6V & 12V Battery Analyser

The Jansicotek KW650 is a digital battery tester that measures cold cranking amps from 100 to 2000 CCA on 6V and 12V lead-acid batteries. It uses conductance technology to assess health, charge status and internal resistance in milliseconds. The unit works on batteries installed in the vehicle or on the bench and covers flooded, AGM flat-plate, AGM spiral and gel types. A patented one-click readiness key gives quick emissions readiness status on OBD II petrol and diesel vehicles.

Suited for DIY owners and mobile mechanics

This tool suits owners who want fast health percentages and clear Good, Recharge or Replace advice without removing the battery. It also fits technicians needing a portable analyser that updates via firmware for new vehicle coverage. Buyers who require integrated alternator ripple diagnostics or heavy-duty commercial vehicle testing beyond 2000 CCA should look at something else. The tester does not support high-voltage EV or hybrid battery packs.

100-2000 CCA range with 99.5% accuracy

The analyser comfortably handles passenger car, motorcycle, ATV, SUV, boat and lawn-mower batteries within the 100-2000 CCA window. Its STM-32 chip delivers results referenced to Midtronics standards at over 99.5% accuracy, giving reliable health and charge-state data in milliseconds. Testing stops at the 2000 CCA ceiling, so large commercial truck banks or industrial stationary batteries fall outside the supported range.
