Why Battery Maintenance is Critical in General Aviation

In the world of general aviation, safety and compliance are non-negotiable. Whether you’re a pilot, aircraft owner, or FBO manager, understanding the importance of regular lead-acid battery maintenance is essential. Batteries like those from Concorde Aviation play a vital role—and overlooking them could lead to safety risks and regulatory headaches.

Concorde lead-acid batteries are industry-standard for many general aviation aircraft, thanks to their reliability and durability. But even the best batteries degrade if they’re not routinely inspected and maintained.

The Hidden Powerhouse: Why Your Battery Deserves Attention

While often overlooked compared to engines or avionics, the battery is the unsung hero of your aircraft. From engine starts to powering emergency systems, a healthy battery can make the difference between a safe flight and an emergency situation.

Yet, many battery failures occur not because of age, but due to neglect. Lead-acid batteries, like those manufactured by Concorde, are robust—but only when properly maintained.

Regular Battery Testing Should Be Part of Every Maintenance Schedule

Regular maintenance of aviation batteries offers several key benefits:

1. Ensure Flight Safety

Avoid the risk of in-flight electrical failures or failed engine starts with consistent testing.

2. Extend Battery Life

Scheduled maintenance prevents over-discharge and sulfation, improving battery longevity.

3. Meet FAA/EASA Compliance Requirements

Regulatory bodies like the FAA and EASA mandate specific testing intervals and performance benchmarks for onboard batteries.

4. Save on Long-Term Costs

Detecting early signs of battery degradation avoids emergency replacements and unscheduled downtime.
