(4) The battery pack for the B406-4 ELT consists of four “D” size lithium manganese dioxide cells
connected in series. In an effort to increase the safety of the battery pack, a number of
features were designed into the battery pack. To prevent the cells from being charged, diodes
are connected across each cell and fuses are connected to the output. See Figure 4. Battery
