The 2018 Nissan Titan uses a standard 12-volt automotive battery, and the OEM replacement is typically Group Size 24F. Replacement batteries usually run around 70–78 amp-hours (Ah) with about 700–800 cold-cranking amps (CCA), depending on the brand and model.
To ensure a perfect fit, check the label on your current battery or consult the owner’s manual or a Nissan dealer. Battery group size is the primary compatibility factor, and some aftermarket options may use Group 24 or 24F depending on terminal configuration. Always match or exceed the original equipment specifications for your specific trim and climate.
Battery size and specifications
Below are the common specifications you should look for when replacing the battery in a 2018 Titan. These figures reflect typical OEM guidance and aftermarket compatibility for this model year.
- Group size: 24F (commonly listed as the aftermarket or OEM replacement for most 2018 Titans)

How to verify the correct battery
Compare the labeling on your current battery to the group size and specs listed in your manual. If you’re replacing an old battery, a dealer or reputable auto parts store can confirm compatibility by year, make, model, and trim.
