Most automotive batteries last 3–5 years, and in St. Augustine's heat and humidity you should expect life toward the lower end (about 3 years).

Coastal driving, frequent short trips and hot, humid conditions around Saint Augustine accelerate battery wear for the 2021 Honda Clarity. Regular charging and annual checks can help catch decline early. If you drive mostly short commutes or park outdoors, plan on testing the battery more often.
