| The term “C or fraction of this term (e.g. C/2) |
|
Describes the current for either charging or discharging a battery and is numerically equal to the rated capacity in ampere-hour (Ah). Therefore, to charge a manufacturer’s cell or battery rated at 20 Ah at C/2 would be to charge the cell or battery at a current of 10 A. “C” is also the rated capacity, in ampere-hours (Ah), obtained when a battery is discharged from a full state-of-charge (SOC), the Cell and Battery Manufacturer’s recommended end-of-charge voltage, to an average cell discharge voltage of 3.0V/Cell at a C/2 rate at 20°C. The actual measured capacity, “C”, will be greater than 20% of the manufacture’s nameplate capacity. All capacities will refer to rated capacity. |

|
| Catastrophic |
|
(1) A hazard that could result in a mishap causing fatal injury to personnel and/or loss of one or more major elements of the flight vehicle or ground facility. (2) A condition that may cause death or permanently disabling injury, major system or facility destruction on the ground, or loss of crew, major systems, or vehicle during the mission. |
