Powering America’s Vehicles for Over a Century

We bring General Motors’ legacy of engineering excellence to every battery we produce — trusted by professional mechanics, fleet operators, and drivers who demand proven reliability under the hood.

The Professionals We Serve

Our batteries power the vehicles that keep America moving — from the service bays where technicians trust our Professional series to deliver consistent cranking power, to the commercial fleets running cross-country routes where AGM technology means fewer roadside failures.

We serve the Silverado owner who needs a battery that can handle Minnesota winters and Texas summers in the same year. The Corvette enthusiast who wants the same quality GM specifies at the factory. The independent shop that stakes its reputation on parts that don’t come back.

Every automotive battery and truck battery we ship carries the same expectation: start the first time, every time, in any condition. That’s not marketing language — it’s the standard mechanics have held us to since our parent company began supplying original equipment to automakers in 1916.

A Century of Automotive Power Innovation

1916
General Motors establishes United Motors Service — the foundation that would become ACDelco — to supply original equipment parts to the automotive industry. Battery technology becomes a core engineering focus as electric starters replace hand cranks.
Mid-Century
We expand into the professional aftermarket, supplying service centers and dealerships with batteries engineered to match OE specifications. The focus shifts from simply starting vehicles to powering increasingly complex electrical systems.
1980s–1990s
Our Professional series launches to meet the demands of technicians who need predictable performance across every vehicle platform — from compact cars to full-size trucks. Group sizing standardization makes battery replacement more efficient in high-volume shops.
2000s
We introduce AGM battery technology to handle the power demands of modern vehicles — supporting start-stop systems, advanced electronics, and higher parasitic loads without compromising cranking performance or cycle life.
Today
Our lineup spans Professional AGM, Professional Gold flooded batteries, and Gold series consumer options — all engineered to deliver the reliability GM has built its reputation on. We supply batteries for everything from classic Camaros to current-generation Silverados.

What Drives Our Engineering

Professional-Grade Standards

Every battery we ship meets the same specifications technicians expect from original equipment — consistent cold cranking amps, reliable reserve capacity, and dimensional accuracy that eliminates installation issues. We don’t build consumer batteries and rebrand them for the trade; we engineer for the shop first.

Application-Specific Design

A Tahoe battery faces different demands than a Spark battery — duty cycle, under-hood temperatures, accessory loads, and vibration profiles all vary by platform. Our engineering accounts for these differences rather than offering one-size-fits-all solutions with vague “universal fit” claims.

Cold-Climate Performance

Cranking amps matter most when the temperature drops below freezing. We test our batteries under the same severe-weather conditions that strand drivers on winter mornings — ensuring rated CCA translates to actual starting power when oil thickens and chemical reactions slow.

Accessible Technical Support

When a technician calls with a fitment question or a warranty claim, they reach someone who understands battery chemistry and vehicle electrical systems — not a script-reading call center. Our support infrastructure reflects the same professional focus as our product lineup.

Trusted Across Applications

Independent Shops
Service centers rely on our Professional series because warranty returns disrupt workflow and damage customer trust. When a battery comes back, it costs more than the part — it costs labor hours and repeat diagnostic time that could be spent on billable work.
Fleet Operations
Commercial fleets running Silverados and Sierras choose our AGM batteries for routes that combine severe duty cycles with minimal maintenance windows. A roadside failure doesn’t just mean towing costs — it means missed deliveries and schedule disruption across the entire operation.
DIY Enthusiasts
Car owners who maintain their own vehicles value the same engineering quality professional technicians demand — predictable cranking power, straightforward installation, and warranty coverage that doesn’t require proving the battery failed under ideal laboratory conditions.

Experience Professional-Grade Power

Whether you’re replacing a battery in your driveway or outfitting an entire fleet, our lineup delivers the same engineering standards General Motors has relied on for over a century.
