We want to remind you to test your UPS or Battery Backups. Since your UPS uses a battery, that battery is subject to the same wear and tear as any other battery. As such, the battery, or entire UPS may need occasional replacement. The function of your UPS is to give you enough time to properly shutdown your system during an unexpected power outage, as well as provide constant power during power fluctuations. Additionally, the UPS also provides for a surge protection and line conditioning.
