Eaton’s lithium-ion battery systems provide a compact, reliable and flexible solution that ensures 24/7 system uptime while delivering significant total-cost-of-ownership (TCO) savings. Capable of providing megawatts of power in a small footprint, this battery solution is comprised of lightweight battery strings designed to seamlessly connect to an Eaton 9395 family UPS or 93PM UPS.
Lithium-ion chemistry offers exceptional advantages in UPS applications due to it's lightweight design and high energy density, allowing more energy storage in compact spaces. These batteries last longer, enduring more charge cycles with fewer replacements and reducing long-term costs. Lithium-ion batteries also charge quickly, exhibit higher efficiency and have lower cooling needs due to a wider temperature tolerance. Additionally, the integrated advanced battery management system (BMS) monitors and regulates system performance and can operate on either internal DC logic power or AC logic power supplied by the customer.
Litihum-ion UPS battery technology offers numerous advantages including a lifespan of up to 15 years. Learn more about battery safety, operational functionality, code compliance and more in this comprehensive FAQ.
With a higher power capacity, lithium-ion batteries enable three-phase UPS systems to deliver robust performance within a confined physical footprint, and their extended lifespan reduces complexities and cost savings in large installations.
