Battery health analyser

The Konnwei KW600 is a digital battery tester built for 12 V vehicle systems. It measures cold cranking amps from 100 to 2000 and capacity from 30 to 220 Ah. Workshops and owners use it to check state of health, state of charge and internal resistance quickly.

Thermals noise and power

The unit draws power directly from the battery under test within a DC 9 V to 16 V range. No external supply or cooling fan is required so operation is silent. Low current draw lets you test without draining a weak battery further.

Multi-standard diagnostics

Supported standards include CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB. The colour screen shows real-time voltage graphs for starting and charging system analysis. Firmware updates are free for the life of the tool and the interface offers ten languages.

Questions about this item

How do I connect the KW600 to a 12V battery and what step is often missed?

Clamp the red lead to the positive terminal and the black lead to the negative terminal; the tester powers on automatically from the battery voltage between 9V and 16V, so the step often missed is ensuring the clamps make clean metal contact before selecting the test standard.

What part of the KW600 will need replacement over time?

The internal 9V backup battery that retains settings and enables the graphical voltage monitoring when the vehicle battery is disconnected will eventually need replacement.

At what CCA or Ah limit does the KW600 stop giving reliable results during repeated testing?

The tester is rated for CCA 100 to 2000 and 30 to 220 Ah; readings outside this range are not supported and sustained testing at the extremes may cause the device to overheat and pause.
