Backup Power System Batteries

Backup Power Systems applications

Backup power systems protect operations from outages of any length. Homes, offices, hospitals, data centres and critical infrastructure all use batteries to carry essential loads during mains interruptions, blackouts and emergencies. Well specified energy storage keeps services running and protects safety, security and continuity where conventional supply cannot be relied on.

For over two decades, Ultracell has supplied energy storage for standby and backup applications. Our range covers VRLA AGM and Gel batteries, long life OPzS and OPzV tubular batteries, and Lithium LiFePO₄ (lithium iron phosphate) systems. Pure Lead batteries are available for specialist projects needing rapid recharge, strong cycling resilience or long service life. All Ultracell batteries are manufactured under ISO 9001 certified quality management and ISO 14001 certified environmental management and tested before dispatch, so system designers can specify them with confidence.

Ultracell works with system integrators, installers and end users who need dependable backup power, supported by consistent manufacturing quality.

Choosing Backup Power Batteries

In a backup system, the battery is the component that carries the load when mains supply fails. It must respond instantly and deliver stable energy to emergency lighting, security systems, communications, medical devices, IT infrastructure and industrial processes.

Ultracell designs for extended service life, high rate discharge and safe, maintenance free operation. Whether the requirement is residential backup, business continuity or national infrastructure, the right battery depends on load, runtime, space and environment. Ultracell can help specifiers weigh these factors across the range.

Applications

  • Data centres and IT infrastructure
  • Hospitals, clinics, and medical equipment
  • Telecommunications and network nodes
  • Residential and commercial backup systems
  • Security, fire, and emergency systems
  • Industrial and utility backup
  • Critical infrastructure and transport networks
  • Government and defence facilities
  • Emergency lighting and safety systems

Frequently Asked Questions

The best battery depends on duty. UL and UXL VRLA ranges suit general standby applications, with maintenance free operation. The UHR series suits high rate discharge where instant power is critical. For larger or long duration systems, UZS OPzS and UZV OPzV tubular batteries provide durable endurance. For space efficient installations, ULIT and ULIT-R lithium offer high energy density and rapid recharge, and ULIT-R is designed for rack mounting.

Stable voltage, consistent capacity retention and dependable construction determine whether a battery performs when mains supply fails. Ultracell manufactures under ISO 9001 certified quality management and ISO 14001 certified environmental management, which supports consistent results and continuity of operation.

Yes, for many applications. Ultracell ULIT and ULIT-R LiFePO₄ batteries combine long cycle life, rapid recharge and compact design. They suit telecom infrastructure and facility backup where efficiency, space savings and low maintenance matter, and they include an integrated battery management system. Please note: ULIT and ULIT-R batteries are not recommended for use in Uninterruptible Power Supply (UPS) systems. For UPS installations, the Ultracell UHR high rate VRLA series is engineered to deliver the rapid discharge and instant response required.

Ultracell has supplied backup batteries for over 25 years across healthcare, telecoms, utilities and critical infrastructure projects worldwide. Every battery is tested and manufactured under ISO 9001 certified quality management and ISO 14001 certified environmental management. Customers receive consistent reliability, long service life and a broad range of technologies to match load, runtime and budget.
