The BT100 PRO uses conductance-based testing to deliver near-labor precision without complex setup. Lightweight and self-powered, it fits in a glove box and gives clear results on a bright 2.4\" backlit LCD so car owners, mechanics, and roadside responders can make confident decisions about battery health before a trip or during routine maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the BT100 PRO measure battery condition?\u003c\/h3\u003e\n\u003cp\u003eThe device uses advanced conductance technology to analyze a battery’s ability to deliver current under load, then calculates state-of-health (SOH), state-of-charge (SOC), cold cranking amps (CCA), voltage, and internal resistance. These combined metrics provide a practical picture of a 12V battery’s real-world performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConductance testing for accurate CCA and internal resistance readings\u003c\/li\u003e\n  \u003cli\u003eDisplays SOH and SOC to gauge remaining service life and charge level\u003c\/li\u003e\n  \u003cli\u003eSupports flooded, AGM, EFB, and GEL 12V batteries\u003c\/li\u003e\n  \u003cli\u003eOutputs straightforward statuses: GOOD, RECHARGE, REPLACE, BAD CELL\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the BT100 PRO easy and safe to use for non-experts?\u003c\/h3\u003e\n\u003cp\u003eYes — the BT100 PRO is designed for simple, safe operation.
