Designed for convenience and accuracy, it reports State of Health (SOH), State of Charge (SOC), voltage, current and CCA compatibility across flooded, AGM, EFB and gel batteries. Its passive safety design powers on only when clamps are correctly attached, and a simple LED\/menu interface delivers results you can act on quickly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the BT100 check battery health?\u003c\/h3\u003e\n\u003cp\u003eThe BT100 runs a controlled load that evaluates how the battery performs under stress to determine SOH and SOC. Results identify whether the battery can hold sufficient charge or if its internal condition has degraded.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasures voltage and current to compute State of Health and State of Charge\u003c\/li\u003e\n  \u003cli\u003eSupports 100–2000 CCA battery ratings for common 12V battery types\u003c\/li\u003e\n  \u003cli\u003eUses a passive power-on that activates only when clamps are properly connected\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan it test starting and charging systems?\u003c\/h3\u003e\n\u003cp\u003eYes — the BT100 performs a cranking test to verify the battery can supply the peak current needed to start the engine, and it includes checks for alternator output and rectifier diodes.
