Most 12‑volt batteries last about 3–5 years, with hot, humid Florida conditions often pushing lifespan toward the lower end.

For the 2018 Toyota Highlander Hybrid driven around Jacksonville and Northeast Florida, heat accelerates internal battery wear.

We provide quick diagnostics and replacement using OEM‑spec parts.
