12V Battery Analyser with 1.8" Colour Screen

The LUOM KW208 is a 12V automotive battery tester that measures cold cranking amps from 100 to 2000 CCA. It evaluates battery health, cranking performance and charging system output on a 1.8 inch colour display. The unit weighs 0.46 pounds and measures 5.98 by 3.39 by 1.77 inches. It suits owners of cars, boats, motorcycles and trucks who want a handheld diagnostic tool.

Suited for 12V lead-acid batteries only

This tester covers regular flooded, AGM flat plate, AGM spiral and gel batteries rated between 100 and 2000 CCA under SAE, EN, DIN, IEC, BCI, CA, MCA and JIS standards. It does not support 6V, 24V or high-voltage EV packs. Buyers needing lithium-specific algorithms or voltages above 16V DC should look elsewhere. The operating temperature range is 0°C to 50°C.

TPU case and lifetime firmware updates

A protective TPU case is included to shield the device from drops and workshop fluids. The analyser records test data for later replay and offers lifetime free firmware updates via the manufacturer.
