Re: APC Smart-UPS float voltage experiment



Yes, I can agree that "if it ain't broke, don't fix it". Probably some of the components on the board have drifted over the past 13 years and that's why it's "off". Thank you for the info!...

It will go 30 - 35 minutes without much of a problem. I guess, as was suggested, that I will leave it alone for now. Thanks for the response....

Re: APC Smart-UPS float voltage experiment

Hello to all from a new user. I have a 1999 vintage SU2200 that I'd like some help with. The battery charger never seems to make it to 100% and hovers around 94% - 96%. I, therefore, cannot run a runtime calibration test which I'd like to be able to do. I've tried different sets of batteries, old and new, with the same effect. Other than that the unit appears to function normally. I also have a NMC card installed so that I can look at the UPS via the web interface. Any help or guidance would be greatly appreciated! Thanks and advance!
