Incorrect UPS timeleft

Hello.
I have APC CS 500 UPS, RBC17 battery, Unraid 6.8.3. I replaced old 7ah battery with new 9ah battery. Also I made a calibration in apctest utility. But now apcupsd reports incorrect timeleft value. Before replacement I have 6-7 mins under 200 watts load but now I have only 4 mins under the same load. Battery is larger, is newer but timeleft has become less. How this can happen?
