KONNWEI KW650 Battery Analyser

The KONNWEI KW650 tests 6V and 12V lead-acid batteries rated from 100 to 2000 CCA. It covers regular flooded, AGM flat plate, AGM spiral and gel types found in cars, motorcycles, boats and lawn mowers. The STM32 processor delivers over 99.5 percent accuracy in milliseconds. Results include voltage, internal resistance, CCA value, state of health and state of charge.

Compact Handheld Design

The unit measures 2 by 7 by 12.5 centimetres and fits easily in a glovebox or tool drawer. A colour screen shows live voltage waveform analysis so users can spot irregularities in real time. Polarity-reverse protection and a warning light prevent damage from incorrect hook-up. Tests run in-vehicle or out-of-vehicle without removing the battery.

Upgrade From Basic Load Testers

The KW650 replaces simple voltage-only checkers by adding waveform capture, multi-standard support and on-screen replacement advice. It supports CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB standards plus twelve languages. The jump is worth it when you need professional-grade diagnostics and data logging for preventive maintenance.

Questions about this item

What test standards does the KW650 support for 100-2000 CCA batteries?

The KW650 supports CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB standards for testing 6V and 12V batteries rated from 100 to 2000 CCA.

What are the physical dimensions of the KW650 tester?

The unit measures 12.5 cm in height, 7 cm in width and 2 cm in depth, making it compact enough to store in a glove box or tool bag.

How do you perform a battery test with the KW650, and what common mistake should be avoided?

Connect the clamps to the battery terminals — red to positive, black to negative — select the battery type and standard, then press the test key; the built-in polarity-reverse protection alerts you if the clamps are reversed, which is the step most often missed.
