12V 100-2000 CCA Battery Tester

The LUOM KW208 is a digital analyser for 12-volt lead-acid batteries rated between 100 and 2000 cold cranking amps. It suits owners of cars, trucks, motorcycles, boats and other 12V vehicles who want a quick health check without removing the battery. The unit tests flooded, AGM flat-plate, AGM spiral and gel types. Results include state of health, state of charge, CCA value, voltage and internal resistance.

15A 1M Ohm Measurement Limits

Testing is restricted to 12V systems and a maximum input or output current of 15 amps. Resistance measurement tops out at 1 megaohm, so higher-impedance circuits fall outside the range. The analyser draws power from the battery under test and requires no external supply. Polarity-reversal protection prevents damage if the clips are swapped. Operating noise spans -10 to +56 decibels.

±6 mm Accuracy with UL/CSA Certification

The manufacturer states an accuracy of ±6 millimetres and a testing precision up to 99.9 percent, referenced to Midtronics benchmarks. The device carries UL and CSA safety certifications. It ships with a set of clips, a user manual and a one-year guarantee. AAA batteries power the internal electronics. The compact housing measures 5.98 by 3.39 by 1.77 inches.

Questions about this item

Should I choose a tester that handles 100 CCA or one that goes up to 2000 CCA?

The KW208 covers the full 100 to 2000 CCA range in one unit, so you do not need to pick a specific capacity; it works on any 12V battery within that span.

What does the 100-2000 CCA rating tell me when I test a battery in my car?

It means the tester can measure cold-cranking amps on any 12V battery rated between 100 and 2000 CCA, giving you the actual CCA value, state of health and state of charge in seconds.

What interface does the KW208 use and what does it limit?

It connects directly to the battery terminals with clamps; the 15A maximum input and output current and 1M ohm resistance range define the electrical limits of the test circuit.
