Commercially available hydrometer
NOTE: If the electrolyte level is too high, the sulfuric acid/water mixture will leak to the outside of the battery and damage functional components in
the engine compartment.
-
If electrolyte level is too high (overfilling), i.e., it is above internal electrolyte level mark (lip of plastic flange) or external maximum line, draw off
excess electrolyte using commercially available hydrometer.

Draw off electrolyte using hydrometer until electrolyte level has reached lip of plastic flange or maximum line.
