So I discovered with my CTEK battery BT monitor that the Lithium US charger was not charging at 13.8v initially nor maximizing at final step. Garage temp at 58-60 degrees. It stayed at 13.6 for hours, and eventually went to float.
If it was a temperature thing and in the manual as such I would not have taken the step to get a new one.
…. and it went to 13.8v in step 2-3 as it should.
Anyone else notice reliability issue with CTEK?
