Concorde Aircraft Batteries announce higher capacity replacements

Concorde Battery has announced a series of higher capacity replacement batteries for Phenom 300 jets, heavy duty/high capacity replacements on the Citation 525C also known as Citation CJ4, and the Gulfstream G350/G450 Concorde Battery RG Series replacements.

Concorde Batteries for Citation CJ4

Concorde Battery Corporation presents FAA STC SA00944DE for installation of higher capacity sealed lead acid batteries, the RG-380E/60L (24V,48Ah) or RG-380E/53L (24V, 53Ah), in place of the original equipment lead acid or nickel cadmium battery on Textron Aviation’s 525C.  

Concorde developed STC SA00944DE specifically for Cessna Citation CJ4 operators based on reports of higher ITT (Interstage Turbine Temperature) on start than experienced on other CJ models.  These heavy duty battery options provide increased reserve capacity and improved outrush current at start. Starting power and efficiency is increased by 20-40% over the original equipment batteries which has effectively reduced ITT on start.  Additionally, the higher capacity options reduce the depth of discharge which in turn increases overall battery life.

Gulfstream G350 / G450

Gulfstream G350 & 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.

Phenom 300 Operators

EMB505 operators may now install higher capacity Concorde batteries in the Phenom 300 with FAA approved STC SA00959DE and EASA ESTC 10072168 Rev. 1.  These new STCs provide for an option between an RG-390E 28 Ah or RG-390E/30 30 Ah auxiliary battery and an RG-380E/44 42 Ah, RG-380E/60L 48 Ah or RG-380E/53L 53 Ah main starting battery, permitting operators the option to cater battery capacities to unique operational requirements for optimized performance.

STC SA00959DE is an upgrade from Concorde STC SA01703WI which installed only the RG-380E/44 (42 Ah) main and RG-390E (28 Ah) auxiliary batteries.  SA00959DE now provides operators with the option to increase Concorde battery capacity up to 53 Ah.  SA01703WI holders may upgrade to SA00959DE free of charge by contacting Concorde directly for the STC paperwork.
