Full charge capacity: Measured in mAH (milliampere-hours), this refers to the amount of power the battery is capable of containing, less the energy required to shut down the device.This number lowers as the battery becomes depleted with usage and age.

Consumed / depleted: Consumable parts are those that deplete over time as their internal components are used.Batteries, due to their chemical components, are considered consumables, and over time they lose their ability to hold a charge.
