LEAD ACID MAIN BATTERY
Installation of Concorde RG-350 or RG-355 24V 17Ah Valve Regulated Sealed Lead-Acid (VRSLA) aircraft battery as Main Battery in place of the original Nickel-Cadmium battery.
The change introduces a direct replacement of existing SAFT batteries installed in AS350 helicopters without the need to perform any structural or electrical modification.
Concorde valve regulated sealed recombinant gas (RG) Turbine Starting RG-350/RG-355 aircraft batteries, FAA TSO-C173 approved, are contained in a fully sealed aluminum container, avoiding spillage, fitted with silver plated brass M8 terminals. Concorde Platinum Series batteries have been proven reliable, durable and safe in turbine aircraft applications for more than two decades.
The Valve Regulated Sealed Lead-Acid design of the battery avoid the need of any water replenishment, requiring lower maintenance than the original Ni-Cd batteries.
RG-350 and RG-355 are electrically identical and features different container dimensions to fit the different attachments of the different types of the original AS350 Nickel-Cadmium batteries.
