What Is a Battery Internal Resistance Tester?
A battery internal resistance tester (also known as a battery impedance tester) uses AC discharge testing technology to accurately measure voltage and internal resistance, enabling precise evaluation of battery health, capacity degradation, and technical performance to ensure stable operation in various applications.
Key Factors When Choosing a Battery Internal Resistance Tester
- 1. Measurement Range: Should cover the voltage range of your batteries (e.g., 12V, 24V, 48V) and resistance range.
- 2. Accuracy: High precision ensures accurate voltage and resistance measurements for better health evaluation.
- 3. Display & Data Storage: Clear display (LCD or color) and support for data logging and export.
- 4. Testing Methods: AC discharge method (more accurate health assessment) and DC discharge method (basic testing).
- 5. Safety: Over-voltage, over-current, and short-circuit protection to prevent damage.
- 6. Test Speed: Fast and stable measurement to reduce time costs.
- 7. Portability: Lightweight and easy to carry, with long battery life for field use.
- 8. Data Analysis: Trend analysis and report generation to help understand battery condition.
- 9. Brand & After-Sales Service: Choose a reputable brand with comprehensive support.
- 10. Application Scenarios: Telecom base stations, power systems, data centers, and UPS backup systems.
