging System Analyzer | Test Battery Condition & Alternator Charging | LCD Display & LED Indication | 13.5" Lead Length by Daryl Barton

I recently had to replace a battery which put me in a dilemma. weak. I have one now and will review it more carefully in the future. This is the ultimate in simplicity, I mean, before you start the car, plug it into the cigarette lighter, it shows the voltage, start the car, it shows the voltage and status of your alternator (NOTE: the toggle switch must be in the middle/unmarked position to use the alternator function that's all it will tell you straight away if your battery or alternator has a problem so for EASY USE + PERFORMANCE + VALUE it gives 5 stars all day.
