In Hyundai’s gasoline and diesel cars, the conventional 12‑volt battery is typically housed in the engine bay, usually on the driver’s side. In hybrids, the 12‑volt battery is usually in the engine bay as well, while the high‑voltage traction battery sits under the rear floor; in fully electric Hyundai models, the high‑voltage battery is mounted under the floor and the 12‑volt auxiliary battery often resides in the front trunk or behind a service panel. Exact placement can vary by model year and region, so verify with the owner’s manual or a Hyundai dealer for your specific vehicle.
Battery layouts by vehicle type
These sections describe the typical placements you’re likely to encounter, with caveats for year-to-year changes and regional variations.
Gasoline and diesel models
For traditional internal combustion engine (ICE) Hyundais, the 12‑volt battery is usually located in the engine bay. It’s commonly found on the driver’s side near the fender for easy access during maintenance.
- 12‑volt battery located in the engine bay, typically toward the driver’s side fender.
- Access is usually through the hood; service panels may cover the battery in some trims.
As with any vehicle, battery access points and cover arrangements can vary by model year, so consult the owner’s manual or a dealer for exact location.
Hybrid models
Hyundai hybrids keep a 12‑volt battery in the engine bay in most configurations, but the high‑voltage traction battery is placed in a different location to optimize space and weight distribution.
- 12‑volt battery commonly in the engine bay (same general area as ICE models).
- High‑voltage traction battery sits under the rear floor or beneath the rear seats, depending on the model.
Be aware that access to the high‑voltage system requires special safety procedures and trained technicians.
Electric models
Fully electric Hyundai models carry a large high‑voltage battery pack and a separate 12‑volt auxiliary battery. The traction battery is typically mounted under the floor, while the 12‑volt battery location varies by model and year.
- Main high‑voltage battery (traction pack) mounted in a floor‑embedded position between the axles.
- 12‑volt auxiliary battery commonly located in the front trunk (frunk) or behind a service panel near the front bulkhead.
Because BEV layouts differ by model, always confirm the exact location in your owner’s manual or with a Hyundai technician.
How to locate the battery in your specific Hyundai
To pinpoint the exact battery location for your vehicle, start with the owner’s manual and use the index under Electrical System or Battery. Visually inspect the engine bay for a rectangular 12‑volt box or the frunk area in BEVs. If you’re unsure or planning maintenance, contact a Hyundai service center to avoid hazards associated with high‑voltage components.
Summary
Hyundai battery placement depends on drivetrain: ICE vehicles typically house the 12‑volt battery in the engine bay; hybrids keep a 12‑volt in the engine bay while the high‑voltage battery sits under the rear floor; electric models place the high‑voltage battery under the floor with the 12‑volt battery often in the front trunk or front bulkhead area. Always check the specific model year and region in the owner’s manual or with a dealer for exact location.
