EN 50342-1 Lead-Acid Starter Battery Capacity and Performance Testing
The EN 50342-1 standard is a European technical specification that sets out the requirements for lead-acid starter batteries, specifically focusing on their electrical performance. This service ensures that these batteries meet stringent capacity and performance criteria as outlined in this standard. Conducted by our accredited laboratory, this testing guarantees compliance with international standards, thereby enhancing product reliability and market acceptance.
Our comprehensive battery cell performance tests are designed to evaluate various parameters critical for the proper functioning of starter batteries. These include open circuit voltage (OCV), internal resistance measurement, charging efficiency, discharge rate under different load conditions, cold cranking amperage (CCA), and high-rate discharge capacity. Our experts employ advanced instrumentation that adheres strictly to EN 50342-1 specifications to ensure accurate and repeatable test results.
The testing process begins with the receipt of the battery specimen from the client. The specimens are then prepared according to the standard’s requirements, ensuring no deviation in the methodology. Once ready, we perform initial checks such as visual inspection, measurement of dimensions, and recording of OCV under ambient conditions. Subsequently, the batteries undergo a series of discharge tests at specified intervals to measure their capacity retention over time.
For cold cranking amperage (CCA) testing, the battery is connected to a load designed to simulate engine starting conditions. The current drawn during this period is recorded and compared against the standard’s defined limits. High-rate discharge capacity tests follow similar procedures but involve discharging the battery at higher rates to assess its resilience under more demanding scenarios.
The results from these tests are meticulously documented, with detailed reports generated for each specimen tested. Compliance with EN 50342-1 is determined based on these test results and compared against the specified limits provided in the standard. Our team ensures that all discrepancies or non-compliances are noted down and discussed with clients to facilitate corrective actions.
By adhering strictly to EN 50342-1, our testing service not only meets but exceeds industry expectations for lead-acid starter battery performance. This service is invaluable for quality managers, compliance officers, and R&D engineers who need assurance that their products meet international standards before entering the market.
