Statement I: A hydrometer reading of 1.280 indicates a fully charged cell.

Statement II: A hydrometer can be used on a sealed maintenance free battery.

In the light of the above statements, choose the correct answer.

  • A.Both Statement I and Statement II are incorrect
  • B.Statement I is incorrect but Statement II is correct
  • C.Statement I is correct but Statement II is incorrect
  • D.Both Statement I and Statement II are correct

Answer: C

The density figure is correct, but a sealed battery has no removable vent plugs and cannot be sampled. Such batteries are assessed by voltage, load or conductance instead, and some carry a built in indicator for one cell only. The order in which the effects act is what decides the outcome, so it is worth establishing first. A symptom that appears under one condition and not another is what narrows the diagnosis quickly.
