About This

KNOW YOUR BATTERY HEALTH – The AUTOPHIX BAS100 battery tester quickly evaluates your battery’s condition by measuring its State of Health (SOH) and State of Charge (SOC), giving you clear insight into battery aging and remaining capacity. It also performs a cranking test to verify if the battery has enough power to start the engine, and a charging test to ensure the charging system is working properly. Identify issues early to avoid costly mistakes — and save up to $300 by preventing unnecessary battery replacements.
99.98% ACCURATE DIAGNOSIS – This car battery tester features high-conductivity copper alligator clips with strong springs and an anti-slip coating for a secure, stable connection — no loose contact, no fluctuating readings. Its built-in AI smart chip delivers precise battery condition data in seconds with 99.98% accuracy, ensuring fast, safe, and reliable results every time. Note: Please select the correct battery type, standard, CCA, and AH values, and confirm the temperature (above/below 0°C) before testing.
WIDE MULTI-BATTERY COVERAGE – The battery load tester accurately tests 12V and 24V batteries (100–2000 CCA), including flooded, AGM flat plate, AGM spiral, GEL, and EFB types. It supports major international standards such as CCA, BCI, CA, MCA, JIS, DIN, and SAE, ensuring broad compatibility across cars, SUVs, pickup trucks, vans, RVs, motorcycles, boats, jet skis, lawn mowers, ATVs, UTVs, snowmobiles, heavy-duty trucks, tractors, buses, and construction or agricultural equipment. Perfect for both personal and professional use. Note: Not compatible with 6V/8V batteries or lithium batteries.
SAFETY & RELIABILITY YOU CAN TRUST – Built with a durable industrial-grade ABS shell, the alternator tester offers excellent physical protection and electrical insulation. Its 4-in-1 smart protection system automatically detects and prevents reverse connections, short circuits, over-voltage, and over-current to keep your battery, vehicle, and you safe. With temperature protection built in, it delivers stable, accurate results in both freezing cold and scorching heat.
EASY TO USE – CONNECT AND GO – Just connect the positive and negative battery terminals, and the auto battery tester instantly starts testing — whether the battery is installed or removed, even if it’s completely dead.
