Hello, We now have a customer with similar issue as above, after one month, the battery on the core has dropped from 3v to 2.7v, which leads the RTC to drift, and consequently the OPC -UA connection with HMI to drop. Has there been any solution/ workaround found for this issue yet? MNR: R911411150 FD: 21W39 SN: 7261403760292 Also worth mentioning, does this core have the old or modified battery holder? Thanks
