BT400 Intelligent Diagnostic System | The Ultimate Solution for Battery Health
The BT400 simplifies the complexity of modern vehicle electronics. It features a high-contrast 1.7-inch TFT color display that provides real-time data on battery health, cranking power, and charging efficiency. Whether you are performing a routine check or a complex electrical audit, the BT400 provides the clinical data needed to ensure a vehicle's power system is reliable.
Advanced Diagnostic & Maintenance Suite
Safe Battery Replacement: Features a dedicated ECU Memory Saver mode. This allows you to replace a battery without losing the vehicle's clock settings, radio presets, or critical engine adaptation data.
Professional Battery Analysis: Supports a massive 20–2000 CCA range across all major global standards (CCA, JIS, GB, SAE, MCA, CA, DIN, IEC, EN, BCI). This is the definitive answer for anyone wondering how to test a car battery with laboratory-grade precision.
Leakage Detection & Waveform Recording: Monitor parasitic draws from 15mA to 5A. The BT400 can record up to 30 minutes of waveforms and data, allowing you to catch intermittent electrical drains that occur while the vehicle is "asleep."
OBD II PIN OUT Voltage Display: Instantly verify the voltage status of individual pins on the OBD II diagnostic port to identify communication errors or power delivery issues.
Startup & Charging System Tests: Analyze the health of the starter motor during ignition and the alternator’s output under various loads to prevent unexpected breakdowns.
Hardware & Industrial Reliability
Compact & Portable: Measuring just 134mm and weighing only 0.236 kg, the BT400 is designed for high-speed diagnostics in the shop or on the road.
High-Resolution Color Interface: The 128×160 resolution screen ensures that graphs and numerical data are clear and legible in all workshop lighting conditions.
Rugged ABS Construction: Built with a durable shell to withstand the impact, grease, and vibration of a professional automotive environment.
Future-Proof Updates: Supports software upgrades via a dedicated USB port, ensuring the device stays current with evolving battery technologies and vehicle systems.
