FAA Certifies Heavy Duty Sealed Lead Acid Concorde Batteries For Citation CJ4

Company Claims 20-40 Percent Increase In Starting Power Over OEM Batteries

The FAA has awarded an STC to Concorde Battery Corporation for the 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 Battery Corporation is recognized and respected worldwide as the manufacturer of premium valve regulated sealed lead acid aircraft batteries. For over 40 years Concorde has supplied stateside and foreign militaries, Concorde is preferred by airframe manufacturers for OE installations and they are chosen for business and general aviation aircraft of all types with hundreds of FAA & international certifications.
