If I connect a APC Power-Saving Back-UPS Pro 1000, Part Number: BR1000G to my Mac computer using a USB cable, running Mac OS X 10.8, how do I calibrate the battery backup using the UPS service that is built into the operating system?
iMac, Mac OS X (10.6.8)
This doesn't make any sense. There's no need to calibrate the APC unit.
I contacted APC Technical Support at 800-555-2725 and they told me that they have discontinued making the PowerChute Personal Edition software for the Mac and the OS X UPS feature also doesn’t do calibration. They said if I wanted to get the most accurate reading on how much runtime my APC battery backup would provide they recommended that I do a manual calibration. They also recommended that I do a manual calibration once a month or so to help improve battery life.
This seems like a waste of time. Who cares how accurate the reading is? Depending on the machine you have on battery backup, when power fails you'll get between 10 and 60 minutes. You should do a clean shutdown if the power is off for more than 5 minutes.
OS X can tell you how much time you should have on battery backup, if you simply plug the UPS into a USB port.
How do I calibrate a battery backup using OS X 10.8?
