The RG-390E is a Concorde® Platinum Series® Aircraft Battery. The Platinum Series® is comprised of premium hand made AGM Aircraft Batteries with excess power for many applications. The recombinant gas RG® Series VRLA-AGM batteries are known for superior starting power with quick, cool operation in all conditions without the threat of thermal runaway. Less initial cost than NiCd, no deep cycling, and maintenance free design reducing operating costs per hour. Concorde recombinant gas valve regulated lead acid batteries for engine starting, emergency / essential power, and standby power applications are constructed with cutting edge Absorbed Glass Mat (AGM) technology. Concorde’s proprietary PolyGuard™ Microporous Polyethylene Separator shields the positive plates against shorting, shock or vibration. No other manufacturer offers this dual layer insulation protection feature.
