My Shop’s Go-To Battery Tester for Every Vehicle

It’s affordable, fast, and accurate—way better than the pricey tester we used to rent. I’ve recommended it to every fellow mechanic I know, and they all swear by it now.

Feature-Packed but Could Be Sturdier

I love the functionality of the BT500—it tests voltage, cranking amps, and generator performance flawlessly, and the 12-language support is a huge plus for my mobile mechanic business with diverse clients. It handles all battery types (VRLA, GEL, AGM) with accurate readings, and the color screen makes results easy to explain to customers.

They Work Great for All My Vehicle Batteries

I’ve recommended the BT500 to so many friends in the auto industry, and we all love it. Super easy to use—just plug it in, and the 2.8-inch color screen clearly shows battery health, even for AGM or EFB types. Not expensive at all, especially for how many battery types and standards it covers.

Accurate, Easy to Use, and a Must-Have for Any Vehicle Owner

I couldn't be happier with the VDIAGTOOL BT500 Battery Tester, it is hands down one of the most useful tools I have added to my garage. From the moment I connected it, the device delivered fast and accurate readings on battery health, voltage, internal resistance, and cold cranking amps. I have already used it on my car, motorcycle, and even an ATV, and it handled each test flawlessly. What I really appreciate is how simple it is to use, the color screen is clear and easy to read, and the results are displayed in a way that makes sense even if you are not a professional mechanic. It goes beyond just battery testing too, the ability to check the alternator and starter system has already helped me identify a small charging issue before it became a big problem. The build feels solid with strong clamps, and the safety protections such as reverse polarity, over voltage, and anti spark give me peace of mind. Shipping was quick, and the customer service team was friendly and responsive to my questions. For the price, this tool delivers professional grade performance right at home. Absolutely a 5 star purchase and I highly recommend it to anyone who wants confidence in their vehicles battery and charging system.
