Lifeline Batteries have earned global recognition as a premier choice in sealed Absorbed Glass Mat (AGM) battery technology. Renowned for reliability and performance, professionals across a wide range of industries have experienced firsthand the superior quality and success of the Lifeline product line.
Manufactured in West Covina, California, Lifeline Batteries are proudly built by Concorde Battery Corporation—a U.S.-based, family-owned and operated company. Lifeline’s technology is directly derived from Concorde’s aerospace-grade batteries, which are trusted by numerous branches of the U.S. military and a broad spectrum of industrial and private-sector applications.
A Heritage of Excellence
From its inception, Concorde Battery Corporation has remained a family-owned, hands-on manufacturer with a legacy rooted in craftsmanship and innovation. Over three decades ago, two hardworking families began producing lead-acid batteries from the ground up—initially serving the aviation sector. Through years of innovation in materials and battery chemistry, Concorde established itself as one of the industry’s top-tier battery manufacturers. Today, the company produces multiple premium brands, serving diverse industries around the world.
AGM Battery Leadership
With the rise of AGM battery technology in the 1980s, Concorde quickly transitioned from producing flooded and gel batteries to pioneering AGM solutions. The company remains one of the most respected AGM battery manufacturers worldwide.
Concorde’s commitment to quality sets its AGM batteries apart. Key innovations include a proprietary lead-oxide paste, fully sealed polyethylene separators (preventing common failure points), and robust, accessible inter-cell welds for easy inspection—features rarely found in mass-produced alternatives. These precise manufacturing techniques ensure that Concorde’s batteries deliver unmatched performance, durability, and reliability.
In addition to aviation, mobility, and solar markets, Concorde has engineered industry-leading AGM batteries for the Marine and Recreational Vehicle (RV) industries—marketed under the Lifeline brand. Concorde also offers high-performance batteries for auto racing and other demanding applications. For more than 20 years, Lifeline has become synonymous with premium-quality AGM technology.
Made in America. Built for Performance.
Lifeline Battery distribution, marketing, and customer support are managed by members of the founding families from two U.S. locations—North Carolina and the corporate headquarters in San Dimas, California. The exceptional performance of Lifeline Batteries in the marine and RV markets is no coincidence: they are built using the same precision manufacturing processes and aerospace-grade materials used in Concorde’s aviation batteries. Like their aviation counterparts, Lifeline batteries are also supplied to multiple U.S. military branches.
Deep-Cycle Innovation for Demanding Applications
Lifeline Batteries has led the way with innovations like the first AGM L16 battery for marine and RV use. With an ever-expanding lineup of group sizes and configurations, Lifeline continues to provide dependable, deep-cycle power across marine, RV, mining, oil and gas, photovoltaic, electric vehicle, standby, and backup power industries.
Expanding Operations and Global Reach
To meet increasing demand, Concorde Battery Corporation has expanded its manufacturing capabilities with a second facility in Atlanta, Georgia. With production now on both coasts, Lifeline Batteries is well-positioned to support growing sales in the marine and RV sectors, as well as in a range of other high-performance markets.
With a robust global distribution network, Lifeline Batteries will continue to deliver premium AGM technology backed by aerospace-level engineering, family-driven values, and a legacy of excellence.
