Hello @Aod15 
Hope you are doing well, 
Its best to have both the controllers up and running for redudancy and performance purpose. 
Incase the other(working) controller fails, it might led to potential outage, 
I would advice you to replace the same at the earliest. 

@Aod15   I hope this helps!

Hi @Aod15 

The purpose of the coin battery is to provide backup power for the real-time clock. This error has no impact on data.

If both controllers are operational and the only error is the coin battery, there should be no issues using it as it is. You may continue using these controllers.

In the event of a power failure, the date and time will reset and you will have to manually set the date/time again.

Here are the instructions to replace the controller if you choose to in the future :
