When it comes to aircraft batteries, reliability isn’t optional—it’s critical. You need a battery that cranks strong, lasts long, and is ready when you are. That’s why pilots, mechanics, and fleet managers trust Concorde Battery’s Sealed Lead Acid Batteries (SLABs) to deliver maintenance-free performance under the toughest conditions.
At Aero-Mach Wilco, we’re proud not just to stock Concorde batteries—but to maintain them to exact factory specifications. When you order from us, your battery arrives charged, inspected, and flight-ready—never sitting forgotten on a warehouse shelf.
In this guide, you’ll learn:
- How Concorde Batteries work and why charging matters
- How Aero-Mach Wilco ensures battery quality and availability
- Key care tips every operator should know
- Links to deeper resources you can trust
Why Concorde Batteries Are Different (and Better)
Concorde’s SLABs use Absorbed Glass Mat (AGM) technology combined with PolyGuard® separators to deliver rugged, maintenance-free performance. Their unique design locks electrolyte into the AGM matrix, preventing spills and internal corrosion. Unlike NiCd or flooded batteries, a Concorde battery:
- Doesn’t require fluid level servicing
- Is immune to “memory effect” seen in NiCd batteries
- Boasts superior charge retention (low self-discharge)
- Eliminates thermal runaway risk
- Ships non-hazardous under DOT regulations
Their batteries are built to demanding aviation standards, including FAA TSO-C173, MIL-PRF-8565K, and are manufactured under AS9100/ISO 9001 certifications.

How Aero-Mach Wilco Supports Your Concorde Battery Needs
At Aero-Mach Wilco (a division of Aero-Mach), we understand that a battery isn’t just a purchase—it’s a trust issue. That’s why we invest heavily in stocking, maintenance, and education:
- Always In Stock: We maintain a large inventory of Concorde aviation batteries, including popular models like the RG-35AXC, RG-380E/44, and rotorcraft-specific units.
- Top Charging Program: Every Concorde battery in our inventory follows Concorde’s recommended maintenance cycle per Concorde Battery Manual 5-0324. That means monitoring and when necessary, charging to maintain peak voltage and chemical balance.
- Inspections Before Shipping: We perform visual and voltage checks prior to shipment, ensuring you receive a battery that’s fresh and flight-ready—not just sitting on a shelf for months.
What Does This Means for You? You get full cranking power, reliable cold starts, and longer service life right out of the box.
Key Concorde Battery Maintenance Tips (What Every Pilot and Mechanic Should Know)
According to Concorde’s own Aircraft Battery Manual (5-0324), here’s what every aircraft owner and operator should follow:
1. Top Charging Is Essential
Even though Concorde SLABs have a low self-discharge rate, over time voltage can dip below optimal levels if left idle. Batteries should be recharged:
- After 90 days of inactivity at room temperature (70°F)
- After 60 days at elevated temperatures (above 85°F)
- After any period of deep discharge (below 12.5V for 12V batteries or 25V for 24V batteries)
At Aero-Mach Wilco, we adhere to these timelines religiously.
2. Use the Right Charger
Concorde recommends using an approved BatteryMINDer® or constant-current charger with voltage limiters to avoid overcharging. Using automotive-style trickle chargers can damage your aviation battery.
Tip: We can recommend Concorde-approved chargers for any size operator. From single aircraft to MRO facilities, we have the charger to meet your specific needs.
3. Conduct Capacity Tests Annually
Concorde suggests conducting a Capacity Test (Capacity Check) once a year or during annual/100-hour inspections. This ensures the battery can still deliver 85% of rated capacity under load.
Tip: If your A&P can’t perform a certified capacity test, Aero-Mach Wilco can refer you to certified service centers.
4. Avoid Deep Discharges
Repeated deep discharges shorten a battery’s life. Repeated short flights may prevent full recharge after engine start. Additionally using avionics/ground service without engine power could result in a deep discharge. Top-charging in these scenarios will keep your battery at optimum performance levels.
5. Store Batteries Properly
If your battery will be removed and stored:
- Store at full charge
- Recheck and top charge every 60–90 days
Why Buy From a Stocking Distributor Like Aero-Mach Wilco?
Many suppliers simply “drop ship” batteries without maintenance. At Aero-Mach Wilco, you’re getting:
- A freshly charged battery
- Confirmed factory warranty protection
- Expert aviation parts support
- Batteries stored and maintained to OEM standards
