Avionics Battery for lighting, standby, emergency power. Protects and extends the life of other avionics. Concorde 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.
