Concorde Battery Announces FAA Approval for Cessna Sovereign 680

The Federal Aviation Administration issues supplemental type certificate (STC) ST04366AT to install Concorde’s RG-380E/60L or RG-380E/53L AGM sealed lead-acid batteries in Cessna 680 aircraft. The Sovereign has now joined the list of Citation aircraft certified to fly with Concorde’s robust RG® Series batteries.

ST04366AT allows for two RG-380E/60L (48 Ah) or two RG-38E/53L (53 Ah) AGM sealed lead-acid batteries to replace the original equipment nickel-cadmium batteries, resulting in 20-40% more battery capacity per aircraft without airframe modification. A temperature sensor kit, part number 5-0121, is included with the STC for each battery.

Concorde has a proven history of success in Citation aircraft. RG Platinum Series batteries perform as well or better than nickel-cadmium batteries and are maintenance-free, requiring no water replenishment, deep cycling or replacement parts and cells. Upgrading to Concorde batteries also reduces down-time and provides a more economical option through lower acquisition cost and reduced maintenance.

Concorde batteries are shipped fully charged and tested. They are Hazmat exempt and are 100% recyclable.

Concorde Battery Corporation is the lead-acid aircraft battery chosen by airframe manufacturers and end users alike due to industry-leading standards of excellence in safety, reliability and longevity sustained over 40 years in business. Concorde is committed to providing the highest quality lead-acid battery solutions and world-class customer support.
