What type of battery is in the 2012 Hyundai Sonata Hybrid?

  • The 2012 Hyundai Sonata Hybrid uses a high-voltage hybrid battery pack; vehicles of this model year commonly use a nickel-metal hydride (NiMH) chemistry designed for hybrid energy storage.
  • Options when replacing include new OEM NiMH packs, manufacturer-approved remanufactured modules, and select aftermarket alternatives—each with different warranties and life expectations.
  • Our factory-trained technicians will confirm the exact chemistry and configuration for your vehicle using VIN and on-vehicle diagnostics before recommending replacement options.
  • Choosing dealership installation ensures compatibility, correct module programming, and retention of any remaining manufacturer-related coverage.

What size battery is in the 2012 Hyundai Sonata Hybrid?

  • Hybrid battery capacity is expressed by voltage and pack design rather than traditional cold-cranking amps; the 2012 Sonata Hybrid typically uses a high-voltage pack in the neighborhood of 200–300 volts (commonly around 270V) tailored to the hybrid system.
  • Physical dimensions and exact voltage/capacity specs can vary by production batch and market; we verify the precise pack specifications during inspection to recommend the correct replacement.

2012 Hyundai Sonata Hybrid Battery Size

Battery size for a 2012 Hyundai Sonata Hybrid refers primarily to the pack’s electrical specifications—voltage and usable capacity—and the physical pack design that fits the vehicle. Typical high-voltage hybrid packs for this model year are in the range of a couple hundred volts (commonly around 270V) and are configured to meet the Sonata Hybrid’s power and energy needs. Routine battery checks measure parameters like voltage consistency, cell health, and state-of-charge behavior, so our technicians can determine if cell replacement, module refurbishment, or a full pack swap is needed. At Courtesy Hyundai of Tampa we verify exact pack dimensions and electrical ratings before ordering parts, avoiding improper fitment and ensuring the replaced unit matches factory tolerances.
