The 2018 Ford Explorer uses a 12-volt automotive battery. In most configurations this is a conventional flooded lead-acid battery, but models with Auto Start-Stop or specific options may require an AGM (absorbed glass mat) battery. Check your owner's manual or the battery label to confirm the exact specification for your VIN before purchasing a replacement.
Battery essentials for the 2018 Explorer
To determine the right battery for your vehicle, review key features and the battery label. The following factors guide most replacement decisions.
- Start-Stop capability: If your Explorer has Auto Start-Stop, Ford commonly recommends an AGM battery to handle repeated cycling without premature failure.
- Group Size and fit: The replacement battery must physically fit in the tray and connect correctly to the terminals. The current battery’s Group Size (such as 65, 96R, etc.) is listed on its label and in the owner’s manual.
- Cold-cranking amps (CCA) and reserve capacity (RC): Choose a battery that meets or exceeds the original CCA and RC specifications for your model; typical Explorer batteries fall in the 650–800 CCA range with RC around 100–120 minutes, depending on configuration.
- OEM vs aftermarket: Either an OEM Ford battery or a high-quality aftermarket equivalent that matches the group size, CCA, RC, and AGM requirements (if applicable) is acceptable.
Always verify by examining the current battery label or consulting Ford’s specifications for your VIN. When in doubt, a Ford dealer or a reputable parts retailer can confirm the correct replacement.
How to replace the battery safely
Replacing a 2018 Explorer battery is straightforward if you follow proper safety steps and use the correct type. Here are the general steps to guide you.
- Turn off the ignition, remove the key, and engage the parking brake; wear eye protection and gloves.
- Disconnect the negative (-) terminal first, then the positive (+) terminal; remove the hold-down clamp and lift the old battery out.
- Clean the battery tray and terminal connectors; inspect cables for corrosion and replace if needed.
- Install the new battery, secure the hold-down, reconnect the terminals starting with the positive, then the negative.
- Reconnect any accessories and start the engine to confirm proper operation; clear any warning codes if necessary.
Dispose of the old battery at an authorized recycling location or a retailer that accepts used batteries.
Summary
In short, the 2018 Ford Explorer uses a 12-volt automotive battery. Most models employ a conventional flooded lead-acid battery, while those with Auto Start-Stop may require an AGM battery. Verify the Group Size, CCA, and RC from the current battery label or the owner's manual, and choose a replacement that matches or exceeds Ford’s specifications. If uncertain, consult a Ford dealer or trusted auto parts professional.
