is this normal for nc200

I have four (4) of these batteries to get 24v and after about 18 months my battery monitor shows the attached graph after a day of use ( barely any use ). This cannot be normal, is it?

Given the little use and SoC at 100% then it looks reasonable.
You may have expected the battery voltage to go to 27.2V (battery spec Float voltage setting).
What Float voltage do you have set on your charge controller?
