Correct answer

  • BSí, limpiar los bornes y protegerlos con grasa.Yes, clean the terminals and protect them with grease.
Explanation

With a so-called 'maintenance-free' battery we do not need to worry about the electrolyte, that is, the mixture of distilled water and sulphuric acid. We only need to pay attention to the terminal connections, so that they are tight, clean and covered with grease.
