About this item

• FIRST THINGS FIRST: Cranking and Charging Tests are available only on APP. Both IOS users and Android Users need to download "Batterylab" App to get access to these two features. This tester CANNOT test lithium battery, nor 6V/24V batteries.
• BUDGET-FRIENDLY: Below $20, the TOPDON BT20 is a great value for a car battery tester. With four testing modes (battery load, voltage test, two app-exclusive modes: cranking, and charging), this tester works on 12V lead-acid batteries. Note that the latter two test modes require an app.
• EXPANDED TESTING ABILITIES WITH APP: The BT20 pairs with your device via Bluetooth to access additional cranking and charging tests. The app displays real-time voltage waveform graphs with data playback functionality. Note that Bluetooth is to be connected via the app, not phone settings.additional cranking, charging, and voltage testing capabilities. Easily view real-time voltage waveform graphs with data playback functionality. NOTE: Bluetooth is to be connected via APP, not phone setting.
• FAST & ACCURATE RESULTS: Get battery life displayed in Low/Medium/High within 1 second by clicking the TEST button. The testing accuracy can reach 99.5%, thanks to the latest conductivity technology. The BT20 is ideal for users who want quick and reliable results. Note that Bluetooth is to be connected via the app, not phone settings.
• UNIVERSAL COMPATIBILITY & MULTI-LANGUAGE SUPPORT: Ready to use with 12V lead-acid batteries found in a variety of vehicles, including boats, motorcycles, ships, and trucks. With 8 different language options, it's easy to use this device anywhere in the world.
• IDEAL FOR CAR OWNERS: The BT20 has safety features such as reverse polarity and "no spark" protection and long clamp leads for testing from inside or outside the vehicle. It's a perfect battery analyzer and load tester for small repair shops and car owners alike. Makes a great gift for car enthusiasts.

Product Description

BT20 BATTERY LOAD TESTER

The BT20 is TOPDON's entry-level wireless 12V battery tester. Offering load, voltage, charging, and cranking tests, the BT20 offers high-precision voltage detection and real-time voltage monitoring.

This easy-to-use device lets users of all skill-levels view voltage waveform graphs and test reports through an app. Test reports can be generated automatically, and easily share and save test reports. Data Playback function query battery voltage history data, help users analyze the problem by playing back charge and discharge data reports.

Its load test method provides accurate results, making the BT20 a battery tester with superb cost-effectiveness.

Quick access to test results in the app by linking your phone via Bluetooth.

Run Charging Tests: Test a battery's charging performance with the app and analyze the results.

Run Cranking Tests: Test the battery through the load of the car itself, and view the results in the app.

Voltage Test:

Further analyze the battery's health through its voltage, and predict the battery's power status with the results of the BT20. Three kinds of indicator lights communicate the battery level, full, medium, and low.

Load Test:

Built-in load modules help determine the status of the battery.

Multi-Dimensional Display of Battery Status

No-load and load voltage readings can be displayed in the APP, and there is a real-time voltage waveform graph for accurate monitoring.

Battery Load Test The BT20 applies load tests and monitors the voltage response of the battery. Users gain a clearer look at the actual remaining battery capacity.	Battery Voltage Test Once the clamps are connected to the terminals, the BT20 delivers the battery voltage results in the blink of an eye.	Cranking Test The cranking test measures the battery's cranking voltage and cranking time when starting up. Normally, the cranking voltage should be above 9.6V. As for the cranking time, The shorter, the better!

 

Charging Test The charging test measures the no-load voltage and load voltage, which helps you to understand the battery charging status, and alternator performance.	Supports 8 Languages to Maximize Utility English, German, French, Italian, Spanish, Portuguese, Russian, Japanese	A Wide Range of Tests with Highly Accurate Results The BT20 is designed for versatility. With a variety of testing capabilities, analysis tools, and a battery range of 5 to 20 volts, the tool delivers highly accurate result.
