I have a Strata vie system with 12 phones, gate opener and doorphone and it is working great. I have it on a UPS. The KSU had probably been unplugged for many years before this KSU was installed for me. I feel that the 3V memory battery is probably not to be trusted. I have not found anyone in the Dallas,TX area that wants to replace the battery - which I understand.

I have read on this board, that with other systems, 2 12V gel batteries could be wired in series to provide longer memory protection than a UPS. Can this be done with my system? I don't see anywhere on the KSU or the internal power supply to connect battery power via a cable. I do not care about keeping the system operable during a power outage, but would like to keep the programming intact for when the power returns.

I welcome any advice. Thanks so Much!!
