AGM vs. Flooded — Which Does This Vehicle Need?
The 2019 Toyota Highlander rolled off the assembly line equipped with a standard flooded lead-acid battery. This type of battery is perfectly adequate for the vehicle's electrical demands under normal circumstances. Flooded batteries are generally more affordable and have been the industry standard for decades.
However, an Absorbent Glass Mat (AGM) battery is an excellent upgrade for your Highlander. AGM batteries offer several advantages:
- Vibration Resistance: The glass mat construction helps them withstand vibrations better than flooded batteries, which can be beneficial for longevity.
- Slower Self-Discharge: They lose their charge more slowly when stored, making them a good choice if your Highlander isn't driven daily.
- Maintenance-Free: AGM batteries are sealed and do not require water top-offs.
- Improved Performance: They often provide higher CCA ratings and better resistance to deep cycling, which can be beneficial for vehicles with more demanding electrical accessories or for those who frequently drive short distances.
- Leak-Proof: If the battery case cracks, an AGM battery is less likely to leak corrosive acid.
While an AGM battery isn't strictly "needed" for the 2019 Highlander, it
