1. A system, comprising:

  • a power data computing apparatus configured to receive power outage data associated with a plurality of customer sites;

    a discharge time computing apparatus configured to receive, from each of the plurality of customer sites, discharge time data associated with a battery via a network and calculate a mean discharge time based on the discharge time data wherein the discharge time data is automatically output to the network for receipt by the discharge time computing apparatus when a power loss occurs; and

    a faulty determination computing apparatus configured to compare the discharge time data associated with each battery to the mean discharge time, determine that each battery that is associated with discharge time data that indicates a discharge time value that is less than the mean discharge time is faulty, and output a data signal that indicates that a battery is faulty.
