Concorde Battery Corporation Introduces FAA Certification to Install Concorde Batteries on Gulfstream G350/G450

Gulfstream G350 and G450 operators now have a second battery option available by using Concorde STC ST00890DE. The FAA STC approves installation of Concorde’s Platinum Series® RG-380E/46L sealed lead-acid batteries in place of original equipment lead-acid batteries.

This installation does not apply to Gulfstream ASC 069 aircraft equipped with nickel-cadmium batteries. 

The upgrade to Concorde's RG-380E/46L (24V, 46Ah) valve-regulated sealed lead-acid batteries offers Gulfstream operators the reliability of a proven Concorde battery. The RG-380E/46L has been trusted as a robust and reliable battery by the United States Air Force, having served as the main power supply on the C130 for the last five years.

The RG-380E/46L is a fully sealed lead-acid battery. No additional maintenance is required beyond periodic capacity checks to assure airworthiness. Concorde batteries do not require re-blocking and do not require any internal maintenance. STC ST00890DE employs a battery tray insert that couples with the existing battery tray to accommodate the RG-380E/46L batteries without modification to the airframe, so batteries can be used interchangeably.  

Also included with the STC are temperature sensors to mount on each battery. Concorde’s temperature sensors are external components that are transferable from one battery to the next, reducing battery-replacement costs.

Concorde batteries are available worldwide through its authorized distributor network. Visit to find a nearby distributor.
