Dexcom Users

For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

@ Kati * I have had the issue of shutting down my receiver and the battery being dead when I turned it back on. I was trying to conserve power and it backfired. I have a friend on the Dex who has experienced this same thing twice.

Doug, I got a new starter kit including receiver. My insurance paid for it. Out-of-pocket prices are different from prices shown on insurance claims.

It seemed to need a "paperclip" reset!

onesaint, I switched to a new transmitter after 23 months of use. The old transmitter was not dead at that time but the reach was reduced.

I charged it yesterday for a full three hours and shut it down until this evening when I put my first sensor on. I was unable to turn on the receiver and had to plug it in to turn it on, only to discover the battery was low. On the phone now with customer support, anyone have this problem?

My first sensor is in its 14th month and seems to be doing fine. I have a second and switch from one to the other every now and again.

Can someone point me towards or provide some information about how long their battery lasted in the transmitter?

My 1st year is close to being over and Dexcom is questioning if I want to repurchase the Tx now. I'm curious how long the battery in the Tx will last beyond 1 year.

Comment by Rickst29 on September 13, 2011 at 12:30am
Kati *, the battery assembly includes a "smart" charge control circuit. If you leave the Dexcom plugged into the charger all night, the charger itself will continue to put out 5 volts all night long- but after the battery has reached "full charge", the charge control circuit does an electronic disconnect.

You CAN'T hurt it.

I charge my every night on my bedside table while I sleep. I don't seem to have a problem with overcharging.
Comment by Andrew Tumsuden on September 12, 2011 at 9:01pm
dont worry about overcharging it... though yea 3 hours ive noticed usually fully charges it and the more the screen is lit up the faster the battery burns
