Aircraft batteries are often the unsung heroes of the fleet. Buried deep in the avionics bay, they are essential for engine starts, APU operations, and emergency power, yet they frequently receive less attention than engines or landing gear. However, neglect here is costly. A premature battery failure can ground an aircraft instantly, turning a standard maintenance check into a high-priority AOG (Aircraft on Ground) emergency. This is why specialized care for lead-acid batteries, specifically the Gill and Teledyne series, is critical for operational reliability.
Many generalist MROs treat battery maintenance as a side task, often lacking the specific infrastructure to perform deep-cycle capacity testing accurately. At Skybase MRO, our C5-rated electrical shop is designed specifically for this purpose. We don’t just “charge and go.” We follow rigorous OEM procedures to test the true health of the cells. By performing precise capacity checks and reconditioning cycles, we can often restore a “failing” battery to full serviceability, saving operators the significant cost of purchasing new units prematurely.
Furthermore, proper maintenance impacts more than just the battery itself. A weak battery puts unnecessary strain on the APU and engine starters, forcing them to work harder to turn the engine. Over time, this can lead to expensive failures in those critical systems. Our technicians use advanced analysis tools to detect cell degradation early, allowing for proactive planning rather than reactive panic.
It is also a matter of compliance. Modern aviation batteries have strict regulatory requirements regarding their maintenance intervals and capacity thresholds. Flying with a battery that hasn’t been properly “capacity tested” (not just voltage checked) is a regulatory violation that can lead to audit findings. Our DGCA-approved shop ensures that every battery we release comes with a complete history and a valid Authorized Release Certificate (Form 1).
Ultimately, treating your batteries as a managed asset rather than a disposable commodity is a smart financial strategy. It reduces your spares consumption, lowers your emergency shipping costs for hazardous goods, and ensures your aircraft starts the first time, every time.
