Abstract

A method of operation includes receiving, by a power supply with battery backup, a battery test command from a user interface on a remote device, switching the power supply to the battery backup in response to the battery test command, monitoring voltage and discharge current of the battery, determining that the battery has reached a threshold capacity due the battery discharge, terminating the battery discharge test and switching the power supply off of the battery backup. The battery backup test command received may be a one-click selection input at a user interface on the remote device where the battery test command is sent to the power supply in response to the one-click selection input. An apparatus that performs the method of operation is also disclosed.

comparing the monitored voltage and discharge current of the battery with battery specification data; and

determining that the battery has reached the threshold capacity based on the comparison.

4. The method of claim 1, where receiving the battery test command by the control and access logic from the user interface on the remote device, comprises:

receiving the battery test command by the control and access over a network connection.

5. The method of claim 4, where controlling a switching unit to switch the external load from the AC-to-DC power supply to the battery backup in response to the battery test command, comprises:
