DATA CENTRE UPS BACKUP POWER,

System Overview

This installation supports critical data centre infrastructure through multiple UPS systems supplied by Eaton, providing reliable standby backup power for essential operations.

UPS Infrastructure

6 × 600 kVA UPS systems
3 × 300 kVA UPS systems

These systems ensure uninterrupted power protection for mission-critical data centre loads.

Battery Installation

Battery Type HRL12540W
Total Batteries Installed 1200 units
Battery Room Temperature 25°C (controlled environment)

The batteries were installed across three manufacturing batches as part of the original UPS battery banks.

Operational Performance

The 2013 batch of batteries (400 units) was replaced in 2024 after approximately 11 years of service.

Typical VRLA Expectations

Design life 10 years
Typical expected service life 7–8 years in UPS applications
Actual achieved service life 11 years

The extended service life can largely be attributed to:

Controlled battery room temperature
Stable UPS charging conditions
Data centre environmental control
Routine monitoring and maintenance

Planned Replacement

The remaining batteries from 2014 and 2015 are scheduled for replacement during 2026, placing them at approximately:

11–12 years of operational service

This continues to exceed the typical service expectations for VRLA batteries in UPS environments.

UPS Backup Power Installation

Conclusion

This installation demonstrates the long-term reliability of HRL12540W batteries in a mission-critical data centre environment.

Although the batteries carry a 10-year design life, they successfully achieved 11–12 years of operational service, exceeding the commonly expected 7–8-year lifespan in UPS applications.

Key Conditions Maintaining the following conditions was key to maximizing battery lifespan:

Stable ambient temperature (25°C)
Proper UPS charging conditions
Routine monitoring and preventative maintenance
Controlled data centre environment
