CNS BATTERY Factory maintains compliance with international certifications including UN38.3, IEC62133, CE, and RoHS, ensuring seamless market entry for client products.
Manufacturing Consistency
Production consistency represents a critical differentiator in battery procurement. Our automated manufacturing lines achieve capacity deviation within ±3% and internal resistance variation below 5mΩ across production batches. This precision enables reliable battery pack assembly without extensive cell matching procedures.
OEM Service Workflow
Phase 1: Requirement Analysis
The customization process begins with detailed technical consultations to understand application parameters including operating environment, load profiles, expected cycle life, and cost targets. Our engineering team translates these requirements into actionable cell specifications.
Phase 2: Prototype Development
Following specification confirmation, we produce engineering samples within 4-6 weeks for client validation. This phase includes performance testing, safety verification, and iterative refinement based on feedback.
Phase 3: Mass Production and Quality Assurance
Upon sample approval, production scales to agreed volumes with ongoing quality monitoring. Each batch includes comprehensive test reports documenting capacity, internal resistance, impedance, and safety performance metrics.
Industry Applications
Custom 18650 cells serve diverse sectors including consumer electronics, medical devices, industrial equipment, energy storage systems, and electric mobility. Each application demands unique performance characteristics that our OEM services accommodate through targeted cell chemistry and structural modifications.
