Servicing Your Ranger Battery Your vehicle may have a Motorcraft maintenance-free battery. The Motorcraft maintenance-free battery does not require additional water during its life of service. The vents are part of the cover and cannot be removed. For longer, trouble-free operation, keep the top of the battery clean and dry. Also, make certain the battery cables are tightly fastened to the battery terminals. If you see any corrosion on the battery cables or terminals, remove the cables from the terminal and clean them both with a wire brush. You can neutralize the acid with a solution of baking soda and water. Reinstall the cables when you are done cleaning them, and apply a small quantity of grease to the top of each battery terminal to help prevent corrosion. Battery replacement If your original equipment battery requires replacement (under warranty), it may in some cases be replaced by a Motorcraft low-maintenance battery. The low-maintenance battery has removable vent caps for checking the electrolyte level and for adding water, if needed. NOTE: If your battery has a cover/shield, make sure it is re-installed after the battery is replaced. Check your battery's electrolyte level, at least every 12 months or 12,000 miles (20,000 km), in temperatures up to 90˚F (32˚C) and more often in temperatures above 90˚F (32˚C). Keep the electrolyte in each cell up to the "level" indicator. Do not overfill the battery cell. If the electrolyte level in your battery gets low, you can add plain tap water to the battery, as long as you don't use hard water, or water with a high mineral or alkali content. If possible, however, try to only fill the battery cell with distilled water. If the battery needs water often, have the charging system checked. 297
