RG-35AXC – Concorde Sealed Battery
Available now on the Airparts.aero Marketplace.
Overview
The Concorde RG-35AXC is a premium, maintenance-free, Recombinant Gas (RG®) sealed lead-acid battery, part of Concorde's renowned Platinum Series®. This 12-volt battery is engineered to provide superior starting power and reliable essential/standby power for a wide range of general aviation piston aircraft. Utilizing advanced Absorbed Glass Mat (AGM) technology, the RG-35AXC offers a high-cranking, non-spillable, and aerobatic-capable power source that eliminates the servicing requirements of traditional "wet" cell batteries. It is a direct, high-performance replacement for numerous OEM batteries, making it the top choice for discerning aircraft owners seeking reliability and peace of mind.
Key Features
- Recombinant Gas (RG®) Technology: A Valve Regulated Lead Acid (VRLA) design where oxygen and hydrogen gases produced during charging are recombined to form water within the battery. This eliminates the need for water replenishment and makes the battery truly maintenance-free.
- Absorbed Glass Mat (AGM): The electrolyte is fully absorbed into a matrix of microfiber glass mat separators. This spill-proof design allows the battery to be mounted in any orientation and renders it safe for aerobatic flight without the risk of acid leakage.
- Superior Cranking Power: The low-impedance design, with tightly compressed plates and heavy-duty intercell connections, provides higher voltage under load than traditional flooded batteries. This results in faster, cooler engine starts and less wear on the starter motor.
- Exceptional Durability: The AGM construction provides superior resistance to shock and vibration, as the plates are rigidly supported and cannot shed active material, a common failure mode in flooded-cell batteries.
- Ready for Installation: Shipped fully charged and factory-tested to assure airworthiness. As a sealed, non-spillable battery, it is exempt from HAZMAT shipping regulations.

The key to the Concorde RG-35AXC's performance is the Recombinant Gas (RG®) cycle within its sealed, Valve-Regulated Lead-Acid (VRLA) design. During charging, electrolysis of water can occur, producing hydrogen at the negative plates and oxygen at the positive plates. In a traditional "flooded" battery, these gases are vented overboard, resulting in water loss. In the RG-35AXC, the AGM separators are intentionally not fully saturated with electrolyte, leaving open pathways. Oxygen generated at the positive plate travels through these pathways to the negative plate, where it reacts with the newly formed lead and sulfuric acid, effectively "recombining" to form water (
2Pb+O2+2H2SO4→2PbSO4+2H2O
). This process prevents water loss, allowing the battery to be sealed and maintenance-free.
Note: This battery is not designed or intended for turbine aircraft engine starting applications. While maintenance-free, regular capacity checks are recommended as part of the aircraft's maintenance schedule to ensure continued airworthiness. Always use a temperature-compensating aircraft battery charger/maintainer to ensure maximum battery life.
