FAA Certification Approves Heavy-Duty Sealed Lead-Acid 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.

Concorde's sealed lead-acid batteries are the economical solution, with a lower cost of acquisition, reduced maintenance requirements and hazmat-exempt shipping. Concorde batteries never require water replenishment, and there is no threat of thermal runaway. At the end of life, the lead-acid battery is 100% recyclable. 

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