Typically a Group 24F battery is used in the 2008 Nissan Altima; some V6 configurations may require Group 35. Always verify on the battery label or in the owner's manual.
In practice, the exact size depends on engine option and market. The two most common group sizes you’ll encounter for the 2008 Altima in the United States are Group 24F and Group 35. Checking the current battery’s label or the official Nissan specifications will confirm the correct size for your car.
Common battery group sizes for the 2008 Altima
The battery size is defined by a "group size" that matches the fitment in the engine bay and the electrical load the car expects. Here are the sizes most often used on this model year.
- Group 24F — widely used on many 2008 Altima models with the 2.5L engine; typical cold-cranking amps (CCA) around 550–700 and capacity (Ah) around 60–78, depending on the manufacturer.
- Group 35 — used on some trims or when a higher CCA is preferred; typical CCA roughly 640–750 and capacity around 70–75 Ah, again varying by brand.
When replacing, matching the same Group Size is essential for proper fitment, and opting for a higher CCA/AH rating can improve reliability in extreme weather.
How to confirm the right size for your Altima
- Check the current battery for a label that shows the group size (for example "Group 24F" or "Group 35") and the CCA/AH ratings.
- Consult the owner's manual or the Nissan dealership/service website for the exact recommended battery group size for your trim and engine.
- If replacing, choose a battery with the same Group Size or a higher CCA rating, ensuring it fits physically in the tray and maintains proper terminal orientation.
- Have the installation performed with proper safety precautions and dispose of the old battery responsibly.
As general guidance, if you are unsure, rely on a professional technician or use a reputable online parts database to verify the correct size for your specific VIN.
Summary
The 2008 Nissan Altima typically uses Group 24F or Group 35 batteries, depending on engine and configuration. Verify the correct size by checking the existing battery label or the owner's manual, and when shopping for a replacement, match the group size and meet or exceed the OEM CCA rating for reliable starting performance in all weather.
