Concorde Battery Receives TSO Authorization Under
TSO-C173

In 2007, Concorde Battery Corporation was the first company to apply for and receive TSO-C173 authorization for a series of Valve Regulated Lead Acid (VRLA) batteries. Early in 2008, Concorde Battery received approvals for additional battery models. Concorde continues to conduct testing for TSO approvals on all remaining emergency and engine / auxiliary power starting VRLA battery models.

An FAA Technical Standard Order (TSO) is a Minimum Operational Performance Standard (MOPS) for specified materials, parts and appliances utilized on civil aircraft. When a company is authorized to manufacture a specific part to a TSO standard, it is referred to as TSO authorization and is a design and production FAA approval.

TSO-C173: This particular TSO is for manufacturers of permanently installed rechargeable lead acid and nickel-cadmium aircraft batteries and describes MOPS established by the FAA. Requirements include meeting standards in RTCA Inc. document RTCA/DO-293.

TSO-C173 applies to permanently installed batteries providing power for aircraft equipment including emergency and standby systems and electrical power to start aircraft engines or auxiliary power units. When a battery is marked with TSO authorization that means the battery meets MOPS of the TSO specifications independent of the battery's intended installation on an aircraft. The TSO battery can be installed on an aircraft only after showing that the airworthiness requirements (certification basis) of a specific aircraft model are met by the TSO battery. A separate FAA approval may be required to install the battery on an aircraft.
