Battery must be at 100% capacity when the Runtime Calibration is initiated/started. (charge the UPS for 24hours prior)<br> 2. The UPS must have 30-34% load on it during the calibration (Constant load, try: lamps, computers, monitors. Measure load % by PowerChute)<br> 3. Disconnect the serial/USB comm cable from the UPS (you don’t want PowerChute to shut down equipment)<br> 4. The battery must be discharged completely (unplug UPS from wall outlet, let the UPS to shut off completely due to a discharged battery).<br>
5. Remove the attached load (ie – lights, computers)<br> 6. Let the UPS charge for 8 hours while OFF (plug back into utility power, press OFF button when UPS turns ON)<br> 7.

</div>I've been in the same situation after replacing the battery in SC620I model.<br>
<br>
Then I found http://old.nabble.com/SmartUPS-and-new-battery-td20678966.html<br>
and followed the procedure:<br>
<br>
1. Shutdown the apcupsd daemon.<br>
2. Run apctest<br>
3. Choose option 6 to enter terminal mode<br>
4. Enter Y (UPS should respond SM)<br>
5. Enter 1 (one, not el; wait 4 seconds)<br>
6. Enter 1 (one, not el; UPS should respond PROG)<br>
7. Enter 0 (zero, not oh; UPS should respond with current constant)<br>
8. Enter + (plus) or - (minus) to increment/decrement the value<br>
9. Enter R to reprogram constant value (UPS should respond Bye)<br>
10. Enter Y (UPS should respond SM)<br>
11. Enter 0 (zero, not oh; UPS should respond with the new constant)<br>
12. Enter Esc to exit terminal mode<br>
13. Choose option 7 to exit apctest.<br>
<br>
The value to store in the register 0 differs by the model. There is a table<br>
posted in the middle of the thread. I hope your model is listed there.<br>
If you cannot find your model, you may want to try experimenting with different<br>
values.<br>
<br>
In my case, after updating register 0, my UPS is back to 42 min runtime.<br>
<br>
Hope this helps.<br>
<br>
