How We Test Battery

Our testing methodology for batteries involves a comprehensive evaluation of performance, safety, and longevity. We utilize standardized testing protocols to measure capacity, discharge rates, and charging times under various conditions. Each battery is subjected to rigorous stress tests to ensure reliability and safety, including thermal and short-circuit testing, to provide an accurate representation of real-world usage.

STEP 01 Initial Inspection

Each battery undergoes a visual inspection for manufacturing defects and packaging integrity.

STEP 02 Capacity Testing

We measure the actual capacity of the battery against its advertised specifications using specialized testing equipment.

STEP 03 Discharge Rate Evaluation

Batteries are tested for their discharge rates under various loads to determine efficiency and performance.

STEP 04 Charging Tests

We assess the charging time and heat generation during the charging process to evaluate safety and performance.

STEP 05 Cycle Life Assessment

Batteries are subjected to multiple charge and discharge cycles to determine their longevity and degradation over time.

STEP 06 Safety Testing

We conduct thermal and short-circuit tests to ensure that the batteries meet safety standards and can handle extreme conditions.
