In short: Chevy relies on ACDelco for most traditional 12-volt batteries, while its electric vehicles use Ultium battery packs built in partnership with LG Energy Solution. This means the brand varies by the part of the system you’re examining—the conventional 12-volt battery versus the high-voltage EV pack.
Low-voltage batteries: the standard 12-volt units
What this means for Chevy owners
Most Chevy models—gasoline and hybrids alike—use a 12-volt lead-acid battery sourced by ACDelco, GM’s factory brand. The 12-volt battery powers accessories, stabilizes electrical systems, and starts the engine or hybrid system.
- ACDelco is Chevrolet/GM’s official 12-volt battery supplier for the bulk of its vehicles.
- 12-volt units are typically lead-acid; some higher trim levels use AGM (absorbed glass mat) designs for improved performance and longevity.
- When replacing, many dealers and aftermarket retailers stock ACDelco Gold/Gold-Plus or Silver lines that fit Chevrolet models.
Before listing the typical brands you’ll encounter, note that the majority of Chevy vehicles use ACDelco as the official 12-volt battery supplier.
This branding approach helps ensure compatibility, warranty support, and consistent performance across Chevy’s lineup.
Electric vehicles and high-voltage packs
Battery-origin details for EVs
The high-voltage propulsion batteries in Chevrolets are built on GM’s Ultium platform. The cells are supplied by LG Energy Solution and assembled into modules by Ultium Cells LLC, a GM-LG joint venture. This architecture underpins Chevy’s current and upcoming EVs, including Bolt-based models and newer Ultium-based crossovers.
- High-voltage packs in Chevy EVs use Ultium battery technology designed for long-range and modular scalability.
- The battery cells come from LG Energy Solution and are integrated into packs by Ultium Cells LLC (a GM-LG venture).
- The Ultium platform is intended for multiple GM brands, allowing Chevrolet to share core technology across its electric lineup.
Before listing the key details about high-voltage packs, here is the EV-specific branding landscape.
In practice, Chevy’s EVs do not rely on a single consumer-branded "Chevy battery" label in the way traditional 12-volt batteries do; instead, they use Ultium battery packs built through a collaboration with LG Energy Solution.
Summary
Chevrolet uses ACDelco for typical 12-volt batteries and Ultium battery packs for its electric vehicles, with the cells supplied by LG Energy Solution and assembled by Ultium Cells LLC. This dual-approach reflects GM’s strategy to standardize conventional electrical systems while advancing high-voltage EV technology.
Who makes batteries for GM?
GM manufactures Ultium batteries at facilities in Ohio, Tennessee, and Michigan, with plans for additional plants in partnership with Samsung SDI.
Which battery is better, ACDelco or Duralast?
It's honestly a tie. Both brands have excellent high-performance models that meet or exceed OE specs. If you're in a cold climate, check the CCA rating of the individual battery you're considering, but both brands offer cold-start-ready options.
