Ford NL3Z-10B759-E Battery

Removal: 1. Park on level ground, place transmission in Park, switch ignition off, remove key/fob, and engage the parking brake. 2. Wear eye protection and gloves, remove jewelry, and use insulated tools to reduce electrical risk. 3. HIGH-VOLTAGE WARNING: This vehicle has high-voltage systems; do not attempt to access or service high-voltage components unless you are trained and qualified-use the manufacturer's service disconnect procedure or have a qualified technician perform HV isolation. 4. Locate the low-voltage (12V) battery per the owner's manual and confirm which battery and connectors you will work on. 5. Allow the vehicle's electrical systems to fully power down per the owner's instructions before touching any connectors. 6. Disconnect the negative (ground) cable first using an insulated tool; isolate or cover the terminal to prevent accidental contact. 7. Disconnect the positive cable next and isolate that terminal as well. 8. Remove any covers and the battery hold-down hardware (retain fasteners and parts for reinstallation). 9. Lift the battery straight out of the tray using safe lifting technique and keep it upright to avoid spillage. 10. Inspect the tray, cables, and terminals; clean corrosion with appropriate cleaners and a brush while wearing PPE. 11. Store and transport the old battery upright and take it to a proper recycling/disposal facility per local regulations. Installation: 1. Verify the replacement battery is the correct type, orientation, and is adequately charged for the vehicle. 2. Place the battery onto the tray in the proper orientation so cables reach terminals without strain. 3. Reinstall the battery hold-down hardware and secure the battery so it does not move (do not overtighten). 4. Connect the positive cable first, ensuring a clean, fully seated connection. 5. Connect the negative (ground) cable last and ensure it is secure and free of corrosion. 6. If used, follow the manufacturer's procedure to restore any high-voltage service disconnect, or have a qualified technician perform that step. 7. Power up the vehicle and observe the instrument panel for warnings; follow any required manufacturer procedures for battery registration or system checks. 8. Verify operation of lights, accessories, and vehicle start/energize functions; recheck terminal tightness after initial use. 9. Dispose of packaging and return the old battery to a recycling center or the parts supplier. Repair tip: Apply a thin, appropriate terminal protectant to connections to slow corrosion and keep fasteners snug but not over-torqued.
