About Maccor

Defining the Standard in Battery Testing, Built in America since 1987

For nearly 40 years, Maccor has designed and manufactured the world's most trusted battery test equipment — right here in Tulsa, Oklahoma. From the first lithium-ion research labs to today's largest EV gigafactories, our systems power the discoveries that power the world.

From a Tulsa Workshop to a Global Standard

Maccor was founded in 1987 with a single conviction: battery researchers and manufacturers deserved test equipment that was as rigorous as the science itself. What began as a small team of engineers in Tulsa, Oklahoma has grown into the global benchmark for battery cycler systems and precision test equipment.

Every instrument we build still leaves our Tulsa facility — designed, assembled, and verified by our in-house engineering team. That commitment to domestic manufacturing isn't just tradition; it means tighter quality control, faster support, and accountability to every customer who depends on our systems.

Today, Maccor hardware and software are running in over 1,000 facilities across more than 50 countries, supporting applications that range from implantable medical devices to grid-scale energy storage and next-generation EV batteries.

Why We Build What We Build

Batteries store the energy of the future — clean transportation, renewable power, life-saving devices. Our mission is to give every researcher, engineer, and manufacturer the measurement confidence they need to make that future safer and better.

🎯

Accuracy Without Compromise

We hold ourselves to the same standard we set for our instruments. From ±6 nA research systems to high-volume formation lines, Maccor precision is never an afterthought — it's the foundation of everything we make.

🔩

American Manufacturing

Every Maccor system is designed, built, and tested in Tulsa, Oklahoma. Domestic manufacturing keeps quality in our hands and puts our engineers in direct contact with the people who depend on our equipment every day.

🤝

Partnership Over Transactions

We don't ship a box and disappear. Our engineers become an extension of your team — from initial specification through commissioning, calibration, and decades of ongoing support.

🔬

Continuous Innovation

Battery chemistry, cell formats, and testing standards evolve constantly. So do we. The Series 6000 platform, FUSION integrated systems, and our software suite represent decades of listening closely to the scientists and engineers on the front line of battery research.

🌍

Global Reach, Local Accountability

With installations across more than 50 countries, we understand the stakes of global battery supply chains. We back every system with local support infrastructure so that a test line in Seoul or Stuttgart gets the same responsiveness as one down the street from our Tulsa facility.

Advancing the Energy Transition

Electrification depends on better batteries. Better batteries depend on better testing. We're proud to be part of the infrastructure that's accelerating cleaner energy — one charge cycle at a time.
