A Nissan Maxima uses a conventional 12-volt automotive battery, not a high-voltage hybrid pack.
The exact size and chemistry depend on the model year and market. Typically this is a standard 12V flooded lead-acid battery, with some replacements offering an AGM (absorbent glass mat) variant. The factory group size is usually one of a couple of common sizes, most often Group 24F or Group 35. Always verify the precise specification by checking the battery label or the owner's manual for your specific car.
Battery basics for the Maxima
Understanding the common options helps when replacing or upgrading the battery. The Maxima relies on a traditional 12-volt system for starting, powering lights, and running electronics. The exact group size and whether a flooded or AGM battery is used can vary by generation and region.
Common battery sizes for Maxima by generation
Battery group sizes aren’t universal across all years. Below are the two sizes most commonly seen when replacing a Maxima’s 12-volt battery.
- Group 24F — a widely used size for mid-size sedans, typically offering about 60–70 Ah with cold-cranking amps in the 550–750 range, depending on the manufacturer.
- Group 35 — another common option for many North American sedans, with roughly 60–70 Ah and CCA around 550–750 depending on the brand.
When replacing, always use the group size, CCA, and reserve capacity values specified by Nissan for your model year and trim. The battery label or the owner's manual provide the exact requirements.
How to verify the exact battery for your Maxima
To be certain you’re buying the right battery, confirm the specifications using these steps.
- Inspect the current battery: the label will show the group size (such as 24F or 35) and the CCA rating.
- Refer to the owner's manual or Nissan’s official service information for your exact year and trim.
- Provide your vehicle’s VIN to a dealer or auto parts retailer to retrieve the OEM-spec battery for your car.
- When purchasing, choose a battery that matches or exceeds the OEM voltage (12V) and the required CCA/RC values.
If you’re unsure, a professional at a Nissan dealer or trusted auto parts shop can confirm the correct battery size for your specific Maxima.
Tips for replacing and maintaining the Maxima battery
Replacement should follow proper safety precautions: wear eye protection, disconnect the negative terminal first, and ensure the engine is off. After installation, reset or relearn any electronic systems if required by your model, and have the charging system checked to ensure the alternator is maintaining the battery properly.
Summary: The Nissan Maxima uses a conventional 12-volt lead-acid battery, not a hybrid pack. The exact group size is year- and market-dependent, with Group 24F and Group 35 being the most common options. Always verify the specifications on the battery label or in the owner’s manual and replace with a unit that meets or exceeds the OEM ratings.
