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 Nick Granner

My husband and I bought this product to see if the batteries in our two cars were okay. It was a very simple plug and play type (more like plug and read). All you have to do is set the CCA (Cold Cranking Amplifier) and it will do the rest for you. He was able to show us that the battery condition for one car was good, but it only needed to be charged and confirmed that the second car was in good condition. Instead of buying a new battery, we can now just charge it. And in the long term we have a battery tester for future cars and batteries. The processing quality is very good.
