12V Battery Tester for Cars and Boats

The LUOM KW208 is a digital analyser built for 12-volt lead-acid batteries rated from 100 to 2000 CCA. It suits owners of cars, trucks, motorcycles, SUVs and marine craft who want a quick health check without removing the battery from the vehicle.

100-2000 CCA Range and Multi-Standard Support

The tester covers the full 100-2000 CCA span and reads CCA, BCI, CA, MCA, JIS, DIN, IEC, EN and SAE ratings. It handles regular flooded, AGM flat plate, AGM spiral and gel chemistries, but it cannot assess batteries outside the stated CCA window or non-lead-acid types.

Polarity-Reverse Protection and Instant Results

Clips connect directly to the terminals and the unit powers on automatically, delivering health, charge, cranking and alternator data in seconds with a claimed 99.9% accuracy. Reverse-polarity protection prevents damage if the leads are swapped.

Questions about this item

Will the 12 V tester work on the 6 V motorcycle battery I keep in the garage?

The unit is rated for 12 V batteries only, so a 6 V battery cannot be tested with it.

How do I confirm the STM-32 chip is giving the claimed 99.9 % accuracy after I hook it up?

Compare the displayed CCA value and internal resistance against the battery's rated CCA; a Good/Recharge/Replace suggestion matching the known condition verifies correct operation.

The listing mentions clips and a manual — do I need to buy AAA cells or any cables separately?

The tester draws power from the battery under test, so no AAA cells are required; the supplied clips and manual are the only items in the box.
