Concorde Battery Sealed RG-235

The Concorde RG-235 is a Platinum Series® 24 V sealed lead-acid aircraft battery designed for turbine starting and emergency or main starting power duties. Its valve-regulated recombinant-gas (RG®) construction uses absorbed glass mat (AGM) technology for a maintenance-free, non-spillable battery solution.

Manufactured by Concorde Battery Corporation, the RG-235 combines low-impedance battery design with proprietary PolyGuard® separators for added resistance to shock and vibration. The battery is housed in a fire-resistant aluminium container and incorporates an MS3509-conforming quick-disconnect receptacle and lifting straps.
