Description
KONNWEI KW681 OBD2 Scanner and Battery Tester
The KONNWEI KW681 combines an OBD2 engine code reader with a 6V/12V battery and charging-system tester. It is a practical two-in-one tool for motorists, technicians and workshops that need quick engine fault checks and reliable battery-condition information without carrying separate testers.
Key Benefits
- Two tools in one: OBD2 engine diagnostics plus battery-system testing
- Reads and clears engine-related diagnostic trouble codes
- Displays live data, freeze-frame information and I/M readiness status
- Tests battery health, state of charge and internal resistance
- Performs cranking and charging-system tests to help assess the starter and alternator
- Colour TFT screen, built-in speaker and one-touch I/M readiness key
- Built-in DTC definitions and troubleshooting guidance
OBD2 Diagnostic Functions
The KW681 supports all 10 standard OBD2 test modes on compatible OBD2/EOBD/CAN vehicles. Functions include reading current, pending and permanent engine codes; clearing codes and the Check Engine Light; viewing live PCM data and freeze-frame data; checking emissions readiness; viewing O2-sensor and onboard-monitor results; initiating supported EVAP tests; and retrieving vehicle information such as VIN, CIN and CVN. Data can be recorded and played back, with selected reports printable through a connected Windows PC.
Battery, Cranking and Charging Tests
Test compatible 6V and 12V lead-acid batteries in or out of the vehicle. The tester reports voltage, measured cold-cranking performance, state of health, state of charge and internal resistance. It supports common flooded, AGM flat-plate, AGM spiral and GEL batteries, with CCA, BCI, CA, MCA, JIS, DIN, IEC, EN and SAE rating standards. The measurement range is 100–2000 CCA for the applicable standards, with DIN and IEC rated from 100–1400.

Compatibility and Important Notes
OBD2 diagnosis is limited to the vehicle’s emissions-related engine system; the KW681 is not a full-system ABS, airbag or transmission scanner. Vehicle and test support varies by make, model, year, region and ECU. Battery testing is intended for supported lead-acid battery types and ratings. Confirm the required vehicle or battery function before purchase. Manufacturer update software is available for compatible Windows computers.
