2026 TOPDON BT100 Car Battery Tester 12V Load Tester Charging System Analyzer

About this item

The TOPDON BT100 is a compact 12V battery and charging system analyzer that checks CCA, voltage, health and cranking power right at the battery terminals. It covers 100-2000 CCA batteries — flooded, AGM, Gel and EFB — and gives clear pass/fail results through color LEDs and a simple menu screen. No need to pull the battery out of the vehicle; just clamp on with the protected copper leads and test.

• Tests 12V lead-acid batteries from 100-2000 CCA (AGM, Gel, Flooded, EFB)
• Reads SOH, SOC, voltage, internal resistance and CCA value in seconds
• Runs 3 checks: battery health, cranking/start power, and charging system output
• Color LED result display: green (good), orange (warning), red (issue)
• Copper clamps with reverse-polarity and spark protection, no need to remove battery
• Works on cars, trucks, motorcycles, ATVs, boats and more; includes clamps and manual
