KONNWEI KW341 Automotive Battery & Charging System Tester — 6V/12V/24V Load Tester, CCA & SOH/SOC

Designed for mechanics, fleet technicians, and weekend DIYers, the KW341 delivers a clear picture of battery health and vehicle electrical performance without guesswork. It combines a load-style battery test with cranking and charging system checks, shows State of Health (SOH) and State of Charge (SOC), measures internal resistance and CCA, and outputs intuitive results like Good Battery, Replace, or Charge & Retest.

How does the KW341 tell if a battery needs replacing?

The KW341 runs a controlled load test and measures voltage, internal resistance, and cold cranking amps to determine battery condition. It compares measured values to the battery’s rated CCA and gives one of five easy-to-understand results that indicate if a battery can hold charge or should be replaced.

• Performs load-style testing for realistic starting conditions
• Measures internal resistance and actual CCA values
• Reports SOH and SOC to show remaining capacity
• Displays practical guidance: Good, Recharge, Replace, Bad cell, or Charge & Retest

Can this unit check the starter and alternator too?

Yes. The KW341 includes cranking and charging system tests so you can pinpoint whether a no-start condition is caused by the battery, starter, or alternator. The cranking test records minimum starting voltage and duration, while the charging test evaluates alternator output under idle and load, including ripple detection.

• Cranking test shows voltage drop and cranking time to detect starter faults
• Charging test measures alternator voltage, current response, and ripple
• Helps avoid misdiagnosis by separating battery and charging system issues

What battery types and standards does the KW341 support?

The KW341 is compatible with a wide range of battery chemistries and industry standards, making it suitable for motorcycles, cars, trucks, boats, and more. It tests 10–2000 CCA across 6V, 12V, and 24V systems and recognizes flooded, AGM (flat plate and spiral wound), Gel, EFB, and Lithium batteries.

• Supports 6V, 12V, and 24V systems for broad vehicle coverage
• Accepts CCA ranges from 10 to 2000 for small and heavy-duty batteries
• Compatible with CCA, JIS, EN, DIN, SAE, IEC, and GB standards
• Built-in reverse polarity protection and weak battery detection for safety

How easy and safe is the KONNWEI KW341 to operate?

The KW341 is battery-powered from the vehicle under test, so it requires no internal batteries and is always ready when connected. A backlit LCD with multiple language support, heavy-duty copper clamps, and protective circuits make the unit approachable for pros and hobbyists while minimizing user error.

• Powered by the tested battery—no internal batteries needed
• Backlit display with 12-language menus for clear operation
• Reverse polarity, overload protection, and secure copper clamps ensure safety
• Optional PC software and print support for record keeping and updates

Who is this for? The KONNWEI KW341 is aimed at anyone who needs reliable, repeatable electrical diagnostics: independent mechanics, auto repair shops, fleet managers, and informed DIY enthusiasts. If you maintain cars, motorcycles, trucks, boats, ATVs, or lawn equipment and want a single, professional-grade tool to test batteries and charging systems across 6V, 12V, and 24V platforms, the KW341 offers comprehensive results, safety features, and clear actionable guidance.
