The cost to replace a Altima's battery typically ranges from $250 to $650, including both the part and professional installation. The final price depends heavily on the battery type, your vehicle's specific model year, and where you purchase it.
The primary factor is the battery's Group Size, which refers to its physical dimensions and terminal placement. Most modern Nissan Altimas use a Group 35 battery. You'll choose between a standard flooded lead-acid battery or an Absorbent Glass Mat (AGM) battery. AGM batteries, common in cars with Start-Stop technology for better fuel economy, are more expensive but offer superior performance and a longer lifespan.
Here’s a breakdown of average costs from different sources:
| Battery Type / Source | Estimated Price Range (Part Only) | Estimated Installed Price |
|---|---|---|
| Standard Flooded (Group 35) | $120 - $220 | $180 - $320 |
| AGM (Group 35) | $200 - $350 | $300 - $500 |
| Auto Parts Store (e.g., AutoZone) | $130 - $300 | $200 - $400 (with free installation) |
| Dealership | $250 - $450 | $400 - $650 |
| Online Retailer (e.g., Amazon) | $100 - $280 | N/A (DIY installation) |
Labor costs for installation are usually between $50 and $100. Many auto parts stores like AutoZone or Advance Auto Parts will install a battery you buy from them for free, which can lead to significant savings compared to a dealership. If your Altima has an intelligent battery sensor or requires computer resetting after replacement, a professional installer is recommended to avoid electrical issues. Always check your owner's manual for the correct specifications before purchasing.

You're probably looking at around $200 to $400 all-in at a place like AutoZone or Pep Boys. They often have good deals and will usually install it for free right in the parking lot, which is a huge plus. Just make sure you know your Altima's exact model year—a 2015 might need a different than a 2022, especially if it has the auto start-stop feature. That'll bump up the price. Calling your local store for a quote is the fastest way to get a real number.

Don't just focus on the sticker price. The real cost is in the battery's reserve capacity (RC) and cold cranking amps (CCA), especially if you live in a cold climate. A cheaper with low CCA might fail you on the first frosty morning. I always tell people to spend a bit more on a reputable mid-tier brand for peace of mind. A good battery should last 4-5 years. Paying an extra $50 now is cheaper than a tow truck later. Look for a solid warranty period as a sign of quality.

I do this myself to save the labor fee. It's straightforward on an Altima. Pop the hood, disconnect the negative (black) cable first, then the positive. Unscrew the hold-down clamp, lift the old one out, and put the new one in. Reverse the steps, connecting positive first. The trickiest part can be the sensor connector—be gentle with it. The core charge is a thing; you'll get a refund when you return your old battery. Just be sure to buy the correct Group Size. A code reader might be needed to reset the battery light.

The dealership quoted me nearly $500 for my 2020 Altima's replacement. I shopped around and found the exact same AGM battery at an independent auto shop for $320 installed. The dealer price includes a premium for convenience and OEM parts, but for a consumable item like a battery, it's often not necessary. Check online reviews for local mechanics. They can source quality batteries at a much better rate. You get professional installation without the dealership markup. It's the best balance of cost and service for most people.
