Ni‑MH Hybrid Battery Pack for Toyota RAV4 Hybrid (Including PHEV) 1st Generation (2015–2022)

 Product Overview

The Ni‑MH Hybrid Battery is a high‑performance, OEM‑compatible traction battery engineered exclusively for the 1st Generation Toyota RAV4 Hybrid (2015–2022) (XA40/XA50), covering both Hybrid (HEV) and Plug‑in Hybrid (PHEV) variants. Built with premium prismatic nickel‑metal hydride cells, a robust air‑cooled thermal management system, and precise electronic calibration, this battery serves as the heart of Toyota’s Hybrid Synergy Drive (HSD) system. It delivers stable high‑power output, efficient energy recovery via regenerative braking, and seamless integration with the RAV4’s hybrid control unit. Designed as a direct replacement, it restores original fuel efficiency, electric assist performance, and overall hybrid system reliability for aging RAV4 Hybrid and PHEV models.
