MacBook什么時候需要更換電池？MacBook電池能用多久？

如果你完全將 MacBook 充滿到 100%的電量，然后用到電池耗盡，這就為一次充電循環。如果電量剩余 50% 的時候你又讓 MacBook 充滿到 100%，那么當電量低于 50%的時候，就會又計算為一次充電循環。

所有 MacBook 的電池都和其它帶鋰離子電池的便攜物體一樣有著有限的充電循環次數。一旦設備電池超過充電循環次數的最大值，電池就會開始退化，這時候也就可以考慮換電池了。

那么如何在 Mac 上查看電池充電循環次數呢？

1.按住鍵盤上的 Option 鍵并點擊菜單欄上的蘋果 logo

2.從菜單頂部點擊“系統信息”，然后從側邊欄找到“電源”按鈕

3.最后在“電池狀況”找到“健康信息”

4.在這里你就可以看到 Mac 的電池循環次數，以下是蘋果所提供的各款 MacBook 的電池最大循環次數，大家不妨參考參考。超過這些循環次數，你就可以考慮換電池了。
