The shelf life of polymer batteries is typically 1–3 years, primarily determined by storage conditions and initial state.
Key influencing factors
1. Battery Level: Optimal storage level is 30%–50%. Storing at full charge or completely discharged accelerates aging.
2. Ambient Temperature: Prioritize dry environments between 0–25°C. High temperatures (above 30°C) significantly shorten lifespan.
3. Battery Quality: New, high-quality cells have longer storage life. Aged or inferior cells degrade prematurely.
Storage Precautions
Avoid prolonged storage in fully charged or depleted states; adjust to an appropriate charge level before storage.
Keep away from high temperatures and humid environments; do not store with metal objects to prevent short circuits.
For long-term storage (over 6 months), recharge every 3–6 months to maintain a charge level of 30%–50%.
