12V Battery Analyzer for Vehicles

The BT100 Pro tests 12-volt lead-acid, AGM and GEL batteries across cars, motorcycles, trucks, boats and SUVs. It measures cranking performance from 100 to 1100 CCA and reports health, charge state and bad cells in milliseconds. A backlit LCD and large buttons make the pocket-sized unit simple to operate in any light.

Suits owners who want quick diagnostics

Drivers needing a fast health check before a trip or after winter storage will appreciate the instant readout and reverse-polarity protection. It is not for workshops that require printable reports, data logging or support for high-voltage EV packs beyond the 12 V range.

Handles 100-1100 CCA range comfortably

The tester covers the vast majority of starter batteries found in passenger vehicles and light marine craft. Accuracy is rated at 99.9 percent thanks to the onboard smart chip. Batteries rated above 1100 CCA or non-lead chemistries fall outside its measurement window.
