Add runtime where it matters with the Eaton BP36RT 36 V extended battery module. Built for SmartOnline UPS systems, this 2U rack/tower battery module gives infrastructure teams a clean way to expand backup duration without changing the core UPS platform. That matters in environments where outages are measured in minutes, not hours. An extended battery module helps bridge longer utility interruptions, controlled shutdown windows, and generator transfer gaps while preserving the UPS architecture already in place. The rack/tower format also supports deployment flexibility, making it easier to align power protection with the physical layout of the site. For IT directors and systems architects, the value is straightforward: more runtime, less disruption, and a better fit for critical loads that cannot afford a short battery window. It is the kind of accessory that earns its place by extending the usefulness of a premium UPS investment.
