Discover the engineering and quality behind the renowned 40175L lithium-ion cell. Learn why Headway is the trusted manufacturer and how our cells power global innovations.
If you're in the market for high-performance cylindrical lithium-ion cells, you've undoubtedly come across the model 40175L. It's a popular choice for a wide range of applications, from power tools and portable equipment to backup systems and more.

But here's a crucial question: Do you know who manufactures your 40175L cells?
For years, many international buyers have known the model without knowing the maker. Today, we want to change that. The renowned 40175L cell is a flagship product developed and produced by Headway, under Zhejiang Xinghai Energy Technology Co., Ltd. Let's explore what makes the genuine Headway 40175L the reliable choice for engineers and businesses worldwide.

What Sets the Genuine Headway 40175L Apart?
While the specifications on the datasheet are impressive, the real value lies in the real-world performance and reliability.
- Proven Reliability in Demanding Fields: The 40175L cell is built on the same technological foundation that has made Headway a core supplier to global hydrogen energy leaders and a strategic partner to the high-end semiconductor industry. By the end of 2021, we had supplied over 10 million high-power cells to the hydrogen sector alone. This legacy of reliability is engineered into every 40175L we produce.
- Engineered for Consistency: Mass production is one thing; mass production with unwavering quality is another. Our automated production lines and stringent quality control processes ensure that every batch of 40175L cells meets the exact same high standards. This means predictable performance and longer lifecycle for your products.
- A Cell Designed for Integration: The 40175L isn't just a standalone component. It is designed to be the building block of superior battery packs. Its robust steel shell, stable voltage output, and excellent cycle life make it the ideal choice for OEMs and pack integrators who cannot afford compromises.
Don't Just Buy a Model – Partner with a Manufacturer
Choosing a generic "40175L" from an unknown source introduces risk into your supply chain. Choosing the Headway 40175L establishes a partnership.
As a direct manufacturer, Headway offers:

Evolving to Meet Your Needs: Introducing the Headway 40146L
As technology advances, so do our solutions. While the 40175L remains a testament to Headway's engineering excellence, we continuously optimize our product portfolio to better serve our customers' evolving requirements.
For many applications where the 40175L has been the top choice, we now recommend our 40146L lithium battery cell as a highly efficient alternative.
Why Consider the 40146L?
- Same Diameter, Optimized Height: The 40146L shares the same 40mm diameter as the 40175L, ensuring compatibility with existing battery pack designs and manufacturing processes. Its slightly reduced height (146mm vs. 175mm) offers greater design flexibility for space-constrained applications.
- Perfectly Balanced Capacity: With a 20Ah capacity, the 40146L delivers the ideal power for a wide range of applications-from electric mobility and solar storage to telecom backup-without over-engineering. For many use cases, 20Ah provides the perfect balance between energy density and practical requirements.
- Streamlined Production, Reliable Supply: As our current mainstream production model, the 40146L LiFePO4 cell benefits from optimized manufacturing processes and dedicated production lines. This ensures shorter lead times, consistent quality, and greater supply stability for your projects.
- The Same Headway Quality: Like the 40175L, every 40146L cell is built with Headway's commitment to safety, longevity, and performance. It carries the same certifications (CE, UL, RoHS) and is backed by our decades of lithium battery expertise.
Which Cell Is Right for You?
Both the 40175L and 40146L represent Headway's dedication to quality and innovation. The choice depends on your specific application requirements:
Choose the 40175L (25Ah) when maximum capacity and energy density in the same diameter are your top priorities.
Choose the 40146L (20Ah) for a perfectly optimized solution that balances performance, cost-efficiency, and faster availability.
Our engineering team is ready to help you select the ideal power solution for your unique needs.
