AGM vs flooded — which does this vehicle need?

The 2015 Toyota Highlander came from the factory with a standard flooded lead-acid battery. This type of battery is reliable and affordable, making it a popular choice for many vehicles. However, if you live in a colder climate or use your Highlander for frequent short trips, an AGM (Absorbent Glass Mat) battery is a worthwhile upgrade. AGM batteries are more resistant to vibration, have a longer lifespan, and perform better in extreme temperatures. They are also spill-proof, making them a safer option. While an AGM battery is more expensive upfront, its longer life and superior performance can make it a better value in the long run.

Post-installation relearn / reset procedure

After replacing the battery in your 2015 Toyota Highlander, you may need to perform a simple relearn procedure to ensure all systems are functioning correctly. The most common issue is an erratic idle, which can be resolved by allowing the engine to idle for a few minutes. You may also need to reset the power windows and sunroof. To do this, simply roll each window down and hold the button for a few seconds, then roll it up and hold the button again. The sunroof can be reset in a similar manner. In most cases, these simple procedures are all that is needed to get your Highlander back to normal.

Signs of a failing battery

• Slow engine crank: If your Highlander takes longer than usual to start, it could be a sign of a weak battery.
• Dimming lights: A failing battery may not have enough power to run all the electrical components in your vehicle, causing the lights to dim when you start the engine or use accessories.
• Warning light: The battery light on your dashboard is a clear indication that there is a problem with the charging system or the battery itself.
• Corrosion: If you see a white, powdery substance on the battery terminals, it is a sign of corrosion, which can interfere with the flow of electricity.

Common battery issues for this generation

The third-generation Highlander (2014-2019) is a reliable vehicle, but it is not without its share of common issues. One of the most frequently reported problems is a parasitic draw, which can cause the battery to drain overnight. This can be caused by a faulty relay or a malfunctioning accessory. If you are experiencing this issue, it is important to have it diagnosed and repaired by a qualified technician to avoid premature battery failure.
