## Description

FOXWELL BT705 Car Battery Tester 12V 24V, Automotive 100-2000CCA Battery Load Tester Analyzer, Digital Cold Cranking Charging System Alternator Tester for Heavy Duty Truck Boat Marine SUV ATV

## Features

- Pro-level All in One Car Battery Tester - The FOXWELL BT705 is backed by 14+ years of automotive expertise and a dedicated support team. It delivers professional analysis and comprehensive readings for 12V & 24V batteries, assessing SOH, SOC, starter, and alternator systems. Compatible with flooded, AGM, spiral, and GEL batteries (100-2000 CCA), it ensures 99.9% accuracy with upgraded copper clamps, secure clip-on leads, and advanced conductance technology. Built with desertcart GRS-certified materials (Global Recycled Standard), it qualifies as Climate Pledge Friendly—delivering pro-level performance while letting you make a greener choice.
- Professional-Grade Yet User-Friendly - Ideal for battery manufacturers/dealers, 4S shops, specialized garages, skilled technicians/ mechanics, DIYers, car owners and heavy construction equipment and heavy duty truck trailer, the BT705 suits 24V vehicles like trucks and buses, as well as 12V vehicles like cars, motorcycles, boats, and mowers. 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. After cranking test, this battery tester auto-switches to charging system test, assessing alternator output voltage, rectifier diode function, and charging current to identify issues like no output, low output, high output, or excessive ripple.
- 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.
