Powering Telecom Across Extremes

Imagine a remote telecom site nestled in the scorching deserts of Arizona, where summer temperatures soar above 120°F, or a hidden cell tower perched in the frostbitten tundra of Alaska, enduring winter chills that plunge below -40°F. In these extreme environments, where the forces of nature constantly test the reliability of technology, telecom operators face a daunting challenge: ensuring that their backup power solutions can withstand the elements, not just to keep services running but to do so without incurring prohibitive costs.

In this battle against temperature extremes, conventional battery solutions falter, succumbing to shortened lifespans and frequent maintenance needs, thus escalating operational costs and complicating the task of providing uninterrupted service. The quest for a more robust, cost-effective solution seems endless, highlighting a critical gap in the telecom industry’s ability to maintain connectivity in the face of Mother Nature.

We know that necessity breeds invention, but we need a leap in energy storage solutions. That’s where companies like C&D Technologies are taking the reigns with new products like the TEL-HT series promise to redefine telecom backup power.

The Challenge(s)

Telecom operators worldwide grapple with a twofold challenge that impacts their bottom line and operational efficiency: the high costs of battery replacements and maintenance, and the quest for dependable power solutions capable of performing in extreme environmental conditions. Traditional valve-regulated lead-acid (VRLA) batteries, while widely used, often fall short in longevity and reliability, especially when subjected to the rigors of high or low-temperature environments. These conditions accelerate battery degradation, leading to increased water loss, grid corrosion, and, ultimately, a shortened lifespan. As a result, operators are forced into a cycle of frequent battery replacements and maintenance checks, driving up the total cost of ownership (TCO) and straining resources.

The critical nature of telecom infrastructure demands that backup power solutions not only provide reliability but also adaptability to a wide range of environmental conditions. From hot deserts to freezing tundras, the ability of a battery to maintain optimal performance without requiring extensive cooling or heating infrastructure is vital. Yet, the challenge extends beyond performance and cost-efficiency. As the world leans into sustainability, the environmental impact of these solutions, from manufacture through disposal, comes under scrutiny, adding another layer of complexity to the decision-making process for telecom operators seeking to balance cost, performance, and environmental responsibility.

A Solution

C&D Technologies introduced a game-changer for the telecom industry: the TEL-HT Series. This innovative lineup of high-temperature valve-regulated lead-acid (VRLA) batteries is specifically designed to address the critical pain points faced by telecom operators. The TEL-HT Series provides reliability, cost-efficiency, and durability and is engineered to thrive in the harshest of environments while offering significant cost savings.

The TEL-HT Series is appealing because it can lower the total cost of ownership for operators. This is achieved through the company’s advanced MSE Pure Lead technology and a suite of other innovations that extend the battery’s lifespan and reduce maintenance requirements. By creating a battery that not only lasts longer but also performs reliably in a wide temperature range of -40° to 160°F, C&D Technologies delivers a solution that significantly cuts down on replacement and maintenance costs.

This series represents a leap forward in backup power technology for the telecom sector. Operators now have access to a solution that ensures their infrastructure remains powered, even under the most extreme conditions, without the burden of frequent battery replacements or the anxiety of faltering power in critical moments. The introduction of the TEL-HT Series marks a pivotal moment in the ongoing quest for more sustainable and efficient energy storage solutions, setting a new standard for reliability and cost savings in the telecom industry.


The core innovation lies in the MSE Pure Lead technology, which enhances the battery’s endurance and efficiency, especially in high-temperature environments. This technology enables the battery to require lower float currents, which in turn slows grid corrosion—a common ailment of traditional VRLA batteries. This significant reduction in corrosion rates directly translates to less water loss and allows the TEL-HT batteries to safely operate at higher temperatures, extending their design life considerably.

Moreover, the TEL-HT Series benefits from optimized grid alloys and the True Front Access® terminal design. These innovations contribute to the battery’s longevity and reliability by ensuring that each cell within the battery can withstand the rigors of extended use in extreme conditions without the performance degradation typical of conventional batteries. The meticulous attention to quality at every step of the manufacturing process further ensures that each TEL-HT battery meets the highest standards of durability and performance.

The combination of these technologies results in a battery that not only lasts longer but also supports sustainability goals through its efficient operation and reduced maintenance requirements. The TEL-HT Series stands as a testament to C&D Technologies’ commitment to innovation, delivering a product that addresses the telecom industry’s need for reliable, cost-effective, and long-lasting backup power solutions.

Key Benefits

The TEL-HT VRLA batteries offer compelling benefits to service providers, the most apparent being the 20% cost savings. This is made possible by the industry-leading warranty that allows operators to extend their battery replacement cycles by an additional 1-2 years compared to conventional VRLA batteries. The financial implications of this are significant, reducing the total cost of ownership and enabling operators to allocate resources more efficiently.

Furthermore, the TEL-HT Series’ ability to deliver twice the battery life of standard VRLA batteries is a game-changer. The MSE Pure Lead technology’s lower float currents not only extend the operational lifespan of the batteries but also halve water loss and diminish grid corrosion. As a result, the TEL-HT batteries boast an impressive design life of over 10 years, more than doubling the industry standard. This extended lifespan is particularly beneficial in applications where battery replacements are logistically challenging or costly.

The wide operating temperature range of the TEL-HT Series ensures reliable performance in extreme climates, from the coldest winters to the hottest summers. This versatility makes the batteries ideal for a wide range of telecom applications, including remote or uncontrolled environments where maintaining optimal battery temperatures can be difficult.

Lastly, the TEL-HT batteries are designed with True Front Access and utilize patented Extrusion Fusion Weld technology, which significantly reduces potential points of failure and maintenance needs. This not only enhances product reliability but also aligns with the operational needs of telecom service providers, who require minimal downtime and maximum performance from their backup power solutions.
