Battery type and replacement specifications
Most 2004 G35 models use a maintenance-free, sealed 12-volt lead-acid battery. The typical OEM replacement fit is Group Size 24F, with roughly 720 CCA. Variations can occur by market or production batch, so it’s important to check the battery label or the manual for the exact specification.
- 12-volt lead-acid battery, maintenance-free (sealed).
- Group Size: 24F is the primary OEM/aftermarket fit for many 2004 G35s; confirm on the current battery label.
- Cold-cranking amps (CCA): commonly around 720 A for this model.
When replacing, verify the exact group size and rating on your current battery label or in the owner's manual, since production runs can differ by market and year.
How to verify the exact battery for your car
To ensure you get the right battery, check the current battery and the owner's manual. You can also confirm via the VIN or a parts retailer.
- Inspect the battery label under the hood for Group Size (for example, 24F) and CCA.
- Consult the owner's manual or service manual for the OEM battery specs.
- Use the vehicle identification number (VIN) to look up the exact battery specification when buying from a dealer or reputable retailer.
- If you’re unsure, ask a professional at an auto parts store or a mechanic with details about your car (year, model, engine).
Verifying the exact specification ensures compatibility with your G35’s electrical system and avoids mismatched sizing or performance.
Replacement tips and considerations
When shopping for a replacement, consider these practical tips to ensure a proper fit, reliable performance, and safe installation.
- Choose a battery with the Group Size confirmed for your vehicle (primarily 24F for many 2004 G35s).
- Prefer a brand with a reputable warranty and readily available replacement parts.
- Ensure the battery is appropriate for your climate; higher CCA may be beneficial in cold locations.
- During installation, disconnect the negative terminal first and connect it last to reduce the risk of short circuits.
- Clean and secure the terminals and clamps; apply terminal protectant to reduce corrosion.
Following these tips helps ensure safe handling, proper fit, and reliable operation of the new battery in your Infiniti G35.
