2018 Hyundai Ioniq Plug-In Hybrid Battery Type

The 2018 Hyundai Ioniq Plug-In Hybrid uses two primary battery systems: a conventional 12V battery for accessory power and a higher-voltage rechargeable pack for propulsion and electric driving. The traction battery uses chemistry designed for repeated deep cycles and efficient energy recovery; the 12V system uses a different construction focused on cold-start and accessory support. Knowing the difference matters when choosing replacement parts: the wrong chemistry or a non-certified unit can reduce range, charging efficiency, and long-term reliability. At Arapahoe Hyundai our technicians match replacements to factory specifications, test performance under load, and verify charging system health. We communicate warranty coverage and recommend the OEM or certified remanufactured components when appropriate.
