    Professionally Researched. (What's this?)

    Battery backup units, also referred to as uninterruptible power supplies, provide continuous AC power for computers in the event of a power failure from the electric company. Power can be lost for hours, minutes or just a second, but battery backup systems maintain a seamless supply of electricity.

    Prevention of Lost Data

    A loss of power while you are in the middle of typing a document or doing any work on the computer could mean a loss of what you have done since the last time you saved your file. Even the lowest-priced battery backup units will provide power for several minutes, giving ample time to save your work and shut down your computer.

    Minimizing the Loss of Work Time

    More expensive battery backups can power a computer and monitor for a half an hour or longer, giving you time to continue your work even while electricity to the building is out.

    Hardware Protection

    Surges in electricity, especially when the power cuts out and returns in less than a second, can damage delicate computer equipment. Battery backups react so fast that power remains steady, keeping the units functioning properly.

    Software Protection

    A power outage while that occurs when a hard drive is saving a file or updating its directory can corrupt data on the hard drive, with a loss of that file or possibly even the entire contents of the drive.

    Utility And Data Line Protection

    Some units also safeguard utility and data lines from damaging surges.
