What type of battery does a 2018 Ford Explorer take?
The 2018 Ford Explorer uses a 12-volt automotive battery. In most trims it’s a standard maintenance-free lead-acid battery, but models equipped with Ford’s Auto Start-Stop technology may employ an Absorbed Glass Mat (AGM) battery to handle frequent cycling.
Battery types you might encounter in the 2018 Explorer
Two configurations cover most 2018 Explorers, depending on powertrain and options. The baseline is a conventional 12-volt lead-acid battery; if the vehicle has Start-Stop, the system typically uses an AGM battery for improved durability and cycling tolerance.
- Maintenance-free 12-volt lead-acid battery (standard on most trims)
- Absorbed Glass Mat (AGM) battery (used on models with Ford Auto Start-Stop technology)
To confirm which type is in your vehicle, check the battery label for "AGM" or refer to the owner's manual or dealership records.
Identifying the correct battery size and replacement requirements
Battery size is specified by the group size and cooling amps. The exact group size for your 2018 Explorer depends on trim and engine. The battery label on the unit and the owner's manual both list the required group size and CCA (cold-cranking amps). If your vehicle has Start-Stop, ensure you choose an AGM-compatible battery with an appropriate CCA rating.
Replacement and maintenance tips
When replacing or maintaining the battery, follow manufacturer guidelines and safety precautions to avoid injury and electrical damage.
- Disconnect the negative (-) terminal first, then the positive (+) terminal to prevent short circuits.
- Replace with a battery that matches the specified group size and CCA rating; use the AGM type if your Explorer has Start-Stop.
- Keep terminals clean and tight; apply terminal protectant to limit corrosion.
- Dispose of the old battery properly at an authorized recycling facility.
If you’re unsure about the correct battery for your 2018 Explorer, consult the owner's manual or a Ford dealer or a trusted parts retailer with your vehicle identification number (VIN) to confirm the exact requirements.
Summary
In short, a 2018 Ford Explorer typically uses a 12-volt maintenance-free lead-acid battery. If your model is equipped with Auto Start-Stop, the vehicle is more likely to use an AGM battery. Always verify the exact group size and CCA from the battery label or the owner's manual and replace with the correct type to ensure optimal performance.
