AGM vs. flooded — which does this vehicle need?
The 2017 Honda Civic originally came equipped with a standard flooded lead-acid battery. This type of battery is perfectly suitable for the vehicle's electrical demands and is generally the most cost-effective option. However, upgrading to an Absorbed Glass Mat (AGM) battery is a popular choice for many owners.
AGM batteries offer several advantages:
- Maintenance-free: No need to check electrolyte levels or add distilled water.
- Vibration resistance: More resistant to vibration, which can prolong battery life.
- Longer lifespan: Often have a longer overall lifespan than flooded batteries.
- Deeper discharge cycles: Better suited for vehicles with high electrical demands or start-stop systems (though the 2017 Civic does not typically have start-stop).
- Leak-proof: The electrolyte is absorbed into glass mats, preventing leaks even if the casing is damaged.
While an AGM battery is an excellent upgrade, it's not strictly
