In late January 23, 2026, a fire broke out in the basement battery room of the GlobalSwitch data center located in the Blackwall area of East London, drawing attention to the safety of lead-acid battery systems and their supporting accessories in critical infrastructure. The fire involved approximately 200 lead-acid batteries, and 60 firefighters with 8 fire engines put out the fire after nearly two hours of emergency disposal. No casualties were reported in the accident, nor did it cause significant impacts on internet services or power supply. However, this incident has highlighted the potential risks of battery failures and the important role of high-quality fire-proof accessories in preventing and mitigating such hazards—especially in scenarios like data centers, where even minor safety loopholes may lead to catastrophic losses.

The London Fire Brigade stated that the fire originated from a battery failure in the basement of this 13-story building, but the specific cause (thermal runaway, short circuit, or UPS failure) is still under investigation. For lead-acid battery systems, high-performance fire-proof supporting accessories are essential to enhance safety, as the reliability of such components is closely related to the prevention of fire spread. This incident clearly reminds us: the safety of lead-acid batteries depends not only on the quality of the batteries themselves but also on the support of high-performance fire-proof supporting accessories.

This fire incident has raised awareness of lead-acid battery safety among relevant enterprises, many of which are paying more attention to improving the safety of their own battery systems. As a leading enterprise in the industry, our company has been supplying fire-proof accessories, such as separators, safety valves, battery indicators, and battery cases, to minimize losses when battery failures occur.

Our AGM separators are made of high-quality glass microfibers, which can fully absorb electrolyte, eliminate free acid, reduce the risk of leakage, and are consistent with the safety standards of global lead-acid battery manufacturers. They extend the service life of lead-acid batteries and reduce maintenance costs for customers.

The London data center fire has already shown that: for the safety of lead-acid batteries, every component is crucial. Our certified fire-proof solutions can provide reliable protection for lead-acid battery systems. With the increasing emphasis on safety in the industry after the fire, we will continue to commit to providing high-performance, ISO-certified accessories, helping global customers protect critical infrastructure and avoid the recurrence of similar tragedies. Choosing our certified fire-proof accessories means choosing the most reliable line of defense against lead-acid battery fire risks.
