The 2007 Nissan Altima most commonly uses a 12-volt Group Size 35 battery for replacement, but exact sizing can vary by engine and trim. Always verify with the current battery label or the owner's manual, or check Nissan’s parts catalog for your VIN.
The battery size, or group size, is chosen to fit the under-hood space and the terminal layout, as well as to meet the car’s electrical demands. While Group 35 is the standard target for many 2007 Altima models, your exact size should be confirmed from your existing battery or a VIN-specific parts lookup to ensure proper fit and performance.
Common battery group sizes for the 2007 Altima
Below are the group sizes you’re most likely to encounter when replacing a 2007 Altima battery. The exact size for your car is the one printed on the existing battery label or listed in Nissan’s VIN-based parts catalog.
- Group 35 — The most commonly used size for many 2007 Altima models, offering a good balance of fit, capacity, and cold-cranking performance.

How to verify the correct battery for your vehicle
To ensure you buy the correct size, follow these verification steps.
- Check the owner’s manual for the recommended battery group size and specs.
- Inspect the label on your current battery to read the group size (often displayed as a code like "Group 35").
- Use your VIN to look up the exact OEM specification in Nissan’s parts catalog or a reputable parts retailer.
- Confirm terminal type (top-post or side-post) and post spacing to ensure a proper fit with your cables.
Conclusion: After confirming the exact group size, choose a battery that matches or exceeds OEM CCA and RC ratings, and ensure a proper fit with your car’s cables and mounting hardware.
Replacement considerations
Think about performance, climate, and long-term reliability when selecting a replacement battery.
- Battery type: Most 2007 Altimas use a standard flooded 12V battery; AGM options are available but may require a higher price and potentially different charging profiles.
- Cold-cranking amps (CCA): Choose a rating that meets or exceeds OEM recommendations, especially in cold climates.
- Reserve capacity (RC): Higher RC helps with frequent starts and electronics; select a value that suits your driving habits and climate.
- Fit and terminals: Ensure the group size, terminal arrangement, and cable lengths match your vehicle.
- Warranty and recycling: Look for batteries with solid warranties and proper recycling programs.
Conclusion: A correctly sized battery with adequate CCA/RC and a solid warranty will deliver reliable starting performance across seasons.
Summary
For most 2007 Nissan Altima models, the target replacement battery is Group 35, a 12-volt unit that balances size, capacity, and cold-cranking power. Always verify the exact group size from the current battery label, your owner's manual, or Nissan’s parts catalog using your VIN before buying. When shopping, prioritize the correct group size, sufficient CCA and RC, and a strong warranty to ensure dependable performance and long-term reliability.
