APC Symmetra RM XR Frame SYRMXR4 208/240 V | Battery Frame, UPS

Keep critical infrastructure running longer when utility power drops. The APC Symmetra RM XR Frame SYRMXR4 adds extended-run battery capacity to compatible APC Symmetra UPS systems, giving IT teams more time to ride through outages, complete graceful shutdowns, or bridge to generator power. Built as a rack-mount external battery pack, this frame uses sealed lead acid VRLA batteries with spill-proof, maintenance-free construction. Hot-swappable support helps reduce service disruption during battery maintenance, while the 2,448 VAh energy rating provides the reserve needed for demanding server, network, and telecommunications environments. The 208/240 V DC output aligns with higher-voltage UPS architectures where runtime density matters. At 19 inches wide and 7 inches high, it fits standard rack deployments without wasting space. For teams comparing battery expansion options, this frame stands out by pairing APC compatibility, extended-run design, and field service practicality in one purpose-built unit. If your environment depends on predictable uptime, this is the kind of battery frame that earns its place in the rack: not just backup power, but more control over how long your systems stay available when it matters most.
