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 Jeremy Sabey

I needed this. It's simple and very easy to use. First, it saved me a lot of money. The mechanic tried to tell me I had a "scattered leak" in the battery. That this computer system is draining my battery. It's going to cost me $700 because he has to remove the whole dashboard to get there and computers are very expensive. I bought this battery tester to check the voltage. 12.5 volts is normal. I'm going to sleep. When I woke up in the morning. I checked the battery but it's still 12.5. There is no drainage at all. He wanted to take me to the cleaners and this machine saved me. So, thank you.
