AGM vs flooded — which does this vehicle need?
The 2020 Toyota RAV4, especially models equipped with start-stop technology, is best served by an Absorbent Glass Mat (AGM) battery. While a standard flooded lead-acid battery might fit and function initially, it will likely have a significantly shorter lifespan and may not adequately support the vehicle's complex electronics and power demands. AGM batteries offer better deep-cycle resistance, faster recharging, and are more resilient to the frequent start-stop cycles that are common in modern vehicles. They are also spill-proof and more resistant to vibration, making them a safer and more durable choice.
Post-installation relearn / reset procedure
Fortunately, the 2020 Toyota RAV4 typically does not require a complex relearn or reset procedure after a battery replacement. However, you may notice that the idle is a bit rough for the first few miles as the engine control unit (ECU) relearns the fuel trims. It is also a good idea to check and reset your clock and radio presets. In some cases, the power windows may need to be re-initialized by running them all the way down and then all the way up.
Signs of a failing battery
- Slow engine crank: The engine turns over more slowly than usual when you try to start it.
- Dimming lights: The headlights and interior lights dim when the engine is off or at idle.
- Warning lights: A battery or charging system warning light appears on the dashboard.
- Swollen or leaking battery case: The battery case appears bloated or is leaking fluid.
- Corrosion on the terminals: A white, powdery substance is visible on the battery terminals.
Common battery issues for this generation
The fifth-generation RAV4 is generally reliable, but some owners have reported premature battery failure. This can be exacerbated by short driving trips where the battery does not have sufficient time to fully recharge. The increased electrical load from modern features like large infotainment screens, numerous sensors, and start-stop systems can also put a strain on the battery. Using an AGM battery and ensuring it is properly secured can help mitigate these issues.
