After it flatline a few weeks ago I replaced the battery again. Then I noticed that it flatlined a couple of days ago. Now tonight I notice once it started to drop from 100% I had a low battery warning ticker tape, never noticed it before but it wasn't there earlier today.
Now down to 90% but it should still be sending data, but it isn't. It has already flatlined.
Is this the supercap or the whole board failing?
Will buy a couple of new batteries to try and keep it going until I either replace the supercap or the board.
Just feel it might be easier to change the board, despite the cost. Any thoughts please.
