Unfortunately that means that your transmitter is close to death. When both voltages drop below 300, the system will give you the dreaded message of transmitter death. As you can see in this thread, if you use a good fresh transmitter that hasn’t been stored too long, you can get an impressive 130 or ore days from them. > [@How Long Does a G5 Transmitter REALLY Last? \*\*UPDATE-Transmitter Died\*\* UPDATE-New Transmitter \*\*\*UPDATE-2nd Transmitter sob](https://forum.fudiabetes.org/t/how-long-does-a-g5-transmitter-really-last-update-transmitter-died-update-new-transmitter-update-2nd-transmitter/1307): > > The Dexcom G5 transmitter will shut off after 105 days via a software command from the receiver. But that doesn’t mean the battery is dead or that the transmitter ceases functioning. It just means that the G5 receiver will no longer accept readings from it. So just how long will the transmitter battery last? Mine is at 123 days and still pretty strong. I’ll keep updating each week until it dies. Note that voltages and resistance are still in the excellent range after 123 days. BTW, thi… --- _[View the full topic](https://forum.fudiabetes.org/t/signal-failure/10150)._
