Battery calibration key / constant for Smart-Ups 1400 RM

This was originally posted on APC forums on 8/7/2018


I put new batteries in my SU 1400 RM and discover that my UPS incorrectly shows batteries discharged after a a few minutes.  I found the EXACT same symptoms and cause and solution on the forums, and the solution was to enter a new constant for the batteries (calibration key)

I also found the instructions online for how to adjust the constant using a serial terminal.  Now I just need the value to set the constant to.

Could you post the battery constant / calibration key value I should use for the Smart-UPS 1400 RM ?

You can do a manual calibration. Load the UPS to 30% or more (ie, 285W or more for your UPS), make sure the battery is charged 100%, unplug it, and let it run until it turns off.
