Overview

Diagnose your car and check its battery with one easy-to-use tool. The leagend BA570 combines an OBD2 scanner and 6V/12V automotive battery tester to help you find common engine, electrical, and starting problems without relying on guesswork. From checking the Check Engine Light to testing battery health, live vehicle data, starting and charging systems, leagend BA570 gives you practical diagnostic information right in your hands.

Whether you're a DIY car owner, preparing to buy a used vehicle, or simply want a reliable diagnostic tool in your garage, leagend BA570 makes everyday vehicle troubleshooting faster, easier, and more convenient.

Key Features

One Tool for Two Essential Vehicle Checks

  • Why buy separate tools for your car's electronic systems and battery?
  • leagend BA570 combines an OBD2 scanner and automotive battery tester in one compact diagnostic tool.
  • Use it to check what's happening inside your vehicle, understand warning lights, evaluate battery condition, and investigate starting or charging problems—all without switching between different devices.

OBD2 Scanner for Everyday Vehicle Diagnostics

  • When your Check Engine Light comes on, you don't have to guess what it means.
  • leagend BA570 can:
  • Read and clear Diagnostic Trouble Codes (DTCs)
  • Check and clear the Check Engine Light (MIL) after appropriate repairs
  • Display live vehicle data from up to 249 ECU parameters
  • View freeze-frame data
  • Check I/M readiness status for emissions-related inspection preparation
  • Read vehicle information including VIN, IDs, and CVNs
  • Support engine and transmission system detection
  • Work with common OBD II/EOBD protocols
  • Get more information about what your vehicle is reporting before deciding what to do next.

Test Your Car Battery Before It Leaves You Stranded

  • A weak battery can cause slow cranking, starting problems, and unexpected electrical issues.
  • leagend BA570 tests 6V and 12V lead-acid starting batteries and provides key battery information, including:
  • CCA (Cold Cranking Amps)
  • Battery voltage
  • Internal resistance
  • State of Charge (SoC)
  • State of Health (SoH)
  • It supports common battery types including Regular Flooded, AGM, GEL, and EFB, helping you check the condition of your battery before replacing it unnecessarily.

Check Starting & Charging Systems

  • Battery voltage is only part of the story.
  • leagend BA570 can also test 12V/24V vehicle starting and charging systems, helping you investigate whether a starting problem may be related to the battery, starter, or charging system.
  • This makes it easier to narrow down the source of common vehicle starting and electrical problems.

One-Key Quick Test for Faster Diagnostics

  • Need a quick overview?
  • leagend BA570's One-Key Quick Test brings together essential vehicle checks for more efficient troubleshooting. You can quickly perform battery testing, starting-system and charging-system checks, voltage monitoring, and OBD II diagnosis from one device.
  • It's especially useful when you want a fast health check before a long trip, after your vehicle has been sitting for an extended period, or when you notice unusual starting behavior.

See Vehicle Data in Real Time

  • leagend BA570 doesn't just give you a fault code—it helps you see what your vehicle is doing.
  • The dynamic data stream supports up to 249 ECU operating parameters, allowing you to monitor available vehicle information in real time.
  • The real-time voltage curve can also be recorded for up to 120 seconds and played back later, giving you a clearer picture of voltage behavior during testing.

Keep Your Diagnostic History

  • leagend BA570 can store up to 1,750 historical test records, including:
  • Battery test results
  • Starting-system tests
  • Charging-system tests
  • Voltage curves
  • Engine diagnostic reports
  • Keep your previous results for reference and compare information when troubleshooting recurring problems or monitoring vehicle condition over time.

Built-In LED Lights for Convenient Testing

  • The built-in LED lights make it easier to work around the vehicle and identify the testing status, especially when checking the battery or connecting to the OBD II port in less-than-ideal lighting conditions.

Designed for Everyday Drivers

  • leagend BA570 is designed to make vehicle diagnostics more accessible—not just for professional technicians.
  • Its 2.4-inch TFT color screen, straightforward functions, compact design, and wide range of diagnostic capabilities make it a practical tool to keep in your garage, toolbox, or vehicle.
