BAK Battery's 314Ah Energy Storage Cell Redefines Long Life and Reliability

BAK Battery’s new square 314Ah high-capacity energy storage cell establishes a fresh benchmark for longevity, economy, and dependability, featuring an ultra-long cycle life of 10,000 cycles, a high energy density of 190 Wh/kg, 2P high-power capability, and discharge efficiency exceeding 95%.

This leap in cell performance stems from BAK’s deep innovation in multi-material systems and structural design. The 10,000-cycle lifespan significantly reduces the full lifecycle cost per kilowatt-hour for energy storage systems, delivering fundamental economic assurance for long-term operation. Moreover, the cell has passed the most stringent nail penetration test, ensuring safety and reliability at the source.

On the application front, the 314Ah cell demonstrates broad suitability. In home energy storage, its long life and high safety align perfectly with household demands for durability and peace of mind, helping maximize solar self-consumption. For commercial and industrial storage, the cell’s high-power response and ultra-long cycle traits enable effective peak shaving, load management, and substantially improved project ROI. Additionally, it serves as an ideal core component for large-scale applications such as generation-side paired storage and grid-side independent storage plants.

Today, competition in energy storage cells has moved beyond capacity alone toward a comprehensive focus on full lifecycle cost, safety, and technical sophistication. Through continuous innovation, BAK Battery addresses the core market needs for “cost reduction and efficiency gains” alongside “long-term reliability,” offering more valuable solutions for the global energy transition.
