Toolit accutester DBT 350

The TOOL IT DBT350 battery tester is a professional diagnostic tool for comprehensive battery analysis in various vehicle systems. This precision instrument measures battery voltages from 8 V to 30 V and assesses battery condition using advanced dynamic resistance measurement technology. The device automatically compensates for fluctuations in ambient temperature to ensure accurate readings, unaffected by surface charge, parasitic loads, or poor connection points. It is compatible with three types of lead-acid batteries ranging from 7 Ah to 230 Ah capacity, including sealed VRLA, GEL, AGM FLAT, AGM SPIRAL, SLI, standard flooded, and START/STOP batteries (EFB/AGM). The DBT350 performs multiple testing functions: 12 V battery tests for voltage and state of charge assessment, 12 V and 24 V starter tests for cranking voltage evaluation, as well as 12 V and 24 V alternator tests for no-load voltage, charging voltage, and ripple current analysis. Instant analysis capabilities include measuring available cranking power and a percentage battery health display. Practical design elements include insulated clamps for safe operation and a large 4-digit display for clear visibility of test results. The dynamic resistance measurement method minimizes battery discharge during testing and provides reliable results, unaffected by common interference factors. This professional diagnostic tool serves automotive technicians and enthusiasts who require precise battery and electrical system evaluations across various vehicle types and battery technologies.
