APC SYBT9-B6 Battery Module for Symmetra PX 250/500kW | UPS Battery

Keep high-density power protected when outages last longer than a standard battery string can cover. The APC High Performance Battery Module for the Symmetra PX 250/500kW is designed for Symmetra PX environments that demand predictable runtime, serviceable battery architecture, and compatibility with large-scale UPS deployments. With 5,184 VAh of capacity and lead-acid chemistry, this module is built for enterprise power rooms where runtime planning matters. The specified battery life range of 5 to 8 years supports long-term deployment planning, while the 1-year limited warranty provides a clear service baseline for procurement and support teams. At approximately 336.6 lb, this is a substantial battery module intended for serious infrastructure, not light-duty backup. Its dimensions are sized for the Symmetra PX platform, and the module ships with an installation guide to support controlled replacement workflows. For teams protecting core compute, storage, and network loads, this battery module helps preserve uptime, reduce risk during transfer events, and maintain orderly shutdown capability when utility power is unstable.
