6 V 12 V Battery and System Analyser

The Jansicotek KW650 tests 6 V and 12 V lead-acid batteries from 100 to 2000 CCA, covering regular flooded, AGM flat-plate, AGM spiral and gel types. It reads voltage, internal resistance, cold cranking amps, health percentage and charge state in milliseconds using conductance technology. The handset also checks cranking and charging systems on OBD II petrol and diesel vehicles.

Suits DIY owners and workshops needing fast

Technicians who want instant good, recharge or replace guidance will benefit from the 99.5 % accuracy and on-screen advice. The tester works with the battery in or out of the vehicle and includes a one-click readiness key for emissions checks. Buyers who require a built-in printer or wireless data logging should consider other tools.

Conductance testing up to 2000 CCA decides fit

The single figure that determines whether this analyser matches the job is the 100 to 2000 CCA test range. If the batteries you service fall inside that window the KW650 will deliver a result; if they exceed it you need a higher-rated unit.
