Concorde Battery Corp. announces TSO approval of the RG-380E/46 battery series. The RG-380E/46 series batteries have more power at the same weight and in the same dimensions as the popular RG® Series RG-380E/44 batteries. This direct replacement supplies 10 percent more power at 46 Ah than the 42 Ah RG-380E/44. When used in the same application, the RG-380E/46 will last longer (due to a lower depth of discharge on engine start), cause less engine wear (due to more cranking power), and provide more essential power in the event of an alternator failure allowing more time to safely land the aircraft.
