The 2025 Jeep Wagoneer S uses two primary battery systems: a high‑voltage traction battery for propulsion and a low‑voltage 12‑volt battery for accessories and control modules. Battery chemistries differ by system—traction batteries rely on advanced cells optimized for energy density and thermal management, while 12‑volt batteries focus on reliable cold‑cranking and accessory support. At Larry H. Miller Colorado Jeep our technicians identify the correct chemistry and sizing, and they install only compatible OEM replacements to preserve vehicle systems and warranties. We also highlight promotions and loyalty opportunities—check our
service specials and ask about fleet or repeat‑customer benefits. Whether you need a routine 12‑volt swap or a thorough traction battery inspection, our team will explain options, recommend the best path forward, and help you
