12V 100-2000 CCA Battery Tester

The Jansicotek KW208 is a digital analyser for 12-volt lead-acid batteries rated between 100 and 2000 cold cranking amps. It evaluates flooded, AGM flat-plate, AGM spiral and gel types using standards such as CCA, BCI, CA, MCA, JIS, DIN, IEC, EN and SAE. The handheld unit suits vehicle owners and technicians who want a quick health, cranking and charging check without removing the battery.

Replaces Basic Voltage Meters

A simple multimeter only shows open-circuit voltage; this tester adds internal resistance, state of health, state of charge and a pass, recharge or replace recommendation. The jump is worth it when you need to confirm starter and alternator performance or detect a bad cell in seconds rather than guessing from voltage alone. Accuracy is quoted up to 99.9 percent with an STM-32 processor.

Check Battery Voltage Range && Terminal Access

Verify the battery is a 12-volt unit within the 100 to 2000 CCA window; 6-volt or higher-voltage systems are not supported. Ensure you can reach the terminals for the clamp connection, whether the battery sits in the vehicle or on the bench. Reverse-polarity protection is built in, but the clips must still make clean contact for a valid reading.

Questions about this item

What are the physical dimensions of the KW208 tester?

The unit measures 5.98 x 3.39 x 1.77 inches, making it compact enough to store in a glove box or tool bag.

How do I connect the KW208 to a 12V battery for testing?

Clamp the red clip to the positive terminal and the black clip to the negative terminal; the tester powers on automatically. Reverse-polarity protection prevents damage if the clips are swapped.

Does the KW208 require calibration or consumable parts over time?

No calibration schedule or replaceable components are specified. The device relies on its internal STM-32 chip for accuracy up to 99.9% and is ready to use whenever the clips are connected.
