6 V and 12 V battery analyser

The Jansicotek KW650 tests 6 V and 12 V batteries from 100 to 2000 CCA including flooded, AGM flat plate, AGM spiral and gel types. It reads voltage, internal resistance, cold cranking amps, health percentage and charge status then advises whether to recharge or replace. The unit works on batteries inside or outside the vehicle and delivers results in milliseconds.

Check your battery type and CCA rating

Confirm the battery is a 6 V or 12 V lead-acid unit rated between 100 and 2000 CCA before testing. The analyser supports regular flooded, AGM flat plate, AGM spiral and gel chemistries; other chemistries are not covered. Ensure the terminals are clean and accessible for the supplied clamps.

Handheld tester with clamp leads

The device measures 5.94 x 3.22 x 2.2 inches and weighs little enough for one-hand use. Colour screen and a patented one-click readiness key make navigation straightforward. Clamp leads connect directly to battery posts for in-vehicle or bench testing and the unit includes a three-year after-sales service period.
