AGM vs flooded — which does this vehicle need?

The 2018 Nissan Frontier comes equipped from the factory with a standard flooded lead-acid battery. This type of battery is perfectly suitable for the vehicle's electrical demands and is generally more affordable. However, an Absorbent Glass Mat (AGM) battery is a popular and compatible upgrade.

AGM batteries offer several advantages:

• Longer lifespan: They tend to last longer than traditional flooded batteries.
• Greater vibration resistance: Ideal for off-road enthusiasts or those who frequently drive on rough roads.
• Slower self-discharge rate: Holds a charge better when the vehicle is not in use.
• Maintenance-free: No need to check electrolyte levels.
• Spill-proof design: Safer in the event of an accident.

While an AGM battery offers superior performance, it's not strictly necessary. If you primarily use your Frontier for daily commuting and don't live in extreme climates, a high-quality flooded battery will serve you well. If you frequently use accessories, live in harsh environments, or seek maximum reliability, an AGM is a worthwhile investment.

Post-installation relearn / reset procedure

After replacing the battery in your 2018 Nissan Frontier, it's common to experience some minor issues like rough idling, elevated idle speed, or the radio asking for a code. These are usually temporary and can often be resolved with a simple idle air volume relearn procedure.

Important Safety Note: Always disconnect the negative battery terminal first and reconnect it last to prevent accidental shorts.

Here's a common procedure for an idle relearn:

1. Warm up the engine: Drive the vehicle until it reaches normal operating temperature.
2. Turn off the engine and wait: Turn off the engine and wait at least 10 seconds.
3. Perform accelerator pedal release position learning:
   • Turn the ignition switch to the ON position (engine off).
   • Wait 3 seconds.
   • With the ignition ON, fully depress and release the accelerator pedal 5 times within 5 seconds.
   • Wait 7 seconds.
   • Fully depress the accelerator pedal and keep it depressed for approximately 20 seconds until the Check Engine Light (Service Engine Soon light) stops blinking and stays ON.
   • Release the accelerator pedal.
   • Start the engine and let it idle for at least 30 seconds. Ensure no accessories are running.
   • If the idle is still rough, repeat the procedure.

Radio Code: If your radio requires a code, consult your owner's manual or contact a Nissan dealership with your VIN to retrieve it.

Signs of a failing battery

Keeping an eye out for these signs can help you replace your battery before you're stranded:

• Slow cranking: The engine cranks slower than usual when you try to start it.
• Dim lights: Headlights and interior lights appear dim, especially when the engine is off.
• Warning lights: A battery warning light or "check engine" light may illuminate on your dashboard.
• Corrosion: White or blue powdery substance around the battery terminals.
• Swelling battery case: The battery case appears swollen or bloated, which can indicate internal damage.
• Foul odor: A sulfur or rotten egg smell coming from the battery can indicate a leak or internal short.
• Age: Automotive batteries typically last 3-5 years, depending on climate and usage.

Common battery issues for this generation

Owners of the 2018 Nissan Frontier generally report reliable battery performance. However, like any vehicle, some common issues can arise:

• Parasitic drain: Aftermarket accessories or sometimes even factory components can draw power when the vehicle is off, leading to a dead battery over time. If your battery repeatedly dies even after a full charge, a parasitic drain test may be necessary.
• Alternator issues: A failing alternator won't properly charge the battery, leading to repeated battery failures. If your battery light is on or you consistently have starting trouble, have your alternator tested.
• Terminal corrosion: While common in all vehicles, neglected battery terminals can lead to poor electrical connections and starting problems. Regular cleaning of the terminals can prevent this.
