Concorde Battery received U.S. FAA supplemental type certificate (STC) approval for installation of the newest addition to its Platinum Series turbine aircraft starting battery family, the RG-41/53, on the Piper M500 and M600.
TSO-C173a approved and eligible for installation in Piper PA-46-500TP and PA-46-600TP aircraft under FAA STC SA01050DE, the heavy-duty 53 Ah lead-acid absorbed glass mat battery provides nearly 40 percent more starting power and reserve capacity, reducing engine wear. In addition, the RG-41/53 reduces the depth of discharge on engine start, resulting in increased battery life, Concorde said.
The West Covina, California-based battery specialist said the sealed lead-acid batteries never require water replenishment, are maintenance-free, and pose no threat of thermal runaway. RG-41/53 batteries, and accompanying STCs, are available through Concorde’s authorized distributor network.
Concorde Battery has supplied aircraft batteries for more than 40 years, counting airframe manufacturers, business and general aviation operators, and U.S. and foreign militaries among its customers.
