Battery pack expansion module DIGIT DN-170122 for UPS — 8×12V 9Ah batteries

The DIGIT DN-170122 battery pack expansion module is an external battery cabinet configured with eight 12V 9Ah sealed lead‑acid batteries to extend the runtime of compatible 2 kVA UPS systems. Designed as an add‑on power source, this expansion module increases available backup time for critical equipment such as servers, network devices and workstations without modifying the internal UPS. The module is suitable for rack or cabinet placement near the protected equipment and connects to the UPS using the appropriate external battery connector and cabling supported by DIGIT UPS models.

Advantages

This battery expansion module provides a straightforward way to increase emergency power duration while preserving the original UPS unit. Using eight series/parallel configured 12V 9Ah batteries, the module offers predictable additional runtime and supports hot‑swap maintenance of the UPS system when installed according to manufacturer instructions. The sealed lead‑acid batteries are maintenance‑free, offer stable performance in typical indoor environments and are widely compatible with UPS units designed for external battery packs.

Suitable for

• Extending backup time for small to medium 2 kVA UPS installations
• Protecting servers and network switches during power outages
• Providing longer runtime for critical workstations and point‑of‑sale systems
• Use in server rooms, telecommunication closets, and office equipment cabinets

Key specifications

• Battery type: sealed lead‑acid (VRLA)
• Battery configuration: 8 × 12V 9Ah cells
• Intended application: external expansion module for compatible UPS units (approx. 2 kVA class)
• Typical use environment: indoor, temperature‑controlled locations
• Installation form factor: external rack/cabinet mountable module
• Maintenance: valve‑regulated, low maintenance design

How to use

Place the battery expansion module in a stable, ventilated indoor location close to the UPS it will support. Follow the UPS manufacturer’s instructions for connecting external battery modules: power down the UPS if required, connect the module using the specified external battery cable and secure all connectors. After connection, verify the UPS recognises the external battery module and check runtime estimates via the UPS management interface or display. Allow the batteries to charge fully before relying on extended runtime for critical loads.

Usage recommendations

Install and commission the expansion module according to DIGIT and UPS manufacturer guidelines. Maintain room temperature within recommended ranges to prolong battery life, perform periodic visual inspections for cabinet integrity, and replace aged batteries as part of a regular maintenance schedule to ensure reliable backup performance.
