Abstract
Methods, systems, and computer program products determine a battery needs replacement. A power supply utilizes a backup battery to provide backup electrical power. At some point, though, the backup battery becomes inadequate. When the backup battery cannot provide a desired duration of backup operation, an indicator is activated to recommend replacing the backup battery.
