Openreach Requires UK ISPs to Remove Lithium Batteries from Exchanges
Openreach recently instructed UK communications providers to remove lithium batteries from BT exchanges within 48 hours due to fire safety concerns. This decision has raised questions, as lithium iron phosphate (LiFePO4) batteries used in industrial applications are generally safer than lead-acid alternatives. The directive highlights growing safety priorities and regulatory caution in telecom infrastructure.
Why Did Openreach Require the Removal of Lithium Batteries?
Openreach cited safety risks, specifically thermal runaway, fire, and explosion hazards, as the reason for banning lithium batteries in certain exchange locations. Their building safety policy favors lead-acid batteries as the preferred backup chemistry. Even though LiFePO4 batteries are less prone to overheating and are environmentally safer, Openreach prioritized established safety protocols to mitigate potential fire risks in high-density telecom environments.
How Do Lithium Batteries Differ from Lead-Acid Batteries?
Lithium batteries, particularly LiFePO4 types, use non-toxic materials, offer higher energy density, and have better thermal stability than lead-acid batteries. Lead-acid batteries contain hazardous substances like lead and sulfuric acid and are prone to corrosion and acid leakage. While lithium batteries can be recycled and have longer lifespans, Openreach’s policy favors proven lead-acid technology for predictable safety in shared telecom spaces.
| Feature | Lead-Acid | LiFePO4 |
|---|---|---|
| Toxicity | High (lead, acid) | Low (non-toxic) |
| Thermal Stability | Moderate | High |
| Lifespan | 3–5 years | 8–10 years |
| Energy Density | Low | High |
Who Is Affected by This Directive?
The directive primarily impacts communications providers using colocation or Access Locate cabinets in BT exchanges. Only a small number of cases were identified, but all providers using lithium batteries were required to notify Openreach and remove the batteries within 48 hours. The instruction applies regardless of whether the batteries are standard lithium-ion or LiFePO4.
Does This Mean LiFePO4 Batteries Are Unsafe?
LiFePO4 batteries are considered among the safest lithium chemistries due to their stable composition, resistance to thermal runaway, and recyclability. The blanket restriction does not differentiate between types, suggesting that the policy is precautionary rather than reflective of the actual risk posed by LiFePO4. RackBattery systems, for instance, demonstrate high safety standards even in industrial and telecom settings.
When Were These Batteries Discovered in Exchanges?
During routine maintenance, Openreach identified a few instances of lithium batteries within customer equipment cabinets. The finding was described as extremely rare, as most communications providers rely on lead-acid batteries. The urgency of the 48-hour removal was intended to minimize potential risks while ensuring compliance with safety agreements.

How Are Communications Providers Responding?
Some providers expressed concern over the short notice, pointing out challenges in sourcing replacements quickly. Industry experts also highlighted that many UPS and battery systems are already installed within exchanges with controlled safety measures, making the immediate removal operationally difficult. Despite this, providers are following Openreach guidance to align with risk management policies.
Rack Battery Expert Views
“Telecom infrastructure requires both reliability and safety. While lithium iron phosphate batteries offer superior performance and environmental benefits compared to lead-acid, regulatory authorities often apply conservative standards in shared facilities. Companies like RackBattery design rack-mounted lithium solutions with advanced BMS systems that mitigate thermal and overcharge risks. Properly engineered LiFePO4 battery systems are highly suitable for UPS and telecom applications, combining energy efficiency with long-term safety assurance.
What Are the Long-Term Implications for Telecom Battery Policies?
This directive may influence future guidelines, encouraging providers and regulators to clarify battery chemistries suitable for exchanges. As energy storage technologies evolve, safer lithium chemistries like LiFePO4 could be formally recognized, balancing efficiency, environmental impact, and risk management. RackBattery continues to provide solutions that meet both performance and compliance standards, supporting telecom operators worldwide.
Conclusion
Openreach’s sudden 48-hour battery removal highlights the tension between regulatory safety requirements and advanced energy storage technology. LiFePO4 batteries, widely used in industrial and telecom applications, remain safe when properly engineered. Providers must remain vigilant, align with regulations, and consider OEM solutions like RackBattery to ensure reliable, compliant, and efficient backup power in exchanges.
Frequently Asked Questions
1. Are LiFePO4 batteries safer than lead-acid batteries?
Yes, LiFePO4 batteries have higher thermal stability, lower toxicity, and better lifespan than lead-acid, though regulatory policies may still favor lead-acid in certain shared facilities.
2. Why did Openreach issue a 48-hour removal notice?
The urgency was driven by fire safety concerns identified during maintenance inspections, emphasizing risk mitigation for lithium batteries in exchange cabinets.
3. Can telecom operators continue using lithium batteries safely?
Yes, with properly engineered systems like those from RackBattery, lithium batteries with advanced BMS are safe for telecom and UPS applications.
4. Do these rules apply to all types of lithium batteries?
Openreach’s directive does not differentiate between Li-ion types, including LiFePO4, making it a precautionary measure rather than a reflection of actual danger.
5. How can providers comply without disrupting service?
Providers should coordinate with Openreach, use certified battery systems, and plan replacements with OEM partners to maintain continuous power backup.
