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
