The APC Battery Backup is an Outstanding Product

We've been using APC Battery Backup Units since we got our first computers in 1997. This was a replacement backup unit for my original APC Backup Unit that we bought in 1997. We live in Florida, where there are many brownouts as well as many power failures. The APC Battery Backup Unit has always come to the rescue. If there's a short power failure, the computers and TVs remain on; if there's an extended power failure, there is enough time to safely shut down the computers and TVs. Also after several years of use, rather than buying a new unit, you can replace the battery and it's extremely easy to do so. Overall, it's an outstanding product.

APC Back-UPS CS 500VA Tower UPS performance.

This is a neat little power backup that takes care of power continuity. Each time there is a power outage, or more frequently a power "downage" it lets you know by displaying a red signal and doing a squeak signal. As soon as power is returned to normal, so does the display return to its usual green. I leave the unit on permanently.
