The 12-volt battery in most Nissan Altima models is located in the engine compartment. This guide explains where to look and how to verify the exact position for your year and trim.
Locations can vary by generation and model year, so always double-check your owner’s manual or a service diagram if you’re unsure. This article provides a practical overview of the most common under-hood placements and safe steps for inspection or replacement.
Under-hood locations to check
Before you begin a search, note that the Altima’s battery is typically housed in the engine bay. In the majority of recent generations, it sits on the driver’s side near the strut tower, often beneath a plastic cover. Some older generations placed the battery closer to the passenger side. Use these pointers to locate it quickly.
- The driver’s-side area of the engine bay, near the strut tower and radiator support. Look for a rectangular battery case with two terminals (positive usually covered in red). This is the most common layout in newer Altima models.
- Occasionally, on older or certain trims, the battery may appear toward the passenger side of the engine bay, still across the width of the bay but on the opposite corner from the driver’s side.
If you still can’t find the battery after checking these spots, consult the owner’s manual for the exact diagram for your year/model, or contact a Nissan technician for guidance.
Replacing or servicing the battery safely
Steps to replace or service the battery
- Park on level ground, engage the parking brake, and turn off the engine. Open the hood and locate the battery as described above.
- Wear protective gloves and eye protection. Identify the negative (-) terminal first.
- Loosen and disconnect the negative battery terminal clamp, and move the cable away from the terminal.
- Loosen and disconnect the positive (+) terminal clamp, and move the cable away from the terminal.
- Remove any hold-down bracket or tray securing the battery, then carefully lift the battery out of the engine bay.
- Place the new battery in the tray, reinstall the hold-down, and reconnect the positive terminal first, then the negative terminal. Tighten clamps securely.
- Close the hood, start the vehicle, and verify that electrical systems function normally. If the car has memory settings (radio presets, etc.), you may need to reset them after replacement.
Note: Use a battery that matches the Altima’s required group size and rating. If you’re unsure, have a professional perform the replacement to avoid compatibility or safety issues.

For most Nissan Altima models, the 12-volt battery is housed in the engine compartment, typically on the driver’s side near the strut tower. Always verify with the owner’s manual, especially for older generations or specific trims.
