Carl,
I have not worked with a UPS for many years but I was once responsible for building a central office for a security company. It featured a battery back power system capable of keeping the telephone and computer systems online for a few hours. I had them do all the standard logging of the parameters like voltage, temperature, electrolyte specific gravity and so on. I also had an automated system that would transfer operation to the battery bank for 5 minutes once every 24 hours. By monitoring the voltage drops during this test period, I could anticipate the imminent failure of a battery. As for long term predictions, I’m not certain you can do this reliably. There are too many environmental and operational factors involved. Regards, -Doug Doug Powell, Staff Engineer Corporate Compliance Dept.
