Description
APC Smart-UPS SRT Battery Pack – 48V 594VAh External Battery Module for 1kVA & 1.5kVA Rack/Tower UPS Systems
The APC Smart-UPS SRT Battery Pack (48V, 594VAh) is a high-capacity, hot-swappable external battery module engineered to extend runtime for APC Smart-UPS SRT 1kVA and 1.5kVA uninterruptible power supply (UPS) systems. Designed for small to mid-sized server rooms, network closets, and edge IT environments, this scalable battery solution ensures critical equipment—including servers, switches, firewalls, and storage devices—remains powered during utility outages, enabling graceful shutdowns or bridging to generator power.
As part of APC’s trusted Smart-UPS SRT (Smart-UPS RT) series, this 48V battery pack delivers enterprise-grade reliability, intelligent battery management, and seamless integration with APC’s power protection ecosystem—allowing IT administrators to customize backup duration without over-provisioning their primary UPS.

Why Extend Runtime with This 48V Battery Pack?
The internal batteries of the SRT 1kVA/1.5kVA UPS typically provide 5–15 minutes of runtime at full load—often insufficient for:
- Automated, orderly shutdowns of virtualized environments (VMware, Hyper-V)
- Riding through short outages in areas with unstable grid power
- Supporting generator startup (which may take 10–30 seconds, but longer runtimes add safety margin)
By adding one 48V 594VAh battery pack, runtime can be doubled or tripled, depending on load. For example:
- At 500W load, a single SRT1500XLA + one battery pack may provide 30–45+ minutes of backup
- At 300W load, runtime can exceed 60 minutes
This flexibility ensures your critical systems stay online long enough to: ✅ Complete backup scripts
✅ Notify administrators
✅ Maintain uptime during brief grid fluctuations
Seamless Integration with Smart-UPS SRT 1k/1.5kVA
This battery pack is not a generic solution—it’s specifically engineered for APC’s 48V SRT platform, ensuring:
- Automatic recognition by the UPS upon connection
- Accurate runtime calculations in PowerChute and UPS LCD display
- Balanced charging between internal and external battery strings
- Unified monitoring—no third-party software or complex setup
Installation is simple: connect the included high-current DC cable from the battery pack to the UPS’s external battery port, and the system auto-configures.
Hot-Swappable Design for Continuous Operation
Unlike traditional UPS battery replacements that require downtime, this pack supports hot-swappable maintenance:
- Replace aging or failed batteries while the UPS is online
- Minimize risk during business hours
- Extend total system life through modular upgrades
Note: While the pack supports hot-swap, individual battery modules inside may require brief disconnection—always follow APC’s service guidelines.
Ideal Use Cases
- Small business server rooms running file servers, NAS, or domain controllers
- Network closets with core switches, firewalls (e.g., Cisco Meraki MX, FortiGate), and wireless controllers
- Retail POS systems requiring PCI-compliant uptime
- Healthcare clinics with EMR workstations and imaging devices
- Remote edge sites with limited on-site IT support
