–  Turn off the ignition and all electrical components.
–  Remove, if applicable, the protective stickers on the removal caps.
  Note
The sticker with the warning notes should remain on the Battery -A-.
–  Remove the removable caps from the cells.
–  Check the electrolyte level in the battery -A- → Chapter.
–  Dip the densometer into one of the cells and remove a large enough sample of electrolyte so as to make the buoy in the densometer float freely.
The greater the specific density of the electrolyte, the more the buoy will emerge from the electrolyte. The value can be read from a scale on the buoy.

  Note
Checking the electrolyte density immediately after topping the battery up with distilled water will give an incorrect measurement. Verify the density of the electrolyte only after the Battery -A-has been charged.
–  Check the cell caps and the O-Rings for damage. Any damaged components should be replaced.
–  Close the cells with their respective caps.
