APC SRV72BP-9A External Battery Pack — 72V Tower

The APC SRV72BP-9A External Battery Pack delivers extended runtime protection for your critical networking infrastructure and server equipment. Designed specifically for APC Easy UPS On-Line SRV series units (2/3kVA models), this 72V tower configuration provides substantial backup capacity with 1296VAh of reliable battery power. When your UniFi network stack, security cameras, or business-critical systems absolutely cannot go down, this external battery pack ensures your UPS can sustain loads through extended outages that would exhaust standard internal batteries.

• Extended Runtime Capability: Significantly increases backup time beyond base UPS capacity, ideal for protecting multi-switch deployments, NVR systems, and core network infrastructure
• Hot-Swappable Design: Tower format allows for easy installation and future battery replacement without system downtime
• True Online Double-Conversion Protection: Works seamlessly with SRV series UPS units to provide zero-transfer-time power conditioning and protection
• Scalable Power Protection: Perfect for growing networks where adding battery capacity is more cost-effective than upgrading to larger UPS systems

For IT professionals managing UniFi deployments in small businesses, remote sites, or advanced home networks, this battery pack represents smart infrastructure planning. Rather than sizing your UPS for worst-case runtime scenarios from day one, you can start with the base SRV unit and add this external pack when extended protection becomes necessary. The investment pays dividends during storm seasons or in areas with unreliable utility power, giving you the confidence that your carefully configured network will remain operational through power events that would take unprotected systems offline.
