battery. 3. T/F. A standard rating used to specify the capacity of a battery is the five-hour discharge rating. Also used are a high rate of Twenty-minute and a discharge rate of Five-minute ratings. 4. T/F. Nickel-cadmium batteries have become popular in the past few years because of their ability to accept high charge rates and to discharge at equally high rates without the voltage drop associated with lead acid batteries. 5. T/F. Nickel-cadmium is less expensive and easier to maintain than lead acid batteries, that’s why the airliners use Ni-cad batteries. 6. T/F. Nickel-cadmium batteries are more susceptible to low voltage drops during cold weather, than lead acid batteries. 7. Because Ni-cad batteries’ are subject to a condition of “thermal run-away,” The FAA requires manufacturers to have systems that monitor the condition of the battery, when installed on aircraft. 8. T/F. Deep cycling is a condition whereby maintenance personnel discharge a Ni-cad
