About this item

The TOPDON BT100 is a compact tester for 12V car, truck, marine, and motorcycle batteries rated 100–2000 CCA. It checks battery health, starting (cranking) performance, and the charging system, then shows clear results — SOH, SOC, voltage, and current — on a backlit screen with easy LED indicators for good, weak, or needs-recharge. No need to remove the battery from the vehicle, and it works across a wide temperature range with multi-language support.

• Tests all 12V batteries from 100 to 2000 CCA — flooded, AGM (flat or spiral), gel, and lead-acid types.
• Runs full battery health, cranking, and charging system checks in just seconds.
• Backlit LCD shows SOH, SOC, voltage, current and rating, with simple 3-LED good/bad/recharge indicators.
• Works both in-vehicle and out, no need to pull the battery out to test it.
• Meets IEC/DIN (100–1400) and EN (100–2000) standards, and can read voltage as low as 4V.
• Built to handle -20°C to 65°C operating temps, with menus in English, Russian, Spanish, French, Italian, and German.
