Review on 🔋 ANCEL BST500 12V/24V Automotive Battery Load Tester, Car Cranking and Charging System Analyzer Scan Tool with Printer for Heavy Duty Trucks, Cars, Motorcycles, and More (Black/Red) by Sammie Prince

Too often you walk into the dealership and they tell you you need a new battery and you just feel like they are trying to sell you a higher price. Every car dealership should have this, just hook it up, no magic, no confusion, quick test and done, diagnostic check printed and a happy customer. I don't understand why not everyone uses it! I tested it on an old battery that was only 7.3 volts and still worked. It gives you a percentage of battery life so you can plan for the next battery or consider changing before winter comes and you're stuck with your car in the snow. That's great ! I've checked all my batteries around the house and at a few neighbors, it's like magic :D
