Dexcom G4 Cover

Snap on battery cover for Dexcom G4 slim. This thing allows for battery changes on the Dexcom G4 slim transmitter. NB. ** This is version 1, let me know if you think it can be improved. ** You'll need DIY skills to cut down (or mill flat) the G4 transmitter leaving 3.9 mm from the flat base. Then remove old batteries, as per the YouTube video. (Do a search) Clean the contacts well. I use a small rotating wire brush in a hand held hobby grinder. I've found there's no need for solder if you spring out the bottom contacts and form the top ones into a curve so that they will be pressed down to contact by the cover. Put in 2 new SR1120W batteries Clip on the cover & seal with silicon rubber. Test the voltage across the 2 contacts as per the Youtube video Add a bead of silicon to make it waterproof if required, this would need cutting with a blade before the next change. Subsequent battery changes will just be a matter of unclipping, changing the batteries and clipping the cover back in.
