Airlift receives Canadian and Brazilian validation to EASA STC for single and dual lead acid battery installation in AS350

Airlift AS has received TC Canada and Brazilian validation to EASA STC 10044362 allowing for single and dual battery installations of Concorde’s Sealed Lead Acid RG-350 battery on EurocopterAS350B, -BA, -B1, -B2 and B3 models.  The European, Canadian and Brazilian approvals are now available through Concorde Battery Corporation’s worldwide network of distributors. 

Many cold weather andhigh cyclic operators have requested a Lead Acid option for use in Europe andAirlift has fulfilled this request with Concorde batteries. For conversions ona single battery installation STC 10044362 replaces the main 15Ah nickel-cadmiumbattery with either the Concorde RG-350 or the RG-355 17 Ah Lead Acid batteries.If the aircraft has been modified with Eurocopter Service Bulletin 24.00.01(starting in very cold weather) Airlift’s STC allows for the replacement of both Nickel-Cadmium batteries with Concorde RG-350 batteries.   

RG-350 and RG-355 are TSO authorized and as such, have passed rigorous TSO C-173 testing for dutycycle, electrical performance, temperature extremes, shock/vibration and environmental requirements.  Concorde’s valve regulated lead acid (VRLA) recombinant gas (RG®) absorbed glass mat (AGM) technology has been proven as reliable, durable and safe for over 30 years.  Superior performance can be attributed to unique design features such as proprietary PolyGuard®separators (an additional layer of protection against shorting, unique to Concorde) robust plate construction, over the cell wall intercell connections for reduced internal resistance and a commitment to quality standards.  

The advantages of converting from nickel-cadmium to Concorde’s RG® Series batteries include lower cost of acquisition, zero maintenance and reduced battery costs per flighthour. Concorde batteries do not require deep cycling to remove the “memory effects” seen in nickel-cadmium batteries, do not require water or electrolyte replenishment and have no risk of thermal runaway.

With the benefit of RG® Series batteries shipping Hazmat Exempt, transportation is more cost effective regardless of whether shipping by land, sea or air.
