引述

正式書寫注意：上述口語用法，如直接引述、語氣重複或停頓填充，在正式報告、學術論文或商業文件中應避免使用。正式文體應使用精確、客觀的表述，例如「電池電量耗盡」或「電池效能顯著下降」。

常見錯誤
What are common mistakes with "Battery"?Which "Battery" sentences look correct but are wrong?
×I need to buy battery for my remote.
✓I need to buy a battery for my remote.
在英文中，'battery' 是可數名詞，指單一電池時必須使用冠詞 'a' 或 'the'。
×My phone's battery is low, I need to charge my batteries.
✓My phone's battery is low, I need to charge my phone.
現代電子裝置（如手機、筆電）通常只有一個內建電池，複數 'batteries' 會讓人誤以為裝置內有多個可拆換的電池。應直接說為裝置充電。
×I need to change the battery in my remote.
✓I need to replace the battery in my remote.
'Change the battery' 語意上雖可理解，但更地道的說法是 'replace the battery'（更換電池）。'Change' 可能被誤解為改變電池類型或只是調整。為裝置 '充電' 應說 'charge the battery' 或 'recharge the battery'。
×The battery has no electricity.
✓The battery is dead. / The battery has no power.
描述電池沒電時，母語者通常說 'The battery is dead/flat/dead flat' 或 'has no power'，而非直譯的 'has no electricity'。'Electricity' 泛指電力，較不用於描述電池狀態。
×This power bank has a large battery cell.
✓This power bank has a large battery capacity. / This power bank uses high-capacity cells.
'Battery'（電池組）和 'cell'（電池單體）在技術上不同。一個 battery 可能由多個 cells 組成。日常對話中，描述電池『容量大』應說 'large/high capacity'，而非 'large cell'。
×He was charged with battery for hitting someone.
✓He was charged with assault for hitting someone.
'Battery' 在法律英文中確指『毆打罪』（非法觸碰），但日常新聞或一般對話中，更常用且廣泛理解的詞是 'assault'（攻擊、襲擊）。非法律上下文使用 'battery' 可能造成混淆。
