DirJournal's Perspective

Editorial analysis

The company's focus is deep cycle AGM batteries for the solar and photovoltaic industry, a line it has manufactured since 1987. That follows an earlier start in battery manufacturing, which the company dates to 1979 in the U.S.A. Specifications are separated by voltage, with the 12 volt range described apart from the 6 volt and 2 volt ranges. Applications cover grid tied and off grid systems, along with energy storage for backup power and smart grid systems. Terminal options and battery construction are covered alongside battery banks and installations. Certification includes ISO 9001 + AS9100 and FAA Parts Manufacturing Approval (PMA) qualification, and the Department of Defense has received over 150,000 military batteries from Concorde. Management's combined battery manufacturing experience is stated at over one hundred fifty years.
