Nickel-cadmium batteries fill a great need in the aircraft industry today. This battery is far superior to its predecessor, the lead-acid battery, in its ability to provide power for larger electrical loads and/or loads sustained for long periods. Yet, aircraft operators have experienced many unexpected problems with this battery. These problems can be greatly reduced, if not eliminated, through a better understanding by the design engineer of the battery's construction, abilities, and limitations. Further improvements in performance can be accomplished by the aircraft operator through constant and proper maintenance.
