The 2004 Nissan 350Z typically uses a Group 24F, 12-volt battery with about 600–700 cold-cranking amps (CCA), depending on the brand and exact specification.
In practice, battery group sizing matters for fit and performance. The 350Z’s battery sits in the engine bay and requires a specific hold-down and terminal layout, so choosing the correct Group size is essential for reliable starts and proper electrical function. OEM manuals commonly list Group 24F as the standard, though some retailers offer Group 24 or Group 35 as alternatives when 24F isn’t available; always verify the exact size on the existing battery label or in the owner's manual.
Common battery group sizes for the 2004 Nissan 350Z
Here are the sizes you’re most likely to encounter when replacing a 2004 350Z battery. Check your vehicle’s label and the replacement’s fitment specs before purchasing.
- Group 24F — The typical OEM-sized option for the 2004 350Z; 12V with standard CCA ratings around 600–700, depending on brand.
- Group 24 — A common alternative if 24F is out of stock; confirm dimensions and terminal orientation to ensure proper fit.
- Group 35 — Sometimes offered as an alternative by retailers; verify tray clearance and hold-down compatibility before choosing.
Concluding note: Always confirm the exact group size by checking the vehicle’s manual or the label on the current battery, and ensure the replacement matches or exceeds the engine’s cold-start requirements and fits the battery tray.
How to confirm the correct battery size
To be sure you get the right size, follow these verification steps before buying a new battery.
- Check the owner’s manual or a dealership parts fiche for the recommended Group size (commonly 24F for many 2004 Z33 models).
- Inspect the existing battery label for the Group size (e.g., Group 24F) and terminal arrangement.
- Measure the battery tray dimensions (length, width, height) and compare with the replacement’s dimensions.
- Verify hold-down fitment and terminal polarity to avoid clearance or wiring issues.
- When possible, consult the retailer’s fitment guide using your vehicle’s year, make, and model to confirm compatibility.
Concluding guidance: After identifying the correct group size, choose a battery with adequate CCA and reserve capacity for your climate and driving needs, and ensure the physical fitment is secure in the tray.
Summary
For most 2004 Nissan 350Z models, the standard battery group size is Group 24F, a 12-volt battery with roughly 600–700 CCA. Alternatives like Group 24 or Group 35 may be used if 24F isn’t available, but always verify fitment, terminal layout, and official specifications from the owner’s manual or battery label. In practice, confirming the exact group size and measurements before purchase helps avoid fitment issues and ensures reliable starting performance.
