A battery backup, also known as an uninterruptible power supply (UPS), is a device that provides backup power and consistent electricity to a computer system. These batteries ensure that the computer system keeps running even when power from the wall outlet is no longer available.
Understanding Battery Backups
Battery backups come in different shapes and sizes. Most commonly, they are rectangular and freestanding, designed to sit on the floor near the computer. The front of the battery backup usually has a power switch and sometimes additional buttons that perform various functions. Higher-end units often feature LCD screens that show how charged the batteries are, how much power the unit is using, and how many minutes of power are left should the power be lost.
The rear of the UPS features one or more outlets that provide battery backup. Many devices also feature surge protection on additional outlets and sometimes even protection for network connections and phone and cable lines. The battery backup sits between the utility power and the parts of the computer, with the computer and accessories plugging into the battery backup and the battery backup plugging into the wall. 1
Choosing a Battery Backup
There are several popular manufacturers of battery backups, including APC, Belkin, CyberPower, and Tripp Lite, among others. When choosing a battery backup, consider the power requirements of your computer system and the amount of time you would need the backup power to last.
Some battery backup systems may seem pointless because they only supply a few minutes of power. However, with even five minutes of extra power, you can safely save any open files and shut off the computer to prevent damage to hardware or software. 2 With the computer attached to an online UPS, a power outage may even go unnoticed because the battery will provide the power before, during, and after the power break.
Power Options in the Operating System
Battery-powered devices can behave differently than desktop computers. This distinction is due to built-in power options in the operating system. If your laptop has ever gone to sleep or shut down on you after you’ve stopped using it for a while, but only when it’s not plugged in, you’re familiar with these power options.
Battery Backup Maintenance and Replacement
Battery backups are cumbersome due to the batteries located inside. These batteries are, however, often replaceable. Regular maintenance and timely replacement of batteries ensure the long-term effectiveness of the battery backup.
Battery Backup and Solar Power Storage
Battery backups are not only useful for computer systems. They have found wide application in renewable energy systems, particularly solar power storage. Residential solar battery storage allows homeowners to store excess solar energy for use during power outages or during peak power usage times.
