How to replace S7-400CPU battery
Thread Content
We have a set of S7-400CPU batteries that are broken, and now we want to replace them. I don’t know what issues we need to pay attention to during the replacement process. Please give me some suggestions from colleagues who have had similar experiences. Thank you!
Is it just that the CPU battery is dead? (The shape is the same size as a 5# battery, but it is 3.8V). If you are powering on, don't pay any attention, just take out the battery and replace it with a new one!
If the CPU is redundant, then there is no problem. If not, be careful and be mentally prepared.
CPU out of power? ? The PS40X in front is out of battery! This can be replaced directly while the power is on. But when there is no external power supply, remove it, and after restarting, the CPU will perform self-test again. This may take more than half an hour. There is no guarantee that the programs and data stored inside will be lost. But if the CPU is redundant, there is no need to worry. it will sync automatically
It's a small battery, just turn it off and replace it! This thing is not rechargeable and always needs to be replaced!
It can be replaced directly when it is powered on, be brave: lol
They are all directly replaced, and it doesn't matter as long as the power module supplies power normally. The battery is 3.6V and should be replaced every 2 years.
It’s not just two years! In the past few months, we have been reporting low battery! Much better after replacing it! Personally, I feel it has no practical significance!
