The only drawback we noticed was that software updates require a Windows system, which could be inconvenient for some users. Still, its reliability and ease of use make it a strong option for both home users and professionals.
Overview of the TOPDON Battery Tester BT600
We recently tested this compact battery analyzer and found it straightforward to use right out of the box. The 3.5-inch color screen displays clear readings, and the built-in printer makes it easy to keep a record of test results without connecting to another device.
The BT600 handles both 12V and 24V lead-acid batteries, which gave us flexibility when checking different vehicles. Its long cable let us stay in the driver’s seat during cranking tests, which saved time.
We liked the accuracy and the ability to update the software, though the Windows-only support limits some users. The build feels solid, but the printer paper runs out quickly if used often.
Pros: clear display, accurate results, convenient printer.
Cons: printer paper costs add up, software updates need Windows.
Key Features
We spent some time using the BT600 in our workshop and found that it combines accuracy with convenience. It feels built for everyday use, and a few design choices make it stand out from other testers we’ve tried.
Professional 12V & 24V Battery Testing
We appreciated how quickly the BT600 handled both 12V and 24V lead-acid batteries. It recognized different types—AGM, GEL, EFB, and standard flooded—without needing much setup.
