6V and 12V Battery Tester

The Jansicotek KW650 is a handheld automotive tester for 6V and 12V lead-acid batteries. It suits DIY owners, mobile mechanics and workshops that need fast health checks on cars, SUVs, light trucks, boats or lawn mowers. The unit tests batteries both in and out of the vehicle and delivers a clear Good, Recharge or Replace verdict.

100–2000 CCA Test Range

The single specification that decides fit is the 100 to 2000 cold cranking amp range. It covers regular flooded, AGM flat plate, AGM spiral and gel chemistries. Batteries rated below 100 CCA or above 2000 CCA fall outside the calibrated window and cannot be tested accurately with this tool.

Health Percentage and Charge Status

The tester reports voltage, internal resistance, cold cranking amps, battery health percentage and charge state in milliseconds. It comfortably handles routine starting-system diagnostics and alternator checks on typical passenger vehicles. It runs out when a battery exceeds the 2000 CCA ceiling or when a non-lead chemistry such as lithium is encountered.

Questions about this item

What does the 100-2000 CCA range mean when I test a battery in my car?

The tester measures cold cranking amps from 100 to 2000 CCA, covering 6V and 12V flooded, AGM flat plate, AGM spiral and gel batteries in cars, SUVs, light trucks, boats and mowers.

How does the OBD II interface limit what I can diagnose?

It works on all OBD II petrol and diesel vehicles for readiness checks and emissions data, but the battery and alternator tests run through the clamps, not the OBD port.

Will the 5.94 x 3.22 x 2.2 inch case fit in my glovebox or tool bag?

At 5.94 by 3.22 by 2.2 inches the unit is compact enough for a glovebox or small tool bag, and the package includes the tester, a manual and the three-year service note.
