AGM vs flooded — which does this vehicle need?

The 2019 Nissan Frontier comes from the factory with a standard flooded lead-acid battery. This is a reliable and cost-effective option that will serve most owners well. However, an Absorbed Glass Mat (AGM) battery is a worthwhile upgrade for many drivers.

AGM batteries are more resistant to vibration, which is a significant advantage on a truck that may see rough roads or off-road use. They are also fully sealed, meaning they won't leak acid and are maintenance-free. AGM batteries typically have a longer lifespan and are better at handling the deep-cycling demands of modern vehicles with many electronic accessories. If you frequently use your Frontier for activities like winching, running auxiliary lights, or listening to the stereo with the engine off, an AGM battery is a smart choice.

Post-installation relearn / reset procedure

Fortunately, the 2019 Nissan Frontier does not require a complex relearn procedure after the battery is disconnected. The main thing you will need to do is reset your radio presets and clock. Your vehicle's engine and emission control systems will automatically recalibrate as you drive.

Signs of a failing battery

• Slow engine crank: This is the most common sign of a weak battery. The engine will turn over more slowly than usual, especially in cold weather.
• Dimming lights: If your headlights and interior lights dim when you start the engine, it's a sign the battery is struggling to provide enough power.
• Warning light: The battery light on your dashboard may illuminate if the charging system is not working correctly, which can be a sign of a failing battery or alternator.
• Corrosion on terminals: A white, powdery substance around the battery terminals is a sign of corrosion, which can interfere with the flow of electricity.
• Old age: Most car batteries have a lifespan of 3-5 years. If your battery is older than that, it's a good idea to have it tested, even if you haven't noticed any problems.

Common battery issues for this generation

The most common battery issue for the 2019 Nissan Frontier is simply old age. As the battery gets older, it loses its ability to hold a charge. This is a normal process, but it can be accelerated by factors like extreme temperatures and frequent short trips. Another issue to be aware of is the possibility of a parasitic draw. This is when an electrical component in the vehicle continues to draw power even when the engine is off, which can drain the battery overnight. If you are experiencing frequent dead batteries, it's a good idea to have your vehicle checked for a parasitic draw.
