What battery brand does Chevy use?
Chevrolet uses different battery brands depending on the vehicle type: ACDelco batteries are standard for most gas-powered Chevrolets, while its electric vehicles rely on GM’s Ultium battery technology, built in partnership with LG Energy Solution.
Chevrolet's conventional lineup: battery choices for gas and hybrid models
The following overview explains the battery brands Chevy uses in its conventional (gasoline and hybrid) lineup.
- ACDelco Original Equipment (OE) batteries are the standard choice for most Chevrolet models as the OEM replacement.
- ACDelco Gold, Silver, and Professional lines provide varying levels of performance, price, and warranty, with AGM (absorbed glass mat) and EFB (enhanced flooded) variants available for features like start-stop systems.
- GM dealerships and service centers commonly stock ACDelco batteries for routine maintenance and replacements.
In short, for conventional Chevrolets, the battery brand you’ll encounter most often is ACDelco, with product lines tailored to different needs and vehicle equipment.
Electric-vehicle batteries: Ultium technology
Chevrolet’s electric vehicles rely on Ultium battery technology. The cells are produced by Ultium Cells LLC, a joint venture between General Motors and LG Energy Solution, and are packaged into Ultium battery packs assembled by GM for use in EV models.
What makes Ultium batteries distinct
The Ultium backbone features cells designed for high energy density and flexibility, assembled into modular packs that can support different voltage architectures. This platform is intended to underpin a broad range of GM vehicles, including Chevrolet’s current and upcoming electric models.
- Cells and packs: Ultium cells (supplied by LG, assembled into GM-pack configurations by Ultium Cells LLC and GM facilities).
- Chemistry and design: Nickel-rich, low-cobalt chemistry with aluminum components to balance energy density and affordability.
- Vehicle applications: Used in models such as Bolt EV, Bolt EUV (older and newer generations), Blazer EV, Equinox EV, Silverado EV, and other forthcoming Chevrolet EVs.
In short, Chevrolet EVs use Ultium-branded battery technology, with cells sourced through the GM-LG joint venture and packs built for the brand’s electric lineup.
What this means for Chevrolet owners
For non‑EV Chevrolets, expect ACDelco batteries as the OEM choice for replacements and service. For EV owners, the battery system is built around Ultium technology, with support and warranties administered through GM and its authorized service network.
- Warranty and service: EV battery packs are covered under GM’s separate EV warranty terms; consult your vehicle’s warranty documentation for specifics.
- Maintenance: Regular battery health checks and proper charging practices are handled through GM-certified service centers, which source components as appropriate (ACDelco for conventional models; Ultium components for EVs).
These arrangements reflect Chevrolet’s approach to reliability and standardization across its broad vehicle lineup, balancing traditional battery technology with next‑generation power packs for its electric future.
Summary
Chevrolet primarily uses ACDelco batteries for its gasoline and hybrid vehicles, while its electric lineup relies on Ultium battery technology produced via the GM-LG Ultium Cells JV. EVs employ Ultium packs that support flexible charging architectures, with cells supplied by LG Energy Solution and assembled in GM facilities. This dual approach covers the majority of Chevrolet’s current and planned models, from Spark and Malibu to Bolt, Blazer, and Silverado EV.
