Battery’s life may be different depending on the conditions of blackout time, service temperature, etc.
Battery can be charged when power is on, and be used for RTC function.
If the battery voltage is discharged below 2V due to not using the PLC for a long time, the battery may
not be charged. Recharge within 6 months (when stored at 25℃) after fully charged. If the battery is not
charged, replace the battery through a service center. In this case, the PLC clock must be set again, but
the program and backed up data are maintained and preserved regardless of whether the battery is
discharged or not.
