TOPDON BT600 Plus Battery & Resistance Tester 6V/12V/24V

TOPDON BT600 Plus battery tester

The TOPDON BT600 Plus is a professional 2-in-1 battery and internal resistance tester, and the only TOPDON model that directly tests 6V, 12V and 24V batteries. It runs battery, cranking, charging, full system and ripple tests on 12V and 24V vehicles, making it ideal for workshops, fleets, truck and 4WD specialists, and battery distributors.

Its built-in 5200mAh rechargeable battery sets it apart from standard testers. It can test deeply flat batteries down to 2V, which most testers can't even power on for, and you can review results away from the vehicle. It tests Flooded, AGM, Gel, EFB and VRLA batteries from 100 to 2000 CCA, and measures internal resistance on lithium, alkaline and carbon-zinc batteries. Sequence testing lets you check up to 500 batteries per group, and the built-in thermal printer produces instant reports for customers. A 3.5" colour screen, storage for your last 10 results and updatable software round out the most capable battery tester in the TOPDON range.
