cVoIP Battery Backup Unit


Natural and man-made power disturbances can disrupt the power supplied to your home electronics. These problems can disrupt the normal operations of important electrical equipment and related services. Battery Backups provide an uninterruptible power supply (UPS) to keep critical systems up and running in the event of a power loss. The RG Battery Backup has been designed to maintain your AT&T U-verseSM Voice service in the event of a short disruption to your commercial power service. Belkin warrants to the original purchaser of the Belkin RG Battery Backup, for a period of 3 years from the date of installation, that the RG Battery Backup shall be free of defects in design, assembly, material, or workmanship, and will repair or replace, at its option, any defective RG Battery Backup free of charge.
