Battery Replacement Options
	BP8-U The BP-8U is an external battery pack, designed primarily for use with SEI's DP and PoweRack systems. Backup time is assured with automatic testing of internal batteries.
	S1145B The S1145B is an improved replacement for the Lucent/ATT 114X series of 48 Vdc battery packs. Both the BP8U and S1145B monitor charge status and automatically perform periodic battery tests to guarantee holdover capability.

The ISDN Battery Replacement Program was implemented because SEI recognized hat many ISDN customers were not aware that power for their telephone systems was supplied locally and that the backup batteries of the power system require periodic testing and replacement. Adequate backup battery capacity is needed to insure that minimum standards are met for telephone system disaster preparedness. As part of this program, SEI technicians perform on-site testing of batteries. This service is free of charge for qualified customers. For program details please contact SEI at 800-765-4734.

SEI has now extended the Battery Replacement Program to all enterprise ISDN Centrex users. SEI will provide free telephone consultation and, depending on the number of power systems at the site, a no charge, one-day technician visit to test these systems and provide a status report with recommendations. Many organizations have taken advantage of this visit to train their technical staff on battery maintenance and testing procedures. Contact Scott Clough at SEI, 800-765-4734 (x216), for further information.
