410946 Saft Batteries® 24V Ni-Cad Aircraft Battery

Overview

The 2758 Saft nickel-cadmium battery consists of a stainless steel box (020), containing 20 individual cells VHP230KA-3. These cells are connected in series to obtain 24 V nominal. Individual cells are enclosed in a container that provides insulation, allowing them to be fitted side-by-side in the battery box. Interconnection of cells is via rigid, highly conductive, nickel-plated copper links (270 to 310). Each link is held in place by nickel-plated copper nuts (350) on the cells’ terminals. Inside the battery box, individual cells are held in place by partitions, liners and spacers (130), and a cover complete (050). The connector (200) connects the battery to the aircraft DC power.

ALL NICAD BATTERIES ARE UNCHARGED
