Home/Taiwanese Mandarin/All pairs/七號電池 vs 四号电池
AAA battery · Preferred written form
Preferred written form The two preferred forms differ by a single character. In Taiwan the standard term is 七號電池; on the Mainland it is 四号电池 - both point at “AAA battery”.
Taiwan’s Ministry of Education dictionaries record 七號電池、四號電池 for this concept. The Mainland standard is among them - the difference is which form each side makes the default.
Neither term carries an HSK or TOCFL level in this table - this pair is dictionary-recorded, not syllabus-derived.
Pair source: CC-CEDICT’s explicit “Taiwan/PRC equivalent” notes.
