Will A CS1-Series PLC's Program Be Lost If Its Backup Battery Is Not Replaced After Its 5-Year Service Life Has Expired?

Modified on Sun, 11 May, 2025 at 10:12 PM

The program will not be lost as long as the PLC's power supply does not go OFF.

The battery service life is 5 years, so replace the battery every 5 years to prevent problems such as electrolyte leakage.
