About S9 Battery Testing Lab
We’re an independent battery testing lab based in Massachusetts, helping product teams and researchers get fast, accurate data without building their own facilities.
Who We Are
S9 is a third-party battery testing lab based in Wilmington, Massachusetts. We specialize in cell-level testing for lithium-ion, lithium-metal, and solid-state battery formats used in research, product development, and small-scale manufacturing. Our team supports startups, research labs, and engineering groups with reliable testing for performance, safety, cycle life, and environmental conditions.
We focus on speed, accuracy, and flexibility to help our clients move from prototypes to data-backed decisions without the cost of building an in-house lab.

The S9 Way: Nine Ways Forward
A framework inspired by our name. The 9 principles that guide our testing, service, and impact.
Speed
Rapid protocols and faster test results. We accelerate testing timelines, helping clients move from development to deployment with minimal delays.
Safety
Meeting the strictest safety requirements. Our processes are designed with built-in safety measures, ensuring compliance with the highest industry standards.
Service
Round-the-clock support. No exceptions. We provide 24-hour support, responding quickly to challenges so our clients can stay on track.
Solutions
Testing built for real-world needs. We don't believe in one-size-fits-all, our solutions are customized to match specific project requirements.
Standards
Testing to the highest industry benchmarks. We validate batteries against global regulations and ensure every test meets strict compliance requirements.
Science
Academic precision meets industrial efficiency. Our expertise combines research-based methodologies with real-world application to deliver high-precision results.
Savings
Advanced testing at industry-leading prices. By optimizing our processes and using in-house technology, we offer high-value solutions at a lower cost.
Scalability
From single cell to mass production - always flexible. Our testing capabilities scale with client needs, from prototypes to larger-scale manufacturing.
Strategy
Aligning every test with your market goals. We don't just test batteries; we provide insights that help clients make strategic decisions.
