    How To Use Ez Battery Check Water Level Monitor:

    Proper safety measures should be used.

      1. Ensure that the battery is fully charged.
      2. The battery’s electrolyte level should be at the manufacturer’s recommended level.  Add distilled water if necessary.  Do not over fill.
      3. Remove the original vent caps and the install the Ez Check Battery caps.
      4. Note the level of the red float indicators and position the O rings even with the bottom of the red float indicators.
      5. The Ez Check cap is now ready to be monitored. When the red float indicator drops below the O ring, remove the small black cap on the fill tube and slowly add distilled water to the cell until the red float indicator rises above the O ring. Re-install the small black cap and you're done.

      Your batteries should be checked frequently to maintain the correct fluid levels
