This Concorde Battery is TSO Approved under FAA TSO C173 Aircraft Batteries. TSO Approved authorizes Concorde Battery to produce a part to a Technical Standard Order. TSO Approved is both design and production approval of the battery.

Emergency Battery for lighting, standby, back up power, avionics and FADEC. Protects and extends the life of other avionics. Concorde's Emergency Batteries float directly on the DC buss with no need for a dedicated charger. This results in a high inrush current which extends battery life with fast recovery time from discharge. With the battery floating directly on the buss, transient spikes in the DC power are absorbed. These batteries are self regulating on charge and will take only the current required to maintain it at full charge.

Recombinant Gas - The RG® Series are low resistance, valve regulated lead acid (VRLA) batteries.
