TXT batterycell voltage

[hvn]

Hi,

My TXT controllers didn't retain the date & time anymore (setting it back to 2000-1-1 and time counting since boot), so I checked their battery cells. One was still 3V, so I suspect that this controller has a problem. However, the battery cell of the other controller has 2,36V which leads to the question what the critical battery cell voltage is for the controller to retain date & time. Does anyone know?

Thanks

Try it with a new battery anyway.
Might be that the cell is broken and only as 3V at 0A.
