Automotive Battery Tester & Circuit Leakage Detector

Automotive Battery Tester & Circuit Leakage Detector

Keep your vehicle running reliably with this professional-grade Car Battery Tester & Circuit Leakage Detector. Designed for home garages, roadside diagnostics, and workshop use, this compact ABS tool reads live current and voltage simultaneously — helping you locate battery drains, faulty circuits, and leakage issues fast, without ever removing your battery cables.

Key Features

• On-Vehicle Diagnosis: Perform self-diagnosis and leakage module localization directly on your vehicle. Captures live current and displays real-time readings so you can identify faulty circuits quickly at home or in the shop.
• Dual Readout Display: Shows simultaneous voltage and current readings in one view, making it easy to monitor intermittent current draw and gather accurate repair insights before any trip.
• Leak Locating & Fuse Removal: Pinpoint circuit leaks by integrating routine leak checks and fuse removal localization — all without disconnecting battery cables. The built-in self-diagnosis function makes it easy and convenient to use.
• Universal Vehicle Compatibility: Works with trailers, trucks, sedans, and most standard 12V vehicles. Supports spec comparison identification, precise dark current diagnosis, circuit localization, and milliamp-range detection.
• Trip-Ready Assurance: Provides preventive fault detection through battery health assessment and cranking static voltage display, plus a charge depletion warning — so you can trust your vehicle to start every single time.
