12V 100-2000 CCA Load Tester

The LUOM KW208 is a digital battery analyser built for 12 V lead-acid units rated from 100 to 2000 CCA. It suits professional technicians and serious DIY owners who need quick health, cranking and charging checks on cars, motorcycles, boats and commercial vehicles without removing the battery.

Thermals Noise and Power Draw

The tester draws its operating power directly from the battery under test, so it adds no separate load to a workshop supply. Maximum input and output currents are 15 A, and the specified noise level spans -10 to +56 dB during normal operation.

Bad-Cell Detection and Multi-Standard Support

The decisive feature is the ability to pinpoint a bad cell directly while reporting SOH, SOC, CCA value and internal resistance against CCA, BCI, CA, MCA, JIS, DIN, IEC, EN and SAE standards. Buyers who need wireless logging or lithium-battery support should look elsewhere.

Questions about this item

How do I connect the KW208 clips to a 12V battery for an in-vehicle test?

Attach the red clip to the positive terminal and the black clip to the negative terminal; the tester powers on automatically and runs the selected test without removing the battery.

Which user-replaceable power cells does the KW208 require when the internal supply runs low?

The unit operates on standard AAA batteries that can be swapped out when depleted.

At what CCA rating does the KW208 reach its measurement ceiling during repeated load tests?

The tester supports battery ratings up to 2000 CCA; values above that limit fall outside its specified range.
