My UPS shows "Alarm # 68 Battery DC over voltage" and website shows "UPS hardware fault detected". It hasn't any alarm sound. Could we try to reload the UPS to check the alarm to exist or not? For reloading, would the UPS still provide power to the hardware devices? Thanks.

"Alarm #68 Battery DC Over Voltage" on the Eaton 9910 UPS indicates that the battery voltage has exceeded the maximum allowable limit. In response, the UPS disables the charger until the next power cycle. Reloading (power cycling) the UPS may clear the alarm, but it could interrupt power to connected devices, depending on the UPS's mode and load support status.
