EXS External Battery Cabinet 50Ah 1 String VRLA Vertiv | UPS Battery

Add runtime where it matters with the EXS External Battery Cabinet, 50 Ah, 1 String VRLA. For UPS deployments that need more ride-through than the base system can provide, an external battery cabinet is the practical way to increase backup duration without changing the core UPS platform. This cabinet is suited to environments where outage tolerance is measured in minutes, not assumptions. By moving additional battery capacity into a dedicated enclosure, it helps preserve protected-load continuity during longer transfers, generator start delays, or controlled shutdown sequences. The 50 Ah capacity and single-string VRLA configuration make it a straightforward fit for planned power expansion in enterprise and edge sites. For IT teams, the value is control. You can size runtime more precisely, keep the UPS electronics separate from battery expansion, and support maintenance planning with a dedicated battery cabinet instead of overloading the base unit. In critical power design, that separation matters. It gives you a cleaner path to longer runtime and a more deliberate backup strategy.
