MFR Model# RG-220


Concorde’s higher capacity turbine starting sealed lead acid RG-220 (24V, 21Ah) batteries replace Gill’s G-246AT / G-246 / PS12-24P-11 (24V, 19 Ah) or 7246-20 (24V, 20 Ah). The TSO-C173a authorized RG-220 was specifically designed to start PT6 turbine engines. It is built with the same components and features that are proven to optimize current output, maximize capacity and sustain turbine engine power requirements in the most demanding jet applications. The RG-220 is dependable season after season. Upgrading to the RG-220 results in faster starts, improved performance and reduced engine wear.
