When storing lithium-ion polymer (Li-Po) batteries , you need to consider their chemical properties to avoid performance degradation, damage, or even safety hazards caused by improper storage. The following is a scientific and practical storage guide: 1. Power management: avoid extreme charge states Ideal power range: During long-term storage, the battery voltage should be maintained at 3.7V–3.85V/cell (corresponding to approximately 40%–60% power). Reason: Full charge (4.2V/cell) will accelerate electrolyte decomposition and oxidation of positive electrode materials; full discharge (<3.0V/cell) may cause the negative copper collector to dissolve, causing permanent damage. Lipo Battery Short-term storage (<1 month): The power can be maintained at 20%–80%, but it still needs to be adjusted to an intermediate value for a long time.   2. Temperature control: slowing down the rate of side reactions Optimal temperature: 10°C–25°C (such as a cool and dry indoor en...
