3-8-2017 - Concorde`s High Capacity RG-427 Now Available for Bell 407 and Bell 427
West Covina, CA - Concorde Battery Corporation is pleased to announce that Rotorcraft Support Inc. of
Van Nuys California has received a FAA STC to install the RG-427, 34 Ah battery, in Bell 407 and Bell 427
Operators have requested a higher capacity battery for the Bell 407 as this helicopter is often used in
high cyclic and short leg operations. In these types of operations, the original equipment 28 Ah battery
is not getting fully recharged causing starting performance during successive engine starts to degrade
and shorten battery life. The decrease in power also causes unnecessary wear on engine components.
Air Ambulance and Oil & Gas fleets conduct some of the highest cycle operations. These operators will
realize an increase in starting power and improved performance after upgrading to the RG-427, 34 Ah,
24 volt battery that is packed with over 20% more power than the 28 Ah battery.
Rotorcraft Support Inc. has added the RG-427 to their FAA approved STC SR01456LA for the Bell 407.
This STC was also upgraded to include RG-407, 27 Ah, and RG-427 installation approval on Bell 427
helicopters. This is the first FAA STC approved for Recombinant Gas (RG®) sealed lead acid batteries in
the Bell 427!
Concorde has supplied lead acid batteries as original equipment and direct replacements for fixed wing,
rotorcraft and unmanned aircraft for decades. Concorde offers over 100 unique batteries installed as
original equipment by the majority of aircraft manufacturers and adopted by military aircraft operators

facility located at the Van Nuys Airport in Southern California. RSI`s helicopter maintenance and
