3.5.2 Discharge Performance at Low Temperature
低溫放電性能
At -10±2℃ conditions, keep the battery for 2hrs, discharge the battery to 5.6V with 0.2C
constant current， After keep the battery 2hrs at 20±5℃，then check the appearance of
battery.
電池置於-10±2℃環溫下 2 小時，然後以 0.2C 電流恒流放電至 5.60V，再放在 20±5℃環溫下 2 小時
後，確認電池外觀.
--- The discharge capacity is above 80% of original capacity. The appearance is no distortion,
no explosion, no leakage.
---放電容量是原始容量的 80%以上.外觀應無變形、無爆炸、無漏液。
3.6 ESD
靜電保護
At direct discharge against the pins with ±4kv and over the housing with ±8kv. No damages
are allowed.
在直接探針接觸放電為±4kv，在空氣中為±8kv。不應有損壞。
