A battery gets discharged because:

  • The energy required by the load during the time that the load is switched on exceeds the energy stored in the battery
  • The battery's condition is such that it cannot convert all its stored energy into electrical power to support the load.

Ground, or earth, is a system of safety conductors, designed to operate the circuit protective device(s) and disconnect the circuit from sources of power in the event of a fault downstream of it.
