Concorde Battery Corporation has received Technical Standard Order, TSO-C173a, authorization for the RG24-15, RG24-15M, and RG24-16 13.6 family of sealed lead acid batteries. The authorization confirms the batteries meet the Minimum Operational Performance Standards (MOPS).
The batteries undergo rigorous testing, ensuring optimal performance on a fixed wing aircraft or rotorcraft in the most extreme on-board environments, according to company officials.
The approval guarantees the batteries meet MOPS minimizing the testing involved with incorporating the batteries into new type designs, STCs or individual type certified aircraft by way of field approval.
The lead acid battery is today, as it was in the 80’s, the low cost OEM battery that was used to control low cost benefits to the OEM. Many, if not most of the initial purchasers of the airplane, will at a much greater price, but improved life and reliability, change to a bettery battery.
What goes around, comes around.
I was Director of Engineering for Learjet back in the 80s and we did the same thing.
