NOTE: Electrolyte levels for Absorbent Glass Mat (AGM) batteries should be checked every 25,000 miles or every two years.

Remove the battery cell caps (1).
Look through the battery cap holes to determine the level of the electrolyte in the battery (2). The electrolyte should be approximately 1 centimeter above the battery plates or until the hook inside the battery cap holes is covered.
