QUESTIONS & ANSWERS
The Teledyne Gill 7246-20 utilizes absorptive glass mat (AGM) technology, which immobilizes the electrolyte within the battery, enhancing durability and performance. This design reduces internal movement and vibration-related wear, helping maintain consistent electrical output in demanding aviation environments. AGM construction also improves charge efficiency and supports stable operation across varying flight conditions.
Yes, the sealed VRLA design allows the Teledyne Gill 7246-20 to be installed in multiple orientations without the risk of electrolyte leakage. Because the electrolyte is fully absorbed within the battery’s internal structure, it remains secure even during turbulence or unusual aircraft positioning. This flexibility makes installation easier and supports a wider range of aircraft configurations.
The 7246-20 is designed to maintain its charge for extended periods when stored properly, making it suitable for aircraft that may not be used regularly. With a potential shelf life of up to 24 months before installation, it offers flexibility for inventory management and maintenance planning. Periodic voltage checks and proper storage temperatures help preserve battery health and ensure readiness when needed.
For aircraft that are flown less frequently, the 7246-20 offers reliable charge retention and the ability to recover from periods of inactivity when properly maintained. Its design helps minimize self-discharge compared to traditional battery types, reducing the need for frequent recharging. This makes it a practical solution for private operators or seasonal aircraft usage.
The battery is optimized for constant-voltage charging, which helps regulate current flow and prevent damage from overcharging or undercharging. Proper charging practices reduce sulfation buildup and extend the overall life of the battery. This controlled charging approach ensures the battery consistently delivers its rated capacity over time.
The Teledyne Gill 7246-20 includes sealed venting mechanisms that safely release small amounts of gas during operation while preventing internal pressure buildup. This controlled venting enhances safety without requiring routine maintenance. Additionally, the sealed construction minimizes exposure to hazardous materials under normal operating conditions.
The battery is engineered to operate best within controlled temperature ranges, with optimal performance around standard ambient conditions. While capacity may temporarily decrease in colder environments, it typically recovers as the battery warms. Proper temperature management helps maximize performance and extend service life in aviation applications.
Each Teledyne Gill 7246-20 battery includes a unique serial number and manufacturing date, enabling maintenance teams to accurately track usage and service history. This traceability supports better lifecycle management and simplifies compliance with maintenance schedules. It also helps technicians plan inspections, replacements, and documentation more efficiently.
