Its easy-to-read display and advanced conductance testing deliver precise, reliable results for all users.
- Car Battery Doctor - The FOXWELL battery tester quickly assess overall battery condition with SOH (State of Health) and SOC (State of Charge) analysis. Identify issues early with detailed insights, including available power, CCA, cranking voltage, cranking time, alternator output, no-load voltage, and loaded voltage, helping to prevent unexpected failures and unnecessary maintenance.
- Cranking & Charging System Test - Even below 0°F, this cold cranking amps (CCA) tester can accurately test the cranking system by turning on the engine and measuring cranking voltage and time. This battery checker tester helps detect weak batteries before failure. If SOH is normal but the car won’t start, check the starter or ignition system.

- Ready to Use Anywhere – Equipped with a 2.8" digital LCD, the BT705 offers a larger and clearer display with than typical 2.4" screens, making results easier to read in any lighting condition—perfect for non-tech users. The 5.9ft test cable is almost twice as long as standard ones, allowing solo testing without needing a second person. No app or phone required—just plug and test. It also saves the last test result and includes a rubust carrying case for easy storage and transport.
- Important Notes - Ensure positive and negative clips have good contact for accurate results. When testing inside a vehicle, make sure all accessory loads are cut off, the key is on the OFF position and the doors are closed. Follow the instruction on the screen to do the charging test and cranking test.
