Background
A leading telecommunications provider in the United Kingdom (UK) operates an extensive network that includes fixed-line and mobile communications, internet services, and TV applications. In addition, it manages data centers across mainland Europe and operates one of the largest and most prominent mobile network infrastructures in the UK and Europe.
With an extensive telecommunications infrastructure, maintaining the reliability and efficiency of backup uninterruptible power supply (UPS)systems is crucial. This is especially true for data centers, network operations, and tower sites, where power outages can lead to significant service disruptions and revenue loss. Recognizing the need for improved UPS battery maintenance and cost efficiency, the company sought to optimize its battery replacement processes.
Challenge
The company historically followed a fixed schedule for battery replacements, typically replacing batteries at the end of the manufacturer’s warranty. This approach resulted in unnecessary costs, as many batteries were still operational and capable of delivering reliable service.
The company faced two primary challenges:
- Identifying which batteries were still functional and which were nearing the end of their life cycle.
- Reducing costs associated with unnecessary battery replacements while maintaining service integrity.
Traditional testing methods lacked the precision needed to assess battery health accurately. The company required a solution that could deliver real-time insights into the state of health (SOH) of each battery, enabling informed decisions regarding replacements.
Implementation
Franklin Electric Grid Solutions provided a robust battery testing and management solution to address these challenges. At the core of the solution was the CELLTRON™ Advantage Digital (CADD) Handheld Battery Tester, it was selected for its precision in testing and monitoring industrial batteries.
The provider will be able to:
- Accurately test for conductance
- Filter digital signals
- Complete testing faster
- Protect users and the device
- Transmit data from the tester wirelessly
To further support its battery management goals, the provider leveraged several key testing methodologies to accurately assess battery health and optimize replacement strategies.
Conductance Testing
This tester uses conductance testing, a more precise technique for evaluating battery health by measuring how effectively a battery can deliver power to essential systems. This accuracy was critical, as even minor battery performance issues could have significant operational consequences.
High Noise Immunity
The powerful dual-microprocessor architecture of the CADD allows it to withstand high noise environments caused by UPS battery systems and constant power supply switching which is notorious for causing testers to fail.
WITH THE BATTERY MONITORING SYSTEM THIS TELECOMMUNICATIONS PROVIDER ACHIEVED:
Accurate and Reliable Testing:
Conductance testing provided precise assessments of battery health, reducing unnecessary replacements and can be used as a reliability predictor of the battery’s end of life.
Digital Signal Filtering:
Cleaner, more precise battery state-of-health measure were achieved through edge rejection technology which filtered out anomalies that can corrupt battery signal readings during the beginning and end of each sample signal.
Faster Testing Times:
Testing is carried out in a matter of seconds simply by connecting the two test leads to the battery’s posts instead of performing lengthy discharge tests.
Remote Battery Management:
Through UNITE™ Battery Asset Management database users can wirelessly pre-program and export plant and string details to the handheld tester and upload test results to the database via Wi-Fi before leaving the site.
Conclusion
Through its collaboration with Franklin Electric Grid Solutions, the company enhanced its battery management strategy, leading to improved operational resilience and cost efficiency. By leveraging advanced testing technology, the company gained real-time insights into battery health, allowing for proactive maintenance and extended battery life.
The deployment of CADD Digital Handheld Battery Testers, combined with Franklin Electric’s expertise, enabled precise monitoring and optimized battery performance. This data-driven approach has strengthened operational reliability, ensuring backup power remains effective while reducing unnecessary maintenance costs. As the telecommunications industry evolves, intelligent battery management will continue to play a vital role in sustaining uninterrupted service and long-term infrastructure reliability.
