[Nut-upsuser] CyberPower PR3000LCDRTXL2U — battery date reset?
Well, for a bit of devil's advocate - if the battery swelled, it might hace leaked or fumed, contaminating the device and contacts. The safe approach (for their liability, and for end-users' fire hazard really) is to not claim the device is safe to use anymore.
