Review on 🚗 12V Car Battery Tester - TOPDON BT600, Cranking and Charging Tests, Alternator Load Testers, 100-2000CCA Digital Battery Voltage Tester, 3.5" Screen with Built-in Printer by Jon Booth

I am so glad I chose this battery tester. It's very easy to use. The color display is easy to read. The printer is a game changer, I can print out all the tests and use them for diagnostic and billing clients. The information he gives about the price is wonderful. I needed one that would show me battery status and measure battery charge when testing before charging. The operational test and charge test work great and provide excellent information including the mV ripple charge test. The start test shows start voltage and start time. I really like that it also gives the internal resistance of the battery. Very happy with this tester.
