Battery tester for 12 V systems

The Jansicotek KW208 analyses 12 V batteries rated from 100 to 2000 CCA. It covers regular flooded, AGM flat plate, AGM spiral and gel types. The tester works in-vehicle or out-of-vehicle without removing the battery. It is suited for cars, trucks, motorcycles, ATVs, SUVs, boats and yachts.

Thermals noise and power draw

The handheld unit draws its operating power from the battery under test and has no internal fan. Normal use produces no audible noise and negligible heat. Polarity-reverse protection prevents damage if the clamps are connected incorrectly.

Bundled accessories and software

The package includes the KW208 analyser and a printed user manual. The on-board firmware runs battery health, cranking and charging tests, then displays SOH, SOC, CCA value, voltage, internal resistance and a Good, Recharge or Replace recommendation. No external software or subscription is required.

Questions about this item

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

Clamp the red lead to the positive terminal and the black lead to the negative terminal; the tester powers on automatically and begins the health check without removing the battery.

Which consumable parts on the KW208 will need replacement over time?

The clamp cables and their spring contacts are the only wear items; replace them if the insulation cracks or the jaws no longer grip the terminals firmly.

At what CCA rating does the KW208 stop giving reliable results during repeated testing?

The analyser is rated up to 2000 CCA; accuracy of 99.5 % is specified within that range, so sustained use on batteries above 2000 CCA is the first limit you will reach.
