你粒電是否鋰電是否用咗一段長時間呢因為本人也問過sony維修人員此問題佢話當鋰電用咗一段長時間喺需要放電的至於放電很簡單張粒充滿電的鋰電放入機內然後再放入相片或短片在機內不停播放直至無電為止大約放2至3次咁樣粒電會用得長久d此終喺一粒舊電池同新電池的內用性會爭D請自行放電測試本人也有放電事實上喺耐用咗

If you want to store it in a long period,you better fully charge it once before.......
After storing a long period,may be needs charge 2-3 times to optain full performance back again.

第二d電就唔知，但係sony infolithium電裡面有粒ic，專門記住一d資料，如果冇哂電就會遺失，到時部機認唔番粒電。

Are those lithium batteries still exhibiting the memory effect?
