The front of the battery backup will usually have a power switch to turn the device on and off and will sometimes have one or more additional buttons that perform various functions. Higher-end battery backup units will also often feature LCD screens that show how charged the batteries are, how much power it's using, how many minutes of power are left should power be lost, etc.
The rear of the UPS will feature one or more outlets that provide battery backup. In addition, many battery backup devices will also feature surge protection on additional outlets and sometimes even protection for network connections and phone and cable lines.
Battery backup devices have varying degrees of backup ability. To determine how powerful a UPS you need, first, use the OuterVision Power Supply Calculator to calculate your computer's wattage requirements. Take this number and add it to the wattage requirements for other devices you'll plug into the battery backup. Take this totaled number and check with the UPS manufacturer to find your estimated battery runtime when you lose power from the wall.
