Kudos! I don’t know if you read the very long G4/G5 battery replacement thread: > [@Dexcom G4/G5 transmitter battery replacement](https://forum.fudiabetes.org/t/dexcom-g4-g5-transmitter-battery-replacement/910): > > When traveling I was forced to check a bag and neglected to take out my Dex (transmitter too). It froze (was over a year old), now the receiver does not pick up the transmitter, and I cannot currently allow myself (financially) to purchase a replacement; so I found a FB group where you can have it ground down and have the battery replaced by someone experienced! I am goi g to attempt it because I want my CGM back! Any experience with manual battery replacement or using such a service appreciated… --- _[View the full topic](https://forum.fudiabetes.org/t/anyone-ever-try-a-rechargeable-battery-in-the-g5-transmitter/3430)._
