2020 Nissan Frontier Battery: Group Size, CCA & Replacements

Quick answer: 2020 Nissan Frontier Battery Specs

For the 2020 model year, Nissan equipped all Frontier trucks with a new 3.8L V6 engine. This single engine option simplifies battery selection. Here are the specifications you need:

• BCI Group Size: Group 35
• Cold Cranking Amps (CCA): The original equipment (OEM) battery has around 650 CCA, but we recommend choosing a replacement with at least 700 CCA for reliable starting power in all climates.
• Reserve Capacity (RC): Aim for a battery with a reserve capacity of 100 minutes or more.
• Battery Type: A standard flooded lead-acid battery is what the vehicle came with from the factory. An Absorbent Glass Mat (AGM) battery is an optional upgrade but is not required.
• Terminal Layout: Left-hand positive terminal (when viewing the battery from the front, with terminals closest to you).
• Physical Dimensions (approximate):
  • Length: 9 1/16 inches (230 mm)
  • Width: 6 7/8 inches (175 mm)
  • Height: 8 7/8 inches (225 mm)
• Dual-Battery Setup: Not applicable. The Nissan Frontier does not have a diesel option and uses a single battery configuration.

Replacement Battery Options

When your factory battery wears out, several high-quality replacements are available that will meet or exceed OEM specifications. A Group 35 battery is one of the most common sizes in North America, so you will have plenty of options.

Here are 3 popular and reliable choices for your 2020 Frontier:

1. Interstate MTP-35 (Flooded): A direct, no-fuss replacement that offers excellent reliability and a strong warranty. For an upgrade, consider the Interstate MTZ-35 AGM battery, which provides longer life and better performance.
2. Optima YellowTop D35 (AGM): The YellowTop is a premium AGM battery known for its exceptional vibration resistance and deep-cycling capability, making it a great choice if you run accessories like off-road lights or a winch.
3. DieHard Platinum AGM 35: Sold by Advance Auto Parts, this is a highly-rated AGM battery that provides excellent starting power in extreme temperatures and has a long service life. It's a direct-fit replacement.

AGM vs. Flooded — Which Does This Vehicle Need?

The 2020 Nissan Frontier does not require an AGM battery. It was designed to use a traditional flooded lead-acid battery, and the truck's charging system is optimized for it. A quality flooded battery is perfectly sufficient and is the most cost-effective solution.

However, an AGM battery is a worthwhile upgrade, especially for a truck that may see rougher use. The key benefits of an AGM include:

• Vibration Resistance: The glass mat construction holds the lead plates securely, making AGMs far more durable on bumpy roads or off-road trails.
• Longer Lifespan: AGMs typically last longer than their flooded counterparts.
• Spill-Proof & Maintenance-Free: AGMs are sealed, meaning they won't leak acid and never require you to check or top-off distilled water.
• Better Performance: They offer more reliable power in extreme cold and heat and can handle the demands of modern vehicle electronics more effectively.

If your budget allows, upgrading to a Group 35 AGM battery is a smart investment in durability and peace of mind.

Post-Installation Relearn / Reset Procedure

Unlike many newer vehicles, the 2020 Frontier does not require a complex scan tool procedure to "register" a new battery with the vehicle's computer. The process is straightforward and can be done in your driveway.

1. Swap the Battery: After disconnecting the negative terminal first, followed by the positive, remove the old battery and install the new one. Secure the hold-down bracket.
2. Connect Terminals: Connect the positive terminal first, then the negative terminal. Ensure both are tight and free of corrosion.
3. Reset Basic Systems: You will lose your radio presets and clock settings. Simply reset them manually.
4. Reset Auto-Up Window: The driver's side auto-up window function may need to be reset. To do this, roll the window all the way down. Then, pull the switch up to roll the window completely closed and continue holding the switch in the "up" position for 3-5 seconds. The function should now be restored.
5. Idle the Engine: Start the truck and let it idle in Park for about 10 minutes. This allows the engine control unit (ECU) to relearn fuel trims and idle parameters.

Signs of a Failing Battery

• Slow Engine Crank: The engine turns over sluggishly when you turn the key.
• Clicking Noise: A rapid clicking sound when trying to start indicates the battery doesn't have enough power to engage the starter motor.
• Dimming Lights: Headlights and interior lights may dim, especially upon startup.
• Warning Lights: A battery or check engine light may illuminate on your dashboard.
• Swollen Case: If the sides of the battery are bulging, it's a sign of internal damage and it should be replaced immediately.

Common Battery Issues for This Generation

The D40 platform Frontier is a robust and relatively simple truck. Battery issues are typically a result of normal aging, climate, and usage patterns. A common issue to be aware of is parasitic draw from accessories left plugged into 12V power outlets, which can drain the battery if the truck is left sitting for long periods. Additionally, consistent short-distance driving may not allow the alternator enough time to fully recharge the battery, potentially shortening its lifespan.
