FAQ
Q1: Do I need to strictly control the charge and discharge voltage of this cell in daily use, and what are the voltage ranges at different temperatures?
A: You must strictly follow the specified voltage range; otherwise, the cell’s service life will be affected and potential safety risks may arise. When the temperature is ＞0℃, the continuous operating voltage is 2.75V~4.25V and the pulse operating voltage is 2.5V~4.25V, with the maximum charging voltage not exceeding 4.25V and the minimum discharging voltage not lower than 2.5V. When the temperature is ≤0℃, the continuous operating voltage can be relaxed to 2.4V~4.25V and the pulse operating voltage to 2.0V~4.25V. It is recommended to set 2.4V as the cut-off voltage for low-temperature discharge to effectively protect the cell’s performance and lifespan.
Q2: How to properly use the cell in high and low temperature environments for outdoor work or long-term use, and what key points should be avoided?
A: For low temperature environments (≤0℃) : Preheat the cell before discharge, avoid direct high-rate discharge and use a discharge rate of ≤1C if possible. Prioritize maintaining the 2.4V cut-off voltage to prevent damage from over-discharging. For high temperature environments (≥40℃) : Avoid simultaneous charging and discharging, charge the cell in a cool and ventilated area, and limit the maximum continuous charging current to no more than 3C. After discharge, let the cell cool naturally to room temperature before recharging, and never charge or discharge it immediately after exposure to direct sunlight.
Q3: What precautions should be taken for daily storage of the cell, and what are the differences between short-term idle storage and long-term storage operations?
A: General storage requirements : Store the cell in a dry, ventilated environment free of corrosive gases, away from fire sources, heat sources and metal conductive materials. Store cells separately to avoid short circuits caused by contact between positive and negative poles.
Short-term idle storage (within 1 month) : Maintain the cell at 30%~50% SOC and control the ambient temperature at 0℃~25℃; frequent recharging is unnecessary.
Long-term storage (more than 1 month) : Control the ambient temperature at -10℃~30℃ with relative humidity ≤75%, and keep the cell at about 50% SOC. Complete a full charge-discharge cycle every 2 months to prevent cell aging due to low power. Unpackaged cells are recommended to be stored in their original sealed packaging for better protection.
Q4: What professional practical points should be noted when assembling this cell in series and parallel packs, and how to maintain the assembled packs in daily use?
A: Practical points for series and parallel pack assembly :
① Select cells of the same batch, identical internal resistance and consistent capacity for assembly; avoid mixing different batches to prevent unbalanced charging and discharging.
② Ensure reliable insulation at connection points and firm contact to prevent heat generation caused by poor contact.
③ Configure a matching protection board after assembly, which is adapted to the cell’s maximum charging voltage of 4.25V and the discharge cut-off voltage corresponding to the actual operating temperature range.
Daily maintenance of assembled packs :
① Regularly check the connection points for oxidation or loosening, clean and reinforce them in a timely manner.
② Ensure uniform temperature of all cells in the pack during charging and discharging to avoid local overheating.
③ Replace individual cells with the same specification in time if capacity attenuation occurs after long-term use, to prevent affecting the overall performance of the pack.
Q5: What parameters need to be noted for fast charging, and will daily use of fast charging significantly shorten the cell’s service life?
A: Practical fast charging parameters : Use fast charging only at room temperature (25℃) and within the cell’s SOC range of 10%~80%. Ensure the charging current matches the cell’s specifications (maximum continuous charging current of 5C at 20℃~50℃) and the charging voltage does not exceed 4.25V. It is recommended to let the cell stand for 5~10 minutes after fast charging before discharging.
Impact of fast charging on service life : Reasonable use of fast charging in accordance with the factory specifications will not significantly shorten the cell’s service life. The cell’s standard cycle life test (≥1500 cycles) includes conventional fast charging conditions. However, forced fast charging in high or low temperature environments, or continuous fast charging after the cell reaches 100% SOC, will accelerate cell aging. It is recommended to use standard charging (0.33C) as the main method in daily use, and fast charging only for emergency energy supplement.
