The 2018 Nissan Pathfinder uses a standard 12-volt automotive battery. It’s typically a maintenance-free, lead-acid unit located in the engine bay. The exact group size and specifications can vary by market and trim, so checking the battery label or the owner's manual is essential.
Battery type, voltage, and chemistry
Understanding the basics helps ensure you replace the battery correctly and maintain reliable starting power for daily use.
- Voltage: 12 volts
- Chemistry: lead-acid (sealed, maintenance-free)
- Primary function: starting the engine and powering 12-volt electrical systems
The typical 12-volt battery in a 2018 Pathfinder is not a high-voltage battery or part of a hybrid system. It provides the necessary power for starting and running the vehicle’s accessories.
Is it AGM or standard flooded?
Most 2018 Pathfinder models use a standard maintenance-free flooded lead-acid battery. Some special markets or trims could use an AGM (absorbent glass mat) battery, but this is less common for base configurations. Always verify the specific battery type on the current unit or via the official Nissan specifications for your VIN.
How to identify the exact battery size for your model
To ensure you purchase the correct replacement, determine the exact group size and cold-cranking amps (CCA) required for your vehicle.
- Check the current battery’s label for the “Group Size” code and CCA rating.
- Consult the owner’s manual under the Electrical System or Specifications section.
- Use Nissan’s official parts catalog or contact a dealership with your VIN to confirm the correct battery size and specifications.
By following these steps, you’ll avoid buying an ill-fitting battery and ensure compatible terminal placement and hold-down fitment.
Replacement and installation tips
When replacing the battery, follow standard safety practices and proper installation steps to ensure a secure fit and clean connections.
- Disconnect the negative terminal first, then the positive terminal.
- Verify the replacement matches the required group size and CCA for your vehicle.
- Secure the battery with its hold-down clamp and ensure no loose connections.
- Dispose of the old battery at an approved recycling facility.
With proper care, the 2018 Pathfinder’s 12-volt battery should provide reliable service for several years under typical driving conditions.
Summary
In short, the 2018 Nissan Pathfinder uses a standard 12-volt maintenance-free lead-acid battery. The exact group size and CCA depend on market and trim, so verify the battery label, the owner's manual, or Nissan’s parts resources to ensure you get the correct replacement. Always follow safe replacement practices and recycle old batteries responsibly.
