Replacement Battery Options

Here are some popular replacement battery options for your 2017 Nissan Altima. Always verify fitment and specifications with the retailer.

• Interstate: MT-24F
• Optima: Optima RedTop 35 (requires adapter/spacer kit for proper fitment, as it's a Group 35 and slightly smaller than 24F)
• DieHard: DieHard Gold 24F
• Odyssey: Odyssey 34-780 (group 34/78, slightly different dimensions, may require minor tray modification or specific fitment kit)
• ACDelco: ACDelco Advantage 24F

AGM vs. Flooded — Which Does This Vehicle Need?

Your 2017 Nissan Altima originally came equipped with a standard flooded lead-acid battery. This type of battery is perfectly suitable and cost-effective for the vehicle's electrical demands. However, an Absorbed Glass Mat (AGM) battery is a popular and recommended upgrade for several reasons.

AGM batteries offer several advantages over traditional flooded batteries:

• Longer Lifespan: Generally, AGM batteries last longer due to their design, which better resists vibration and sulfation.
• Improved Performance: They often provide stronger starting power and maintain voltage more consistently, especially in demanding conditions.
• Maintenance-Free: AGM batteries are sealed and do not require water top-offs.
• Leak-Proof: The electrolyte is absorbed in glass mats, preventing spills and making them safer.

While an AGM battery is not required for your 2017 Altima, it is a worthwhile investment if you're looking for enhanced reliability, performance, and longevity, particularly if you live in extreme climates or have aftermarket electrical accessories.

Post-Installation Relearn / Reset Procedure

After disconnecting and replacing the battery in your 2017 Nissan Altima, you may notice some temporary issues or warning lights. Most of these will resolve themselves after a short driving period, but some require a simple reset or relearn procedure.

Here's a general guide:

1. Idle Relearn: The engine's idle speed may be erratic or high immediately after battery replacement. Drive the vehicle for 10-15 minutes, allowing the engine to reach operating temperature and the vehicle's computer (ECU) to re-learn its idle parameters. You can also try starting the car, letting it idle for 5 minutes, turning on the AC for 5 minutes, and then turning on the headlights for 5 minutes.
2. Power Window Auto Up/Down: The "auto" up/down function for the power windows may not work. To reset:
   • Close the window completely.
   • Press and hold the window switch up for several seconds after the window is closed.
   • Open the window completely.
   • Press and hold the window switch down for several seconds after the window is fully open.
   • Repeat for each window.
3. Radio Presets & Clock: These will need to be reprogrammed manually.
4. Tire Pressure Monitoring System (TPMS): The TPMS light may illuminate initially. Drive the vehicle at speeds above 15-20 mph for a few miles, and the system should re-calibrate. If it remains on, check tire pressures and, if necessary, have a professional reset it.
5. Steering Angle Sensor: In some cases, a Vehicle Dynamic Control (VDC) or ABS light may appear. Driving straight for a short distance (e.g., 5-10 minutes) usually resolves this as the steering angle sensor re-calibrates.

If any warning lights persist after following these steps and driving the vehicle, it's advisable to have your vehicle inspected by a qualified technician.

Signs of a Failing Battery

Understanding the signs of a dying battery can save you from being stranded. Here are common indicators that your 2017 Nissan Altima's battery might be on its last legs:

• Slow Engine Crank: The most common sign. The engine turns over sluggishly, as if struggling to start.
• Dim Headlights or Interior Lights: Especially noticeable when the engine is off or during cranking.
• Warning Lights: A "Battery" or "Check Engine" light can sometimes indicate a charging system issue, which may include the battery.
• Corrosion on Terminals: White or blue powdery substance on the battery terminals can impede flow and indicate a failing battery or charging issues.
• Swollen or Bulging Battery Case: A sign of overheating or overcharging, and the battery should be replaced immediately.
• Sulfuric Smell: A "rotten egg" smell indicates a leaking or damaged battery.
• Clicking Sound: If you hear a rapid clicking sound when trying to start the car, it often means the battery doesn't have enough power to engage the starter motor.

Common Battery Issues for This Generation

The 2013-2018 Nissan Altima generation is generally reliable, but like all vehicles, specific battery-related considerations can arise:

• Parasitic Draws: Aftermarket accessories or sometimes even factory components that don't properly shut down can slowly drain the battery over time, leading to premature failure if the car sits for extended periods.
• Voltage Sensitivity: Modern vehicles like the 2017 Altima are highly dependent on stable voltage. A weak or dying battery can lead to various electrical gremlins, including issues with infotainment, power windows, or even transmission shifting anomalies.
• Original Equipment Battery Lifespan: OEM batteries typically last 3-5 years. If your Altima is still on its original battery and is approaching or exceeding this age, it's wise to have it tested proactively.
• Terminal Corrosion: While not unique to the Altima, ensuring clean and tight battery terminals is crucial for proper power delivery and charging performance.
