Trusted Expertise - FOXWELL BT705 Battery Tester

Over 13 years of automotive expertise and dedicated service team. The FOXWELL BT705 battery tester is built for professional analysis of 12V and 24V batteries, including SOH, SOC, Starter, and Alternator systems. It covers 100-2000 CCA for flooded, AGM, spiral, and GEL batteries. With upgraded copper clamps and advanced conductance technology, it ensures 99.9% accuracy.

Professional-Grade Yet User-Friendly

Ideal for battery dealers, 4S shops, mechanics, DIYers, and car owners, the BT705 is perfect for 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.

Check Battery Life Effectively

The FOXWELL battery tester efficiently assesses battery condition by measuring SOH (State of Health) and SOC (State of Charge). It provides critical information such as available power, CCA (Cold Cranking Amperes), cranking voltage, cranking time, alternator output, no-load voltage, and loaded voltage. This ensures early detection of issues and reduces unnecessary maintenance.

Avoid Roadside Breakdowns

Quickly test the car battery's cranking system with the easy-to-use CAR STARTER TESTER. Precise readings for cranking voltage and time help identify potential issues before you're stranded. Use the tester to ensure the battery is functioning correctly and avoid unexpected breakdowns. If the battery has normal SOH but won’t start, check the starter or car ignition system.

Keep Peak Performance

Efficiently diagnose charging system issues by checking the output voltage of the alternator, rectifier diode, and charging current. Detect possible alternator issues like no output, low output, high output, and excessive ripple. This ensures your work is on track and minimizes battery problems.

Easy to Read

Equipped with a backlit LCD display, the BT705 is intuitive to read in any lighting condition, making it accessible for non-technical users. Its 5.9ft cable offers maximum flexibility for skilled technicians, DIYers, enthusiasts, drivers, and specialized garages. No app is required, and it remembers the last rating for convenience. The tester comes in a protective carrying case.

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 instructions on the screen to perform the charging and cranking tests.
