Concorde Battery received FAA STC approval for its “advanced” lead-acid RG-390E/30 battery on the Cessna Citation Mustang. This replaces the OEM battery with a 30-ampere hour drop-in replacement that is five pounds lighter.

According to Concorde, direct replacement of the OEM battery with the RG-390E/30 “offers benefits of prolonged service life and extended maintenance intervals as a result of enhanced plate design and a proprietary PolyGuard separator system.” High cyclic operations, which are susceptible to early battery wear out, will realize longer life as a result of upgrading to the RG-390E/30, the battery manufacturer said. Additionally, the design extends the inspection interval with initial inspection required at 12 months or 1,000 hours in service and subsequent capacity tests at six months or 500 hours, when initial capacity exceeds 90 percent.

Concorde said that its Platinum-series batteries, which include the RG-390E/30, have a history of dependable starting performance in temperatures ranging from -40 degrees C to 71 degrees C, longer battery life and extra reserve capacity.
