The Nissan Altima generally uses a standard 12‑volt automotive battery in the correct group size for your year and trim. In most cases, you’ll encounter Group 24F or Group 35 as the common fit, but the exact size depends on the model year and options. Check your owner’s manual or the label on the current battery to confirm the proper size and specifications.
What the Altima needs in a battery
All non-hybrid Altimas rely on a conventional 12-volt lead‑acid battery to start the engine and power accessories when the engine is off. The key specs to match are group size, cold-cranking amps (CCA), and reserve capacity (RC). Modern Altimas typically use a maintenance‑free, either flooded or AGM battery depending on trim and electrical load. While AGM batteries are available, they are not always required unless you have high electrical demand or extreme climates. Always verify the exact fit for your year and engine.
Common battery sizes for Altima generations
To help you quickly identify which battery to buy, here is a quick reference of typical group sizes used across generations. Remember that exact fit can vary by engine, trim, and market, so always confirm with your VIN or the label on your current battery.
- 2007–2012 Altimas: Group sizes frequently seen include 35 or 24F, depending on engine and options. Verify the exact fit from the label.
- 2013–2018 Altimas: Group sizes commonly include 24F or 35; confirm with the original equipment label or owner’s manual.
- 2019–present Altimas: Group size often 35, with some configurations possibly using 24F if the electrical load is higher. Always verify for your specific trim.
Careful verification with the current battery label or manufacturer’s spec is essential to ensure a proper fit and reliable starting power in your climate.
How to identify the correct battery for your specific Altima
Use these steps to determine the exact battery you should buy for your car, especially if you’re shopping online or at a parts counter.
- Look for the Group Size on the current battery label or in the owner’s manual; note the exact group size shown (e.g., 24F, 35).
- Check the vehicle’s manual or Nissan’s parts catalog for the recommended CCA (cold-cranking amps) and RC (reserve capacity) for your year/engine.
- Measure the battery tray space and terminal layout if you’re considering a different brand or a slightly different group size; ensure fitment and terminal orientation match.
- Compare specifications across brands: choose a battery that meets or exceeds OEM values for CCA and RC, and prefer a quality flooded or AGM battery based on climate and electrical needs.
- Decide between flooded vs AGM: AGM offers better performance and resilience in extreme conditions or heavy electrical use, but is usually more expensive. Ensure the chosen option is compatible with your vehicle’s charging system.
- Choose a reputable retailer or brand and verify warranty terms before purchase; consider warranties of at least 2–4 years for peace of mind.
Following these steps helps ensure you pick a battery that fits properly and delivers reliable performance for your Altima.
OEM vs aftermarket considerations
When choosing a replacement, you have options that balance price, warranty, and performance. The main choices are OEM (Nissan Genuine Parts) and reputable aftermarket batteries. OEM batteries guarantee exact group size and fit and may come with factory-backed warranties. Aftermarket brands such as DieHard, Interstate, Bosch, Bosch, ACDelco, and Motorcraft often provide competitive pricing and strong warranties with similar performance. If you opt for AGM, confirm compatibility with your climate and electrical demands and check warranty terms.
In all cases, ensure the battery you purchase matches the group size, CCA, RC, and terminal layout required by your Altima. AGM is optional and typically reserved for higher-load situations or extreme weather; most everyday drivers will be well-served by a high-quality flooded battery as long as it meets the OEM specs.
Maintenance and installation tips
Proper installation and maintenance can extend battery life and prevent issues. Follow these guidelines to get the most out of your Altima battery.
- Disconnect the negative (-) terminal first and reconnect it last when replacing the battery.
- Ensure terminals are clean, tight, and free of corrosion; use terminal protectors or anti-corrosion washers if needed.
- Keep the battery secured to prevent vibration and mechanical damage; avoid tilting beyond manufacturer specifications.
- Regularly check the battery voltage and health, especially in cold climates; consider a battery with higher CCA for winter performance.
- Recycle the old battery at an authorized facility and obtain a replacement receipt for warranty claims.
Good installation practices and regular checks help prevent unexpected starts and prolong battery life.
Summary
For a Nissan Altima, choose a 12-volt battery that matches the recommended group size for your year and trim—most commonly 24F or 35—with sufficient CCA and RC for your climate. Verify the exact fit by checking the current battery label or the owner’s manual, then decide between a standard flooded or an AGM battery based on your electrical needs and budget. Whether you choose OEM Nissan Genuine Parts or a reputable aftermarket option, ensure compatibility, proper installation, and a solid warranty. Regular maintenance and correct disposal of the old battery complete a reliable replacement plan.
