Do You Have The Correct Battery For Your Flying Schedule?

May 2025

On a regular basis, we get phone calls from operators frustrated that their batteries have not provided the long life that was advertised when they purchased them. A well-maintained battery will provide three to five years of dedicated service, maybe even more. And that premature failure is not a defect or fault on the part of the battery, but rather on the operator for not purchasing the correct battery required for their flying schedule.

We have produced many articles about the care and maintenance of aircraft batteries. Here’s one about cold storage, and another about maintenance & charging. 

Operators often don’t think about their aircraft’s batteries unless they require maintenance or do not operate as expected. However, this critical component deserves to be taken more seriously. Think about it. The batteries are the first component to engage an aircraft’s electrical system and the last line of defense before everything shuts down in an emergency.

All three of Duncan Aviation’s battery shops have every test set, battery charger, and capacity gauge available to perform capacity checks, testing, and maintenance for every aircraft battery in service on today’s business and general aviation aircraft, along with dedicated rooms for both lead-acid and NiCad battery services.

Inspection, maintenance, repair, and exchange capabilities on:

• A123

We have access to over 50 PMA (Parts Manufacturing Authority) and STCs (Supplemental Type Certificates) that apply to more than 250 battery part numbers.
