WEIWEISTORE BT201 12V Car Battery Tester, 100-2000 CCA, Capacity, Charging & Cranking Analyzer for Truck, Boat, RV, Marine Vehicle, and More Vehicle Tool Kit

Our BT201 automotive battery tester captures complete battery health data in one scan: real-time voltage, internal resistance, cold start current, rated capacity, charge level (SoC) and health status (SoH). It intelligently computes cold start capability and battery aging degree, so you can clearly know battery wear and judge whether replacement is needed. Different from simple voltage testers, this battery analyzer delivers comprehensive numerical data instead of vague prompts, supporting both daily DIY car inspection and professional repair shop precise troubleshooting. This 12V battery load tester covers a 100 to 2000 CCA detection range, compatible with 4 mainstream battery types: regular flooded wet cell batteries, flat plate AGM batteries, spiral AGM batteries and maintenance-free gel batteries. Widely applicable to sedans, pickup trucks, motorcycles, ATVs, RVs, yachts and fishing boats. Whether you test compact car small batteries or heavy-duty marine deep-cycle batteries, this cold start current tester matches all your 12V vehicle battery diagnostic demands without extra adapters. Integrate 3 essential vehicle electrical test functions to finish full system check: Battery Test: Deep scan single battery overall health and aging level; Cranking Test: Detect starter cranking voltage to evaluate engine starting discharge performance, classify result as Good/Normal/Bad/Very Bad; Charging Test: Monitor loaded & unloaded alternator voltage plus ripple value to locate faulty alternator diodes and abnormal charging faults. One tool solves battery, starter and alternator common failure points, ideal for auto mechanics to speed up repair efficiency. Portable compact body only measures 5.06 × 2.85 × 0.87 inches with bare machine weight just7.97 oz , easy to slip into glove boxes, tool bags or jeans pockets for on-the-go testing.
