The Maxima uses a standard 12-volt automotive battery, not a high-voltage or hybrid pack.
In practice, replacement batteries for most Maxima models come in common 12V group sizes such as 24F or 35, with capacities around 60–70 amp-hours and cold-cranking amps (CCA) typically in the 500–750 range. Exact specifications depend on the model year, trim, and market, so always check the battery label or the owner's manual for the precise fitment.
Common battery sizes and specs
Before listing the typical options, note that exact fitment depends on the model year and regional market. The following are among the most frequently seen options for Nissan Maxima vehicles.
- Group Size 24F: widely used in many Nissan models; typical capacity about 60–70 Ah; CCA commonly in the 540–730 range depending on the manufacturer.
- Group Size 35: another common option in some markets; similar 60–70 Ah capacity with CCA often in the 600–750 range.
- Battery type: predominantly 12-volt lead-acid; most Maximas use flooded lead-acid; some trims or markets may specify an absorbed glass mat (AGM) battery.
- Voltage: 12 volts (standard automotive electrical system).
In short, for most Maxima models, a standard 12V lead-acid battery in group sizes 24F or 35 will fit, with about 60–70 Ah and a CCA rating appropriate to your climate and driving needs. Always verify the exact size and rating on the battery label or in the owner's manual.
Choosing the right battery for your Maxima
Before shopping, gather the exact requirements to ensure you purchase the correct unit for your year and trim. Use the following steps as a guide.
- Check the owner's manual or the current battery label for the recommended Group Size (e.g., 24F or 35) and the minimum CCA rating.
- If your Maxima has higher electrical demand (heated seats, premium audio, frequent short trips), you may benefit from a higher CCA or reserve capacity.
- Decide between flooded lead-acid and AGM: AGM offers better performance in certain conditions but costs more; stability and vibration resistance is improved in AGM.
- Match terminal configuration and polarity to the car’s battery cables and clamps to avoid fitment issues.
Always verify with the dealer, VIN-specific parts lookup, or the battery label to ensure compatibility for your exact model and market.
Summary: The Nissan Maxima uses a standard 12-volt automotive battery. Common sizes include 24F or 35 with roughly 60–70 Ah capacity and a CCA rating that varies by climate and trim. Verify the exact specification on the label or in the owner's manual, and consider AGM in markets or trims that require higher performance, though most models use a flooded lead-acid battery.
