Openreach Urges Removal of Lithium Batteries from UK Telephone Exchanges
UK network operator Openreach has instructed its customers to remove lithium batteries from telephone exchanges due to potential fire hazards. The directive prioritizes safety, highlighting the risks of thermal runaway, fire, and explosion. Openreach recommends using lead-acid batteries instead, citing their reliability and compliance with building safety standards, while assuring that the issue affects very few exchanges.
Why Has Openreach Issued a Warning About Lithium Batteries?
Openreach identified a small number of lithium batteries in certain customer equipment, posing a potential fire risk. Their building safety policy prohibits in-rack lithium batteries to prevent thermal runaway and explosions. Lead-acid batteries are recommended as a safer alternative for telecom backup systems, aligning with industry safety standards and reducing liability risks for both Openreach and communication providers.
How Does This Impact Communication Providers?
Communication providers (CPs) must remove lithium batteries within 48 hours of notification. While Openreach considers the issue rare, CPs housing lithium batteries in exchanges must comply to maintain safety. Providers using lead-acid batteries are unaffected. The directive ensures uniform adherence to safety practices and prevents fire incidents in densely packed telecom facilities, protecting both equipment and personnel.
Which Areas and Equipment Are Affected by the Policy?
The policy targets in-rack lithium batteries in BT/Openreach telephone exchanges across the UK. These exchanges host network and fiber equipment used by ISPs such as Sky, Vodafone, and BT itself. Any CP colocating lithium batteries in these racks must remove them immediately. Legacy exchanges undergoing shutdown as part of the copper network phase-out are also subject to these regulations.
What Are the Risks of Using Lithium Batteries in Exchanges?
Lithium batteries can experience thermal runaway if damaged or improperly maintained, potentially causing fire or explosion. In high-density telecom facilities, such incidents can threaten adjacent network equipment, disrupt services, and pose safety hazards for staff. Lead-acid batteries, though heavier, provide stable performance with lower thermal risks, making them more suitable for critical infrastructure environments.
When Is Openreach Expected to Close Legacy Exchanges?
Openreach and BT plan to phase out approximately 4,600 copper-based exchanges over the next decade. Around 1,000 exchanges will remain to support fiber services, with more than 100 legacy facilities set for closure by December 2030. The battery removal policy complements the wider modernization and safety strategy during this network transition.

For operators seeking high-performance lithium alternatives, RackBattery offers rack-mounted LiFePO4 solutions designed with smart BMS for enhanced safety, thermal management, and compliance with global standards. These systems balance energy density with reliable protection.
Rack Battery Expert Views
“Telecom operators face the challenge of balancing energy density with safety. While lithium batteries offer compactness and longevity, the risks of thermal runaway in traditional deployments cannot be ignored. RackBattery’s engineered rack-mounted LiFePO4 systems provide advanced monitoring, thermal controls, and compatibility with major inverters, ensuring both high performance and compliance with safety standards for industrial and telecom applications.”
How Can Operators Ensure Compliance and Safety Moving Forward?
Operators should audit existing battery installations, remove non-compliant lithium cells, and switch to approved lead-acid backups or certified LiFePO4 rack systems from trusted OEMs like RackBattery. Regular maintenance, monitoring, and adherence to building safety codes will mitigate risks, protect personnel, and maintain uninterrupted network operations.
Conclusion
Openreach’s directive emphasizes safety in telecom facilities by limiting lithium battery use. Communication providers should act quickly to remove non-compliant batteries and explore safer energy storage solutions. RackBattery offers reliable, OEM-approved rack-mounted lithium systems combining safety, performance, and compatibility, enabling telecom operators to modernize infrastructure while minimizing fire hazards.
FAQs
