KONNWEI KW700 6V 12V Car Battery Tester with Cranking and Charging System Test, CCA 100-2000, Multi-Standard, Backlit LCD

In a busy workshop or a home garage, the KONNWEI KW700 battery tester gives you a fast, accurate health check for 6V and 12V lead-acid batteries. It covers flooded, AGM (flat plate and spiral), GEL, and EFB types, making it suitable for cars, motorcycles, SUVs, light trucks, boats, and RVs. The tester measures State of Health (SOH), State of Charge (SOC), internal resistance, and actual CCA, then displays clear results on a backlit LCD. It also tests the cranking and charging systems, so you can verify the starter and alternator in one session.

Why choose it

The KW700 delivers professional-grade diagnostics without the complexity of a full lab scope. Its multi-standard CCA measurement lets you test almost any lead-acid battery on the market, while the integrated cranking and charging tests help you pinpoint whether a no-start is caused by the battery, starter, or alternator. The backlit screen remains readable in dim engine bays, and the rugged ABS housing withstands workshop chemicals. Reverse polarity protection prevents damage from accidental misconnection.

Ideal use cases

• Pre-purchase inspection of used vehicles
• Seasonal battery maintenance for motorcycles, boats, and RVs
• Quick alternator and starter verification after a no-start complaint
• Fleet preventive maintenance to reduce unexpected downtime
• DIY battery health checks before long trips

Good to know

The tester operates from the battery under test, so no internal battery is needed. It supports multiple languages, making it suitable for international workshops. The 80 cm cable allows comfortable reach across most engine bays. For best accuracy, test the battery at rest and at a moderate temperature. The KW700 is not intended for lithium-ion batteries.
