Businesses should adopt a structured evaluation framework:Performance Metrics: Test capacity at 0.2C and actual load profiles (≥98% of rating at 25°C). Measure internal resistance (DCIR) to assess heat generation and pulse performance. Validate cycle life (e.g., 80% capacity retention after 300–1,200 cycles at defined DoD).Safety & Compliance: Require certifications like UN38.3 (transport), IEC 62133-2 (portable...
