Review on 🔋 ANCEL BA301 6V 12V Car Battery Load Tester Alternator Analyzer | Automotive Battery Tester for Motorcycle, Car, Boat, Light Truck and More by Johnny Grant

I didn't like that I received an email from the company saying if I was having trouble downloading a software update before I even got the unit in the mail have. Such an action would make me distrust the device. However, I must stress that the email said: if the device fails to install the update, do not install it now before using it. So. I didn't install the software update because my device still hasn't failed. As with everything else, if I don't attach the device clamps to a reliable battery and properly, it won't read properly. I tested the device on a known defective battery and received accurate data on the defective battery. Same results with good batteries. It was right. Using a voltmeter on the failed batteries confirmed this device was accurate so I'll tell you this device works great for me. Time will tell the whole story, but so far this device is fine. Buy it to check battery health. You can trust it.
