Discharging: -20 to 60℃ (Must maintain < 60℃ during discharge)
Charger Operating Temperature: 0 to 60℃ (Recommended < 45℃ during charging)
Important Notes
State of Charge (SOC):
- Optimal: Maintain 40-60% (3.7-3.8V per cell)
- Prohibited: Long-term storage at <10% or 100% SOC (accelerates aging)
Temperature Control:
- 15-25°C: Ideal environment (<2% annual degradation)
- -20~45°C: Permissible range (requires SOC control)
- 50°C or <-30°C: Strictly prohibited (hazard risk)
Physical Protection:
- Avoid compression/impact (even with ABS casing)
- Keep away from metal objects to prevent short circuits
Recommendations:
For long-term storage (>1 month), perform periodic brief charge/discharge cycles to maintain lithium-ion activity and ensure normal energy output. We recommend performing a shallow cycle (30%→80%) every 3 months.
