The vehicle uses two complementary systems: a high-voltage hybrid battery pack for electric propulsion and a 12V auxiliary battery for accessories and control modules.
Hybrid packs use manufacturer-specified advanced battery chemistry and construction designed for durability and energy density; the exact chemistry and configuration are OEM-specific.
The 12V auxiliary battery in many Hyundai hybrids is often an absorbed glass mat (AGM) or enhanced lead-acid design depending on equipment; the dealership will confirm the OEM spec for your car.
Courtsey Hyundai of Tampa uses OEM parts and calibration procedures to ensure the correct battery type and chemistry are installed for safe, efficient operation.
Warranty-covered battery work must be performed at a certified dealership to ensure correct parts, installation, and warranty compliance.

What size battery is in the 2023 Hyundai Sonata Hybrid?

Battery size for the high-voltage pack is specified by the manufacturer and expressed in kWh; the exact capacity and configuration vary by vehicle options and production specifications.
The 12V battery uses a vehicle-specific group size and cold cranking/CCA rating; fitment depends on the factory configuration and option package.
Courtesy Hyundai of Tampa verifies the precise OEM battery group number and high-voltage pack specifications for each vehicle to ensure proper fitment and performance.
Using the correct OEM size and rating prevents electrical issues, ensures warranty coverage, and optimizes longevity and safety—important reasons to choose dealership service.
