Concorde Battery (Booth B5925) has received an FAA supplemental type certificate (STC) for installation of its lead-acid Platinum series battery in the Sikorsky S-92A. The 17-amp-hour RG-292-102 or 24-amp-hour RG-292-103A, which offer lower operating costs, are a direct-fit replacement for the helicopter’s original NiCad battery.

When replacing the NiCad battery with the Concorde lead-acid battery, the original “temperature sensor connector is capped, bagged, and stowed,” according to Concorde, as it is no longer needed. The lead-acid battery upgrade costs less and the batteries require less maintenance, with no watering requirement and no risk of thermal runaway. The Concorde batteries are also exempt from hazmat shipping regulations.

Another advantage to the Concorde lead-acid batteries is “instant spooling of the engines upon starting,” the company said. “Helicopter operators depend on Concorde batteries for reliability in remote locations and extreme weather conditions, with Concorde-certified performance at temperatures ranging from -40 degrees Celsius to 71 degrees Celsius.”
