About this product
The AD‑2758 is a 24‑volt nickel‑cadmium aircraft battery assembly. It comprises 20 series‑connected Ni‑Cd cells housed in a welded stainless‑steel container, delivering a nominal capacity of 23 Ah at a 1‑hour discharge rate. Installed as the main battery on an aircraft, it supplies high‑current power for engine and APU starts on the ground or in flight, and provides emergency DC bus power in the event of generator failure, ensuring continued operation of essential flight instruments and controls

PRODUCT DESCRIPTION

AD2758

  • High Energy Density: Delivers 23 Ah of capacity in a compact, lightweight assembly, optimizing aircraft weight and space allocation.

  • Wide Temperature Range: Ni‑Cd chemistry and robust cell design ensure reliable performance from –55 °C up to +55 °C, suitable for varied operational climates and high‑altitude environments.

  • Extended Cycle Life: Engineered for over 1,000 charge/discharge cycles at C/1 rate, minimizing life‑cycle cost and downtime for battery replacements.

  • Maintenance‑Free Sealed Design: Thermo‑welded cells and leak‑proof housing eliminate the need for water topping, reducing maintenance tasks and contamination risks.

  • Supplying emergency DC bus voltage to flight control computers and instrumentation during generator outages.

  • Backing up critical avionics such as flight data recorders and standby attitude indicators.

  • Energizing lighting circuits in electrical failure scenarios.

  • Serving as a ground‑support battery for system tests and maintenance checks.

  • How long can the battery support emergency power?

At a moderate load, it can sustain operations for over two hours before reaching the cutoff voltage.

  • What charging profile should be used?

A constant‑voltage charger set to the OEM‑specified 28 V maximum, with a current limit of 1 C, ensures full recharge in approximately one hour.

  • Is the battery maintenance‑free?

Yes, its sealed, leak‑proof design requires no cell topping or electrolyte checks under normal operating conditions.
