Another faulty TB48

View attachment 9965 Just checking through my batteries this afternoon before a couple of jobs this week and one of the newer ones about 4 months old is showing as 'battery cell broken'
I ran it down to 5% and recharged and this is what is now showing. Cell 3 is obviously down but the app is still showing the full 5700mAH.
Presumably not safe to use?
Any thoughts?
