Scope note

US-market model years 2022 through 2026, each from the Owner's Handbook & Warranty Information that Hyundai's warranty page links for that year; EPA rates the Tucson Plug-in Hybrid for each of those years. Hyundai writes one handbook per model year for its whole US lineup, and the rows above are the terms each handbook gives the Plug-in Hybrid Battery and the High Voltage Battery. The handbook delivered with a specific car is the authority for that car.
