1.Instant Answers for Every Lead-Acid Battery

Flooded, AGM, Gel, EFB, VRLA, 12V or 24V—the BT200 handles them all. By measuring voltage and cold cranking amps (CCA), it checks State of Health (SOH) and State of Charge (SOC) and tells you the real story behind your battery. You can read the in-depth results on the screen, while three LED lights—GOOD, CHARGE, or BAD—give you a fast, at-a-glance status report. No more wondering, just clear answers.

 

2.Put Starting Power to the Test

Engines demand the most from a battery at startup. The BT200’s cranking test (12V and 24V systems) measures voltage drop and crank time under load and shows the results, clear as day. You can see if your battery is delivering dependable power or showing signs of quitting early, so you’re never stuck.

 

3.Tackle Charging Issues Faster

Is it really your battery, or is your charging system just not doing its job? Let the BT200 make the call. Its charging test checks the system’s health by analyzing loaded and unloaded voltage, helping you pinpoint alternator, regulator, and connections issues. That means you spot problems before they snowball into breakdowns.

 

4.Fast, Straightforward Operation

Hook it up and go. Just clamp onto the terminals, and the BT200 is ready to run tests on 12V and 24V systems right away. The rugged, compact design is built for the garage or the glovebox, and it’s simple (and safe) enough for anyone to use—no training required.

 

5.A Screen You Can Actually See

Forget squinting at dull displays. The BT200’s bright, large 2.4-inch color LCD makes results crystal clear, even in harsh sun or low light. Whether you’re testing in the garage, shop, or roadside, you'll see every detail quickly and accurately.
