FOXWELL BT705 Car Battery Tester 24V 12V, Professional Alternator Tester, Automotive 100-2000CCA Load Tester, Digital Cranking Charging System Analyzer with High Accuracy for Trucks, RVs & Boats

  • Avoid Costly $200+ Misdiagnosis with Commercial-Grade Accuracy - Featured by Project Farm, the BT705 heavy duty battery tester uses advanced conductance technology to deliver precise SOH (Health), SOC (Charge), and CCA (Starting Power) readings for 12V & 24V batteries. Why it matters: It accurately pinpoints "hidden" battery degradation, preventing you from spending $200+ on unnecessary battery( AGM, EFB, Flooded, and GEL) replacements or alternator repairs. Clear "GOOD / REPLACE / CHARGE" prompts eliminate all guesswork.
  • Pinpoint Battery, Starter & Alternator Issues Before You Replace Parts - The BT705 goes beyond a basic battery check by helping you identify where the problem actually comes from. Its Battery Test evaluates overall battery condition, the Cranking Test helps reveal starting system weakness and voltage drop, and the Charging Test checks alternator output. Instead of replacing parts based on guesswork, you get clearer direction on whether to recharge, replace, or inspect the charging system further.
  • True 1-Person Operation with Extra-Long 5.9 ft Cable - Don't struggle with cheap testers that only have short 2-foot cords. The BT705 is equipped with a generous 5.9 ft (1.8m) extended diagnostic cable. You can comfortably sit in the driver's seat to turn the ignition while simultaneously reading the real-time cranking and charging data on the 2.8" enlarged screen. Complete a full system diagnostic entirely on your own—no second person needed.
  • Stable, Repeatable Results for Seasonal Checks and Daily Testing - Battery diagnosis is most useful when results stay consistent across retests. With its upgraded algorithm and advanced conductance technology, the BT705 is designed to deliver stable SOH, SOC, and CCA readings through changing temperatures and repeated checks. Whether you're testing before and after charging, comparing multiple vehicles, or monitoring an aging battery over time, it helps you track battery condition with greater consistency.
  • 12V & 24V Wider Compatibility - Ideal for multi-car households, aging vehicles, RVs, boats, pickup trucks, motorcycles, and seasonal equipment, the BT705 helps you manage more battery checks with one reliable diagnostic tool. Its support for both 12V and 24V systems, plus compatibility with Flooded, AGM flat plate, AGM spiral, GEL, and EFB batteries from 100-2000 CCA, makes it a smarter long-term investment for garages, driveways, and light fleet use.
  • Built on 17+ Years of FOXWELL Diagnostic Expertise - For over 17 years, FOXWELL has focused on automotive diagnostics trusted by drivers, serious DIYers, and technicians worldwide. The BT705 reflects that experience with a rugged drop-resistant housing, secure copper-plated clamps, intuitive menu design, and last-result memory for easier review. It’s built to feel like a dependable diagnostic tool in both busy shops and home garages.
