FOXWELL BT705 12V/24V Battery Tester 100–2000CCA 🔧
Description:
This professional Foxwell battery tester is built for mechanics and fleet operators who need quick, on-vehicle assessments of 12V and 24V batteries and charging systems. It combines load testing and alternator analysis to help identify weak batteries and charging faults, making it useful for heavy duty trucks, boats, and automotive workshops.
Key Points
The unit performs multiple battery tests including flooded, flat plate AGM, AGM, spiral gel, and regular lead-acid types. It reports battery condition using common ratings such as CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, and SAE, so results match manufacturer specifications. Tests can be run with the battery in place on the vehicle, which saves time and avoids battery removal. Consider that very corroded terminals may affect contact quality and test accuracy.
Technical Specifications
Name: FOXWELL BT705
- Voltage range: 12V and 24V operation
- Load test range: 100–2000 CCA according to the product listing
- Functions: battery load test, cranking test, charging system alternator analyzer
- Supported battery types: flooded, flat plate AGM, AGM, spiral gel, regular lead-acid
Usage Recommendations
Connect the clamps securely to clean battery terminals and follow the on-screen prompts to select battery type and rating before running a test. For best accuracy, avoid testing immediately after a long drive; allow the battery to rest for a short time so state-of-charge stabilizes. If the tester indicates a charging system fault, check belt condition and alternator output as the next diagnostic steps.
Advantages
This model offers clear, manufacturer-oriented results that help match diagnosis to accepted standards and ratings. Its support for both 12V and 24V systems makes it versatile for mixed fleets and marine use. The on-vehicle testing capability reduces downtime and simplifies routine checks for workshops and mobile technicians.
