Detailed Testing Protocol

Phase 1: Initial Capacity Testing

The initial capacity test establishes baseline performance characteristics using controlled discharge at 0.2C rate (approximately 420mA for a 2100mAh battery) to the manufacturer's specified cutoff voltage of 1.0V. This test validates the claimed capacity of 2100+ mAh and establishes the voltage discharge profile characteristic of lithium-ion technology.

Phase 2: High-Drain Flash Performance

Professional speedlight testing evaluates the batteries' ability to provide high-current pulses required for flash operation. Using a Canon Speedlite 600EX-RT set to maximum power, the test measures total flash count, average recycle time, and current draw characteristics until battery depletion. Success criteria require ≥500 full-power flashes with <4-second recycle times.

Phase 3: Continuous Load Testing

Continuous load testing simulates LED panel operation and camera usage with constant current loads ranging from 0.5A to 2.0A. This phase evaluates runtime, voltage regulation under load, and efficiency characteristics critical for sustained photography operations.

Phase 4: Temperature Performance Evaluation

Temperature testing assesses battery performance across the claimed operating range from -20°C to +55°C. Capacity measurements at each temperature point determine the temperature coefficient and validate cold-weather performance claims.

Phase 5: Cycling Endurance Testing

The cycling endurance test employs automated charge/discharge cycling to evaluate long-term capacity retention and cycle life. Following manufacturer charging specifications of 350mA to 1.5V followed by 0.1mA taper, the test continues until capacity falls to 80% of initial rating.

Phase 6: Real-World Photography Testing

Real-world testing scenarios include studio portrait sessions with continuous LED lighting, event photography with rapid flash sequences, and remote wildlife camera trap applications. These tests validate performance claims under actual photography conditions rather than laboratory simulations.
