What batteries does Chevy use?
Chevrolet uses two main categories of batteries across its lineup: traditional 12‑volt starter batteries for most gasoline and hybrid models, and high‑voltage lithium‑ion packs for its electric and plug‑in vehicles. The company has anchored its EV strategy around GM’s Ultium platform, with LG Energy Solution as a key partner for many cells.
Two tiers of battery technology in Chevrolet's lineup
The following outlines the two broad families you’ll encounter in Chevrolets today: the conventional 12‑volt systems that power starting and electronics in non‑EVs, and the high‑voltage lithium‑ion packs used in Chevy’s electric and plug‑in models. The sections below summarize each category and indicate typical suppliers.
Chevrolet’s battery setup varies by model and generation, but the pattern is consistent across most current vehicles: traditional 12‑volt systems for internal combustion and hybrid models, and high‑voltage packs for electric powertrains.
- 12‑volt starter batteries are standard on most Chevrolet gasoline-powered vehicles. These are typically standard flooded 12‑V units, with some models opting for AGM (absorbed glass mat) versions to support start‑stop systems and greater electrical demand.
- In certain trims or configurations, Chevrolet may specify AGM or higher‑capacity 12‑V batteries to support more demanding electrical loads or advanced features.
In short, Chevy continues to rely on conventional 12‑volt batteries for the vast majority of its non‑electric models, with variations by model/year.
High‑voltage lithium‑ion and Ultium packs
For electric and plug‑in vehicles, Chevrolet’s strategy centers on two overlapping families of high‑voltage packs: the Bolt’s lithium‑ion packs and the larger Ultium battery system used by the broader lineup of EVs. The Ultium system is produced through Ultium Cells LLC, a joint venture between General Motors and LG Energy Solution, and is characterized by large-format pouch cells designed to scale across vehicles.
Bolt EV and Bolt EUV
The Bolt family uses lithium‑ion battery packs supplied by LG Energy Solution (formerly LG Chem). These high‑voltage packs are mounted in the vehicle floor and power the Bolt’s all‑electric drive. The Bolt has historically been positioned as a compact‑to‑midsize EV with a focus on affordability and practicality. There was a notable recall period tied to LG‑made battery modules in the early years of the Bolt, prompting replacements and updates to address fire‑risk concerns.
In summary, Bolt models rely on LG Energy Solution lithium‑ion cells for their high‑voltage packs, with the platform designed to deliver practical range for everyday use.
Ultium‑based Chevrolet EVs (Blazer, Equinox, Silverado, and more)
Chevrolet’s newer electric models—such as the Blazer EV, Equinox EV, and Silverado EV—run on GM’s Ultium battery system. Ultium Cells LLC manufactures these cells in collaboration with LG Energy Solution, using a nickel‑rich, cobalt‑reduced chemistry housed in large-format pouch cells. The modular design allows GM to tailor pack capacity and vehicle range across different models and trims, from smaller crossovers to full‑size pickup trucks.
In practice, Ultium batteries enable longer-range and faster‑charging capabilities across Chevrolet’s expanding EV lineup, while offering scalable options for diverse vehicle segments.
Summary
Chevrolet’s battery strategy encompasses two distinct approaches. For traditional internal combustion and many hybrids, the company relies on conventional 12‑volt lead‑acid batteries (with possible AGM variants) to power starting and electronics. For electric and plug‑in models, Chevy uses lithium‑ion high‑voltage packs: Bolt vehicles use lithium‑ion packs supplied by LG Energy Solution, while the broader Ultium‑based lineup (Blazer EV, Equinox EV, Silverado EV) uses Ultium battery cells produced by Ultium Cells LLC in collaboration with LG Energy Solution, featuring nickel‑rich chemistry with reduced cobalt and a modular, scalable design. Historically, Bolt models also faced battery-related recalls that led to module replacements, underscoring ongoing attention to safety and reliability in the early EV era. As Chevrolet continues to electrify its lineup, Ultium remains central to its long‑range EV strategy.
What kind of battery is in a Chevy Silverado?
Choosing the Right Battery for Your Chevy Silverado 1500
To maintain maximum reliability and efficiency, the Silverado 1500 is typically compatible with Group 48 (H6) and Group 94R (H7) batteries.
Who is the battery supplier for GM?
GM batteries are made by Ultium Cells LLC, a joint venture between General Motors and LG Energy Solution. This venture operates manufacturing plants in Ohio, Tennessee, and Michigan to produce large-format battery cells for GM's electric vehicles. GM also has a partnership with Samsung SDI to diversify its battery production and a deal with Redwood Materials for energy storage batteries.
Ultium Cells LLC
- This is the primary joint venture between General Motors and LG Energy Solution for producing EV battery cells.
- It operates plants in locations such as Warren, Ohio; Spring Hill, Tennessee; and Lansing, Michigan.
- The facilities use advanced Nickel Cobalt Manganese Aluminum (NCMA) chemistry to create high-performance battery cells.
Other partnerships
- Samsung SDI: In 2023, GM announced a joint venture with Samsung SDI to develop and manufacture battery cells, diversifying its cell formats and production sources.
- Redwood Materials: GM has a partnership with Redwood Materials to pursue the use of U.S.-built batteries for energy storage systems.
- Forge Nano: GM has invested in Forge Nano, which uses its proprietary technology to improve the performance and lifespan of batteries for GM's EVs.
What brand of battery does Chevy use?
Chevrolet vehicles can use a variety of batteries, such as the ACDelco brand recommended by Chevrolet, or other common battery types like AGM or flooded batteries, with the specific type and size depending on the model and year. To find the exact battery for your car, check your owner's manual or look at the existing battery for its size and group number, which are often designated like Group 48 (H6) or Group 94R (H7) for models like the Silverado.
How to find the right battery for your Chevy
- Check your owner's manual: This is the most reliable way to determine the correct battery specifications for your vehicle.
- Inspect the current battery: Look for the BCI group size (e.g., 48, 94R, 34/78) and other specifications on the battery itself. This will give you a direct replacement size, says Cornerstone Chevrolet.
- Consult a parts store: Major auto parts retailers like AutoZone and Walmart have online tools where you can enter your vehicle's make, model, and year to find compatible batteries.
- Understand battery specifications: Pay attention to important details like Cold Cranking Amps (CCA) for starting in cold weather, and Reserve Capacity (RC), which indicates how long the battery can power accessories if the alternator fails, notes East Hills Chevrolet of Roslyn.
Common battery types for Chevy
- ACDelco: This is a brand strongly recommended by Chevrolet and is a common choice for replacement batteries, explains Chevrolet and this YouTube video.
- AGM (Absorbent Glass Mat): These are a premium option, often chosen for better performance in extreme temperatures and for vehicles with a lot of electronics. They are common in many modern vehicles, including some Chevrolet models.
- Flooded: This is the more traditional and typically more budget-friendly option.
Does Chevy use AGM batteries?
These vehicles (model years 2018 to present) likely need an AGM battery: Ford F-150. Dodge Durango. Chevrolet Cruze.
