Instant Battery Status Diagnosis: The KVB02 car battery checker is a high-performance battery checker that can simultaneously measure voltage (V), internal resistance (I.R), CCA, SOH, and SOC. Battery diagnostic results are displayed intuitively as "Good," "Caution," "Needs Charging," or "Needs Replacement," making it ideal for determining car battery deterioration and replacement timing.

Wide Battery Compatibility: This battery tester is compatible with car batteries in automobiles, motorcycles, trucks, boats, ATVs, golf carts, and more. It's a general-purpose car battery checker compatible with lead-acid (STD), EFB, AGM, and GEL batteries, making it suitable for a wide range of uses, from home use to maintenance. *Lithium batteries are not supported.

High-Precision Diagnosis with 4-Wire Measurement: This car battery tester employs a 4-wire Kelvin connection method, minimizing the influence of wire resistance and enabling high-precision internal resistance and CCA measurements. It provides reliable measurement results for automotive maintenance, pre-inspection checks, and daily battery checks.

Safe Design: This car battery tester complies with multiple international standards, including JIS. With safety features such as reverse connection, overcurrent, overvoltage, short circuit, and overheat protection, you can safely diagnose your battery.

Compatible with both in-vehicle and external batteries: Supports both in-vehicle battery testing (without removing the battery) and external battery testing (with removal). Easy to use, this car battery checker is perfect for daily checks, repair shops, and DIY users.
