APC Smartups SUA750i - how to Reset the System Runtime afterfitting new batteries

[BillP]

I please need some help:

Fitted new batteries - however the Powerchute runtime calibration fails and the immediately shuts down  the PC.

Device Status:              Battery discharged

UPS Load                   44.8 %

Runtime Remaining      0 Minutes

Battery Status

-------------

Battery Charge             100%

Battery Voltage             28.2V

Nothing that I tried  over the last few days helps.

When I  power a load at +/-40% load value, the UPS takes 30 minutes before it shuts down, this toi me indiactes this is a UPS Calibration issue and not a battery problem.

So you were able to basically already do a manual runtime calibration already according to what I mention below?

Our manual runtime calibration procedure requires you to stop any PowerChute services, disconnect the serial or USB cable from the UPS, and then have a at least 30% load which does not fluctuate more than +/5% (which maybe you did already do this part some what) and then let it run down until it turns off and let it charge up. Is that what you did or what was different?

If it was that procedure already, technical support might be able to provide you with other instructions I cannot really post here but it would be a last resort if the calibration is done properly but not working.

Dear Angela

Thank you for the quick reply.

Leigh (from support)  provided me with the necessary info to do the reset earlier today. 

I have done that  and all is back to normal.

Thanks and Regards
