6V 12V Battery Analyser

The LUOM KW650 is a digital tester for 6 V and 12 V lead-acid batteries rated from 100 to 2000 CCA. It suits technicians and DIY owners who need fast health checks on cars, boats, motorcycles or lawn equipment. The device reads voltage, internal resistance, cold-cranking amps and overall condition in milliseconds. Results show as Good, Recharge or Replace with a health percentage.

100-2000 CCA Test Range

Conductance technology driven by an STM-32 chip delivers over 99.5 % accuracy referenced to Midtronics benchmarks. The unit handles flooded, AGM flat-plate, AGM spiral and gel chemistries both in and out of the vehicle. Maximum input and output current is 15 A and resistance measurement reaches 1 M ohm. Batteries below 100 CCA or above 2000 CCA fall outside the calibrated range.

One-Click Readiness Key

A patented single-button function gives instant emissions-readiness status on all OBD II petrol and diesel vehicles. The tester measures 5.94 by 3.22 by 2.2 inches and runs on AAA cells. It includes a user manual and carries UL/CSA certification. Buyers who need integrated charging, printing or wireless logging should look elsewhere.

Questions about this item

Will the KW650 test the 12 V starter battery in my older boat without removing it?

Yes, the tester works on 6 V and 12 V batteries from 100 to 2000 CCA and can test them in or out of the vehicle, so the boat battery can stay connected.

How do I confirm the KW650 is giving reliable readings after I connect it?

The unit shows voltage, internal resistance, cold cranking amps, health percentage and charge status, then displays a clear Good, Recharge or Replace verdict backed by 99.5 % accuracy.

What comes in the box and do I need to buy anything else to start testing?

The set includes the KW650 tester, a user manual and the required AAA batteries, so no extra purchase is needed for basic battery testing.
