How to say "battery" in Japanese

  Take the battery off the machine.
• 電池でんちJLPT N2approx.Common

• 放列ほうれつCommon
  nounNot an electrical battery: it means a row of artillery pieces — or cameras — lined up to fire, and also the barrage such a line delivers.
• 中隊ちゅうたいCommon
  nounA military term: primarily 'company', with 'battery' as its artillery counterpart. It has nothing to do with electrical batteries.

• 台場だいばCommon
  nounAn abbreviated term for a fort or fortified battery — a gun emplacement built to hold artillery, not an electrical battery.

For an electrical battery use 「バッテリー」 (the loanword, as in cars and phones) or 電池 (batteries and cells); 放列 is a firing line of guns or cameras, 中隊 an artillery company, and 台場 a fortified gun emplacement.
