New battery, runtime remaining low?

Anonymous user · ‎2021-06-29

Have a Smart-UPS 1000 (sua1000 I believe) and Powerchute Business Edition 9.0.1. We received an alert of insufficient runtime and battery should be replaced - battery was installed in 2010.

Installed a new Battery with the UPS still on and let it charge for a day. Powerchute now shows capacity at 100% and Load at 33% but the runtime remaining is only 10 minutes. Ran a self-test and no change.

Any ideas?

Have you tried running a software run time calibration via the PowerChute Business Edition? If not, I suggest that you try that first and if that didn't help try the manual run time calibration stated below:

1. Battery must be at 100% capacity when the Runtime Calibration is initiated/started.
2. The UPS must have at least a 30% load on it during the calibration.
3. The load cannot fluctuate more than +/- 5% during the calibration.
4. The battery must be discharged to at least 25% capacity (it is best to allow the UPS to shut off due to a discharged battery).

In addition to the above conditions, any UPS monitoring/shutdown software should be stopped from running in the background, and the serial cable should be detached from the UPS. This is necessary in order to prevent the software from shutting down the server/UPS due to an on-battery or low-battery condition.

If these steps wouldn't help, I suggest that you call our Technical Support Team to assist you further and let them know what you have done so far to fix the issue.
