How to Test Your Ups Battery Backup


Making sure that your UPS battery backup works properly will guarantee that you don't lose any files or information during a power outage. UPS (Uninterruptible Power Supply) backups vary in the amount of time their batteries will last, but they all should work long enough to be tested.

  • Plug the UPS backup's AC cable into an available power outlet on your wall, then turn the power on. If the power light is not lit, your unit is defective and will not charge the batteries.

  • Charge the batteries for the amount of time stated in your owner's manual. The time can vary greatly depending on the size of your batteries.

  • Press the "Reset" button on the back of the backup unit to reset the internal circuit breaker. This "Reset" button is located on the back or the top of the device.

  • Plug the monitor's AC cable into one of the "Surge Protector & Battery Backup" outlets on the rear of the UPS device, then power it on. Although there may be multiple outlets on the UPS, usually only some of them offer battery power in an outage.

  • Remove the UPS backup's AC cable from the wall outlet. If your computer monitor loses power, the UPS device is not working properly. If it keeps power, the UPS backup is working.
