ANCEL BST100 12V Car Battery Tester for Cars, Motorcycles, SUVs, Boats

Product Information

About this item

• 【3-IN-1 Car Battery, Starter & Alternator Tester】The ANCEL BST100 car battery tester checks battery health, engine cranking performance, and alternator charging output to help identify whether slow starts, repeated battery drain, or charging concerns may come from the battery, starter, or charging system. A practical automotive battery tester for faster troubleshooting before replacing parts
• 【 Than Battery Voltage】This digital battery tester displays measured CCA, battery health, state of charge, voltage, internal resistance, and rated battery value in one clear result. Understand battery aging and starting capability instead of relying on voltage alone with this 12V automotive battery analyzer
• 【4-Wire Kelvin Testing for Consistent Readings】Separate current and voltage paths help reduce interference from cable and contact resistance for more stable battery test results. The conductance-based testing method evaluates compatible 12V batteries without applying the heavy current used by traditional carbon-pile battery load testers
• 【Check Cranking Voltage & Starting Performance】Use the battery cranking tester to measure cranking voltage, starting time, and test status while the engine starts. Detect weak discharge performance or low starting voltage before slow cranking develops into an unexpected no-start condition
• 【Alternator Charging & Ripple Test】The battery and alternator tester checks charging voltage with electrical loads on and off, along with alternator ripple output. Help identify insufficient charging, unstable output, excessive ripple, or possible alternator and charging-system problems
• 【12V Battery Tester, 100-2000 CCA】Test compatible Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, and EFB 12V lead-acid starting batteries installed in the vehicle or disconnected for independent inspection. Supports major standards including CCA, BCI, CA, MCA, JIS, IEC, EN, DIN, SAE, and GB
• 【Clear Results with Built-in Protection】The backlit LCD, simple controls, audible prompts, and multilingual menu guide users through battery, cranking, and charging tests. Review the latest test results, while reverse-polarity protection, over-voltage protection, and loose-lead detection help support safer and more reliable connections
