APC UPS Recalibration
Wednesday, 25 October 2017 | Mike
After replacing the batteries in an APC UPS, you may find that the UPS still indicates that the batteries need replacing; the solution is to carry out a run-time recalibration - here's how.
The problem here is when your UPS still indicates that the batteries neeed replacing even after you have fitted brand new batteries. From experience this happens if the UPS has not been used for a long time or if the previous batteries were particularly old or in poor condition.
The best way to carry out a run-time recalibation is by using the Network Management Card (if installed) and/or APC's PowerChute UPS Management Software, which is available as a free download from the APC website.
For newer Smart-UPS "SUA" and "SM" models these are the only ways that the unit can be recalibrated; older Smart-UPS "SU" models can also be manually recalibrated using the following procedure:
The UPS run-time recalibration is now complete
