{'sulphuric acid': [1, 1, 0, 1], 'acetic acid': [0, 0, 0, 1], 'acid': [2, 1, 4, 16], 'batteries': [1, 0, 0, 1], 'hydrochloric acid': [1, 0, 3, 0], 'nitric acid': [0, 0, 0, 2]}
The acid stored in batteries is sulfuric acid. Sulfuric acid is commonly used in batteries as the electrolyte, which helps facilitate the flow of electrons between the electrodes.
Option 2, nitric acid, is not typically used in batteries. Nitric acid is a strong oxidizing agent and is mainly used in chemical laboratories and industries.
Option 3, hydrochloric acid, is also not commonly used in batteries. Hydrochloric acid is a strong acid and is most commonly used in industries such as steel manufacturing and food processing.
Option 4, acetic acid, is a weak acid commonly found in vinegar and is not used in batteries.
Therefore, the correct answer is option 1, sulfuric acid.
