Yeah - the group in question does both G4 and G5 battery replacements. Looks very solid. ---

Very interesting… When we were on the G4 we did not get warnings. Been awhile though (as we have been G5 for a bit now). That was something I did not like with the G4. The fact that it was a “surprise” when it stopped working. ---

The G4 gives vague low battery warnings, which are actually based on battery level (vs the time-based ones on the G5). That said, I would just ignore it and keep using it until it flat out stopped working, which would be a while after the warning. ---

> [@cardamom](#): > > That said, I would just ignore it and keep using it until it flat out stopped working, which would be a while after the warning. My previous two transmitters have always died within a week of getting the warning. So for me it’s been pretty accurate. ---

I pulled it out tonight after four restarts failed to get it to work. Sure enough, dried blood around the sensor. I have a new one in, so here’s hoping it works this time around. ---

> [@Eric](#): > > Try this - before you look at your CGM or test your BG, just take a guess. I’ve been doing this quite a bit, since I read a much earlier post where you suggested it. At random times, or before I test, I hear this voice (your voice?!) saying, “Think about it and guess first.” I’m astonished how close I often am, though 70 to 110 feels pretty much the same. I don’t think I’m _dependent_ on the CGM so much as finding it difficult to tune out the noise (something I’m usually good at in life) – or ignore the judgmentalism that arises from that data. Maybe I should cover the screen with duct tape.🤨 [Previous page](https://forum.fudiabetes.org/t/new-sensor/2774.md?page=1)
