LUOM KW650 6V 12V 100-2000 CCA Battery Tester

6V/12V Battery Analyser

The LUOM KW650 tests 6V and 12V lead-acid batteries from 100 to 2000 CCA, covering flooded, AGM flat plate, AGM spiral and gel types. It suits professional technicians and DIY owners who need fast health, charge and cranking diagnostics on cars, boats, motorcycles and lawn equipment. The digital display shows voltage, internal resistance, cold cranking amps, health percentage and a clear Good, Recharge or Replace verdict. A patented one-click readiness key speeds emissions checks on all OBD II petrol and diesel vehicles.

Verify battery voltage and CCA range

Confirm the battery is a 6V or 12V unit rated between 100 and 2000 CCA; the tester does not support other voltages or capacities. Ensure the posts or terminals are accessible for the supplied clamps, whether the battery remains in the vehicle or is removed. The unit runs on AAA cells, so have spares ready. No external power supply or computer connection is required for basic testing.

Handheld tester for workshop or roadside

The compact 5.94 x 3.22 x 2.2 inch analyser fits in a glove box or tool bag and operates from its own AAA battery, leaving the vehicle electrical system untouched during tests. It delivers results in milliseconds, freeing up bench space and eliminating the need for a heavy load bank. Firmware updates are supported, extending the tool’s coverage as new battery standards appear. The package includes the tester, a user manual and three years of after-sales support.
