RE: UPS battery low
Is this a large system? What does the user manual indicate regarding battery voltage?
RE: UPS battery low
Battery type and chemistry?
Cell size?
Number of cells?
Normal float voltage?
This battery test that you did: Exactly what did you test and how did you test?
Something else not clear to me: What is the relationship between a "Naster UPS" and a "Slave UPS?
