Compact 12V Car Battery Tester, TOPDON BT20 for Car, Truck, SUV, Boat

The BT20 is TOPDON's entry-level wireless 12V battery tester, offering load, voltage, charging, and cranking tests with high-precision voltage detection and real-time voltage monitoring. This easy-to-use device allows users of all skill levels to view voltage waveform graphs and test reports through an app, with data playback functionality to help analyze charge and discharge data.

The BT20's load test method provides accurate results, making it a battery tester with superb cost-effectiveness. Users can quickly access test results in the app by linking their phone via Bluetooth. The app enables running charging tests to analyze a battery's charging performance, as well as cranking tests to view the results of testing the battery through the car's own load.

Further battery analysis is provided through voltage testing, which can predict the battery's power status. Three indicator lights communicate the battery level - low, medium, and full. The built-in load modules help determine the battery's status, and the no-load and load voltage readings can be displayed in the app along with a real-time voltage waveform graph for accurate monitoring.

The BT20 supports a wide range of tests with highly accurate results, designed for versatility with a battery range of 5 to 20 volts. It is compatible with flooded, AGM, gel, EFB, and VRLA battery types, and can perform cranking and charging tests in addition to load and voltage tests.

For convenience, the BT20 is equipped with safety features like reverse polarity and "no spark" protection, as well as long clamp leads for testing from inside or outside the vehicle. It is an ideal battery analyzer and load tester for small repair shops and car owners alike.

Note that Bluetooth connectivity is achieved through the app, not phone settings. The app, previously known as BT20, has been renamed to BatteryLab and is available on both iOS and Android. Users should search for "BatteryLab" on the respective app stores.

The BT20 is offered at a budget-friendly price below $20, making it a great value for a car battery tester. With its expanded testing capabilities through the app, fast and accurate results, universal compatibility, and multi-language support, the BT20 is a versatile tool for car owners and enthusiasts alike.
