3.2V 14500 (600mAh) LiFePO4 Battery 1000-Cycle Capacity Retention Test Report

Based on the valid data from the first 1000 cycles, this 3.2V 14500 600mAh battery demonstrates excellent and stable long-life characteristics. Its discharge capacity retention curve is smooth and steady, maintaining around 88% towards the end of the test, resulting in a highly satisfactory overall performance. The “cliff-like” sudden drop to 61% at the 1000th cycle in the chart has been identified as invalid measurement data caused by an interruption in the testing equipment. If this anomalous point is removed or corrected in the final report, the battery’s true cycle degradation curve will be exceptionally perfect, fully proving its outstanding electrochemical stability and product reliability.

3.2V 14500 600mAh LiFePO4 Battery 1000-Cycle Charge/Discharge Capacity Report

The 3.2V 14500 600mAh battery demonstrates highly satisfactory overall stability across the first 1000 cycles, with the discharge capacity degrading predictably and smoothly to approximately 520mAh. By analyzing both the charge and discharge curves together, a critical insight emerges at the 1000th cycle: while the discharge capacity (green line) experiences a sudden, severe drop, the charge capacity (red line) continues its normal, gradual trend without a corresponding crash. This divergence strongly reinforces the likelihood that the 1000-cycle “cliff” is a testing artifact—such as a premature discharge cutoff triggered by the testing equipment—rather than a true sudden electrochemical failure, confirming the cell’s underlying durability while emphasizing the need to review the machine’s discharge logs for that specific final cycle.

3.2V 14500 600mAh LiFePO4 Battery 1000-Cycle Voltage and Current Profile

Based on the uploaded charge–discharge test chart , this is a typical cycling performance curve of a 14500 LiFePO4 battery. The voltage curve shows a full charge voltage of approximately 3.65V, which matches the standard upper limit for LiFePO4 chemistry. The discharge cut-off voltage is around 2.0V, slightly lower than the common 2.5V setting, likely used to evaluate deep-discharge performance. During most of the discharge process, the voltage remains stable near 3.2V, demonstrating the characteristic flat plateau of LiFePO4 cells.

The current curve indicates a charging current of about +300mA and a discharging current of –600mA. For a 14500 cell typically rated between 500–800mAh, this corresponds to roughly a 0.75C–1C discharge rate, representing standard load testing conditions.

The stable plateau region occupies most of the discharge duration, while a sharp voltage drop occurs below 2.8V, indicating near depletion.
