What type of battery does a 2018 Ford Edge use?
The 2018 Ford Edge uses a 12-volt automotive battery to start the engine and power electronics; most trims use a standard flooded lead-acid battery, while models with Auto Start-Stop may use an AGM (Absorbent Glass Mat) battery.
In this explainer, we break down what that means for owners, how to identify the exact type on your VIN, and what to know when replacing or maintaining the battery. Because specifications can vary by engine and trim, always check the label on the battery or the owner's manual for the exact spec.
Battery types in the 2018 Edge
Below is a quick comparison of the two common battery types you might encounter in this model. Understanding the differences helps you choose the right replacement and understand maintenance needs.
- Flooded lead-acid batteries are the traditional, inexpensive option found in many vehicles. They are sealed to limit gas release and are adequate for most driving, but they may require electrolyte checks and are less tolerant of deep cycling over time.
- Absorbent Glass Mat (AGM) batteries use a fiberglass mat to hold the acid in place, are more resistant to vibration, tolerate deeper cycling better, and are typically used in vehicles with start-stop systems or high electrical load. They often cost more upfront but can offer longer life and better performance in demanding conditions.
Bottom line: If your Edge has Start-Stop, it is more likely to use an AGM; otherwise you’ll typically find a flooded lead-acid battery. Always verify the exact type with the battery label or VIN-specific Ford documentation.
How to identify the battery type in your Edge
Use these steps to confirm the battery type on your specific vehicle. The following method helps you avoid purchasing the wrong type and ensures compatibility with your charging system.
- Locate the battery under the hood and read the label on the top or side for the type (flooded vs AGM) and CCA rating.
- Check for an Auto Start-Stop badge or feature list in the vehicle's specifications. Presence of Start-Stop increases likelihood of AGM in many Ford models.
- Consult the owner's manual's specifications page or the battery replacement section for the recommended battery type and group size.
- If you still aren't sure, contact a Ford dealership or use the VIN to pull exact factory options and battery spec from Ford's parts catalog.
- When in doubt, have a professional inspect the battery to confirm the correct type and ensure proper fit and electrical compatibility.
Having the correct battery type helps ensure reliable starting, proper charging through the alternator, and the long-term health of your Edge’s electrical system.
Battery maintenance and replacement tips
Maintenance and replacement guidelines help prolong battery life and ensure reliable performance. Here are practical tips for the 2018 Edge:
- Keep terminals clean and tight; corrosion can impede charging and starting.
- Test the battery voltage periodically or during service visits; typical resting voltage should be around 12.6 volts for a healthy 12V battery.
- For AGM batteries, avoid deep discharge; recharge promptly if voltage drops significantly.
- When replacing, match the OEM recommended group size and CCA rating; if you’re in a cold climate, prioritize higher CCA ratings.
Regular checks and using the proper replacement battery will help avoid unexpected breakdowns and ensure your Edge operates smoothly.
Summary
Most 2018 Ford Edge models use a 12-volt automotive battery. If your vehicle has Auto Start-Stop, an AGM battery is more likely. Always verify the exact type and specifications from the battery label, the owner's manual, or a Ford dealer using your VIN. Correctly identifying your battery type ensures reliable starting and optimal electrical performance.
