The KZYEE KS21 Battery Analyzer has been designed so as to be a car battery tester that is able to test any 12 V batteries with a capacity of 100 to 1700CCA. It offers a quick and reliable test and analyzes a battery including CCA Value, Voltage, Inner resistance, and battery life percentage. The numerical results are very useful to check your battery condition, avoid any unexpected shutdown to your battery powered product. Also, it has great compatibility with a wide range of batteries like AGM, Gel Cell, Flood, Marine Deep Cycle batteries.

Why KS21?
1. Directly test the battery with loss of electricity, a full charge is not required before testing.
2. Tests all battery rating systems-CCA,EN,DIN,JIS,IEC, and others
3. Tests the batteries on the car directly- no need to remove the battery.
4. Directly detects bad cells.
5. Quick and accurate test result display in seconds.
6. Tests 12V charging system, advanced starter.
7. Quick starter analysis without disabling the ignition.
8. Does not emit light, heat or spark, or discharge battery-keeps operation safe.
9. Automatic temperature compensation.
10. Feature with reverse polarity protection: reverse connection may not damage the tester or affect the vehicle and battery.

  • 【CHECK BATTERY HEALTH 】Using the latest conductivity measurement method, the tester scans the battery and provides the results including health, state of charge, internal resistance and test result within 3 seconds (Excellent > 80%, Passable > 60%, Caution > 45%, Replace < 45%). Battery standards include CCA(SAE), IEC, EN, DIN, JIS#, etc.
  • 【Wide Range Of Application】 Works on 12V 100-2000CCA lead-acid batteries, including Regular Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB. It is also suitable for batteries of cars, motorcycles, trucks, ATVs, SUVs, boats, yachts, lawn mowers and even golf carts and lawn tractors.
  • 【CRANKING & CHARGING SYSTEM TEST】Presents you the test results (actual cranking voltage & cranking time) of the starter system in milliseconds to indicate whether the cranking system is working as expected. In addition, the battery load tester performs a comprehensive test of the 12V charging system to ensure that the alternator output is normal, the rectifier diode is working properly, and the charging current is under control.
  • 【SAFE PROTECTION DESIGN】The battery tester does not emit light, heat or spark and does not discharge the battery. It also has reverse polarity protection, overvoltage protection and automatic temperature compensation. In addition, it is safe for you, your cars, your batteries and the battery tester itself.
  • 【EASY TO USE】The sturdy and lightweight design, clear keypad and menu-driven operation make this battery alternator tester easy to use. The tactile click buttons provide good physical feedback of positive pressure even when you are wearing gloves. Even a beginner can operate this car battery tester effortlessly
