What is wrong with lead acid battery backup? Seems to be exceedingly stable from my experience. We have all our equipment on -48V DC and have never had a power interruption at any site.
The requirements here are 48 hours of backup by law. Telecom is declared to be part of emergency and defense, so they put in a requirement for resilience.
