Whether it’s in aviation, telecommunications, healthcare, or data centers, a power failure—even for a few seconds—can cause severe disruption, safety issues, and data loss. Backup batteries serve as the critical link between power outages and operational continuity. Among the most trusted names in the backup battery industry are SECURAPLANE, CONCORDE, and MARATHON. Each offers distinct advantages tailored to specific applications and environments.
Why Backup Batteries Matter
Backup batteries are designed to keep systems operational when the main power source is unavailable. They support everything from emergency lighting and life-support machines to navigation systems and data servers. The right battery must meet various criteria including voltage, power capacity, charge/discharge cycles, and environmental tolerance. This is where SECURAPLANE, CONCORDE, and MARATHON excel with their high-performance and application-specific battery solutions.
SECURAPLANE: High-Performance Power for the Skies
SECURAPLANE, a part of Meggitt, is a major supplier of power solutions for the aerospace industry. Their batteries are engineered to perform under extreme conditions, making them a top choice for commercial aircraft, private jets, and military aviation systems. SECURAPLANE offers both lithium-ion and sealed lead-acid batteries, allowing users to choose based on the energy requirements and weight constraints of their aircraft systems.
One of the defining features of SECURAPLANE batteries is the integration of onboard Battery Management Systems (BMS), which helps monitor cell status, prevent overcharging, and enhance overall battery life. These systems also reduce maintenance needs by allowing real-time diagnostics. Moreover, SECURAPLANE batteries are certified by key aviation authorities including FAA and EASA, assuring quality and safety compliance at the highest levels. Known for their superior temperature tolerance, these batteries can perform reliably in both cockpit interiors and external compartments where conditions vary significantly.
CONCORDE: Rugged, Maintenance-Free Aviation Solutions
Another leading name in the aerospace battery market is CONCORDE Battery Corporation. Based in the United States, CONCORDE has been supplying batteries to both civilian and military aviation sectors for decades. Their Absorbed Glass Mat (AGM) sealed lead-acid batteries are known for high reliability, deep-cycle capability, and superior vibration resistance.
CONCORDE batteries are particularly valued for their maintenance-free operation. There’s no need for fluid refills, and the AGM technology prevents acid spills, making them safer and more convenient for both pilots and maintenance crews. These batteries are used in aircraft from manufacturers such as Cessna, Beechcraft, Piper, and are even integrated into military jets and helicopters.
Designed to function efficiently under harsh operating conditions, CONCORDE batteries also offer excellent cold weather performance. Their long shelf life, resistance to corrosion, and flame-retardant casing make them a preferred choice in aviation environments where reliability and safety cannot be compromised.
MARATHON: Industrial Power That Lasts    
While SECURAPLANE and CONCORDE focus primarily on aviation-grade solutions, MARATHON batteries from Enersys are tailored for industrial and commercial backup systems. These batteries are widely used in data centers, telecommunications networks, uninterruptible power supply (UPS) systems, and renewable energy storage.
MARATHON batteries are valve-regulated lead-acid (VRLA) types, meaning they are sealed, spill-proof, and require minimal maintenance. This makes them ideal for long-duration standby applications where accessibility might be limited. Their design allows for both horizontal and vertical installation, making them versatile in cramped or space-sensitive environments.
One of the strong suits of MARATHON batteries is their high energy density and excellent float service life. They deliver stable voltage output over extended periods and are well-suited for deep discharge recovery. These characteristics are essential in industries like telecommunications and IT, where even milliseconds of downtime can impact business continuity.
How These Battery Brands Compare
Each of these battery brands—SECURAPLANE, CONCORDE, and MARATHON—excels in a different area of the backup power industry. SECURAPLANE specializes in aviation-grade lithium-ion and lead-acid batteries designed for extreme environments and equipped with intelligent monitoring systems. CONCORDE is renowned for its rugged, maintenance-free AGM batteries built for both commercial and military aircraft. MARATHON stands out in the industrial and telecom sectors with its cost-effective, high-capacity VRLA batteries designed for long life and low maintenance.
Choosing between them depends entirely on the intended application. For instance, aviation professionals seeking a lightweight, high-energy battery with built-in diagnostics would benefit most from SECURAPLANE’s lithium-ion line. Those looking for a durable, no-maintenance battery for general or military aviation might prefer CONCORDE’s AGM models. Meanwhile, facilities managers and IT infrastructure planners looking to safeguard critical systems would find MARATHON batteries to be a perfect fit for telecom towers, UPS systems, and server rooms.
Advancing Battery Technologies and Eco-Conscious Solutions
Each of these manufacturers is also taking significant steps toward sustainability and innovation. SECURAPLANE’s lithium-ion batteries offer extended lifecycle performance, reducing the need for frequent replacements and therefore lowering environmental impact. CONCORDE is committed to eco-friendly manufacturing practices and offers recyclable battery components. MARATHON batteries, with their long service life and stable float charge performance, help reduce the carbon footprint of backup systems by minimizing waste and energy loss.
As the world moves toward greener technologies and smarter energy management systems, the role of efficient backup batteries will become even more crucial. These companies continue to innovate, developing products that not only meet today’s standards but also anticipate the needs of tomorrow’s energy infrastructure.
Final Thoughts    
In critical environments where power loss is not an option, the choice of a backup battery becomes a mission-critical decision. Whether you’re managing an aircraft fleet, maintaining essential communications infrastructure, or safeguarding high-value digital assets, selecting the right battery solution from trusted names like SECURAPLANE, CONCORDE, or MARATHON ensures your operations stay secure and uninterrupted.
Each brand brings a unique set of strengths to the table. From the aerospace precision of SECURAPLANE to the military-tested resilience of CONCORDE, and the industrial backbone of MARATHON, these batteries represent the best in class for their respective domains. In a world increasingly reliant on constant power, these backup batteries offer the peace of mind every business and organization needs.
