APC Smart-UPS VT Extended Battery — VRLA Backup Power

The APC Smart-UPS VT Extended Battery with Valve-Regulated Lead Acid (VRLA) chemistry delivers scalable, reliable backup power for critical systems. Designed for data centers, server rooms, network closets, and edge environments, this external battery solution extends runtime for the Smart-UPS VT platform while preserving the pristine power quality that IT equipment depends on. With VRLA cells, maintenance-free operation, and seamless integration with APC’s power management ecosystem, you gain the peace of mind that comes from continuous uptime, safer shutdowns, and proactive monitoring. This extended battery module is purpose-built to protect sensitive electronics from outages, voltage sags, and transient spikes, ensuring your workloads stay online when it matters most.

• Scalable runtime with external battery modules: Extend the operational window for critical devices by adding modular external battery packs to the Smart-UPS VT. This scalable approach lets you tailor protection to your specific tolerance for downtime, enabling longer runtimes during outages and more time for graceful shutdowns during maintenance. As your load grows or service windows tighten, you can incrementally increase energy capacity without replacing the entire UPS, delivering a lower total cost of ownership and flexible capacity planning for growing IT environments.
• Premium power quality and protection: The Smart-UPS VT delivers continuous, clean power through double-conversion online topology, producing a stable true sine wave that remains consistent despite fluctuations on the incoming supply. Automatic Voltage Regulation (AVR) corrects minor sags without switching to battery, preserving battery health for longer life. In the event of a mains outage, seamless transfer to battery occurs with zero transfer time, protecting sensitive servers, storage arrays, and networking gear from disruptive power events and preserving application integrity during transition periods.
• Intelligent management and monitoring: Gain complete visibility into battery health, runtime, and load with integrated management options. The external battery extension communicates with the UPS to deliver real-time status through onboard displays, USB, or serial interfaces. APC’s ecosystem supports PowerChute software and compatibility with IT management platforms, enabling automated shutdowns, energy-use monitoring, and detailed reporting. For larger deployments, centralized monitoring through EcoStruxure IT or SNMP-compatible tools provides holistic oversight across multiple sites and devices.
• Reliability, safety, and maintenance advantages: VRLA chemistry offers a sealed, maintenance-free solution with reduced risk of electrolyte leakage and minimal service requirements. The extended battery family is engineered for consistent performance in controlled environments, with battery management features that track charge cycles and degradation to optimize life expectancy. External battery packs are designed for straightforward replacement, lowering downtime and simplifying maintenance windows for data centers and enterprise networks alike.
• Flexible installation and deployment: This extended-battery option is built for adaptable deployments, with mounting versatility and cable routing designed to suit rack, floor, or cabinet configurations. Clear labeling and robust connectors simplify connection to the Smart-UPS VT, while the modular design supports space optimization and easy future upgrades. Whether your footprint is compact or expansive, the battery extension can be integrated without disrupting existing IT operations, enabling a smooth, scalable path to enhanced resilience.

How to install APC Smart-UPS VT Extended Battery

• Power down all connected equipment and ensure the UPS is unplugged before beginning installation of the external battery module. Safety first prevents accidental shocks or equipment damage.
• Inspect the new external battery pack for any signs of damage or shipping-related issues. Do not install if packaging is compromised or if the battery appears damaged.
• Plan the installation location to provide adequate ventilation and room for airflow. Avoid moisture, direct sunlight, and extreme temperatures to maximize battery life and performance.
• Connect the external battery module to the Smart-UPS VT using the provided interface cables, following the orientation guides and polarity indications in the installation manual. Ensure all connectors are fully seated and secured.
• Power up the UPS and the battery extension, then verify the connection through the UPS display or management software. Run a self-test if available to confirm battery health and runtime calculations are accurate for your load.
• Re-connect your protected loads and monitor the system for normal operation. If you notice any irregular behavior, consult the user manual and, if needed, schedule a service check with APC support to verify the extended configuration.

Frequently asked questions

• Q: What is the APC Smart-UPS VT Extended Battery? A: It is an external battery extension designed to work with APC Smart-UPS VT, using VRLA cells to deliver reliable, maintenance-free backup power that increases runtime for critical equipment during outages.
• Q: How does the extended battery affect uptime? A: Runtime increases with added battery capacity. The total protection time depends on the load connected to the UPS; lighter loads will gain more run-time percentage, while heavier loads will benefit from the additional energy available to sustain critical functions or to enable a controlled shutdown.
• Q: Is installation safe for non-professionals? A: Basic installation can be performed by trained personnel following the official manual. For large deployments or high-value equipment, professional installation is recommended to ensure correct connections, safety compliance, and optimal performance.
• Q: Can I mix different external battery packs? A: Use only external battery modules specified for the APC Smart-UPS VT family. Mixing non-approved packs can compromise performance, safety, and warranty coverage.
• Q: How do I monitor battery health and status? A: Use the UPS display, USB/Serial interfaces, and compatible management software (PowerChute, EcoStruxure IT) to track charge status, battery age, health indicators, and to schedule regular self-tests for proactive maintenance.
