How do I know when my Dexcom G4 receiver should be replaced? I have been using it since the start of January 2015, nearly 15 months so it is well over warranty. I recently replaced my 1st transmitter after 13 months. I am self financing my Dexcom system so the longer things last the better!
I don’t think there is a hard and fast rule. I would use until the battery no longer holds a charge.
I’ve had one last 2, 2-1/2 years without a problem other than needing to be charged a bit more frequently.
