Description

【12V & 24V Dual‑System Compatibility】One tool for all your vehicles—the GOOLOO ST5 battery tester delivers true 12V/24V compatibility at a price that beats most 12V‑only testers. It covers everything from cars, SUVs, and trucks to RVs, boats, and heavy‑duty vehicles. With a 100–2000 CCA range and support for Flooded, AGM, GEL, and EFB batteries, this one tool handles every lead‑acid battery.

【Complete 3-in-1 System Diagnosis】Get more than just voltage readings with three diagnostic modes— ① Battery Test (12V only) checks SOH, SOC, voltage, CCA, and internal resistance to evaluate battery condition. ② Cranking Test (12V/24V) analyzes starter power and voltage drop to ensure the engine starts smoothly. ③ Charging Test (12V/24V) checks the charging system status to avoid overcharging or undercharging. In seconds, you'll know your battery completely—no need to drive miles to the repair shop. The Pro's Secret — Now in Your Garage.

【Safe & Easy Operation】No sparks, no heat, no risk—even if you connect the clamps backwards. The ST5 features built‑in reverse polarity protection that keeps you and your battery completely safe. Equipped with a large 128x64 LCD screen and an intuitive menu-driven interface—no complex setup or manuals required. Its portable size (7.40 x 4.06 x 1.42 inches), paired with the included carrying case, makes it easy to store in your glove box, center console, or tool bag, so you always have professional diagnostics on hand.

【Worldwide Compatibility】The ST5 supports 10 major battery standards—CCA, CA, BCI, MCA, DIN, IEC, EN, SAE, JIS, and GB—making it compatible with virtually every lead‑acid battery from any manufacturer across North America, Europe, Asia, and beyond. Whether you're testing a Japanese JIS battery, a European DIN type, or a North American SAE unit, the ST5 delivers accurate results every time. Test any battery from any manufacturer, anywhere.

【Crystal Clear 2.4" Color Display】The bright 2.4‑inch color screen delivers crisp, clear results in any lighting, from dim garages to direct sunlight, with green/red color indicators that make readings instantly understandable: green for good, red for replace. Professional-grade diagnostics have never been this clear and easy.
