Our Dexcom G5 Transmitter is a transmitter that is like new that has been refurbished with new batteries. The batteries installed into this transmitter have been replaced with a fresh set of Renata 389 batteries (the same brand of batteries used by Dexcom in the G5 transmitter). Our battery replacement service comes with a 90 day limited warranty (similar to the warranty you receive when purchasing a brand new transmitter). The transmitter will work like a new one with 3rd party apps, a Dexcom Receiver, and Pumps that are compatible with the Dexcom G5 transmitter. The transmitter begins using the batteries and the time starts on the transmitter at the time of refurbishment so it is best to use the transmitter shortly after receiving.
To have a complete Dexcom system, you will need a Transmitter, Sensors and a Receiver (or compatible smartphone that can run the apps).
Notice: Dexcom has announced that they have discontinued the Official Dexcom G5 Mobile App. We recommend using "xDrip4IOS" for Apple Devices (https://xdrip4ios.readthedocs.io) or "xDrip+" for Android Devices (https://github.com/NightscoutFoundation/xDrip). Please keep in mind that these apps will not notify you when it is coming up on 3 months and the transmitter battery could die without notice.
