Dexcom rebatterying

As said in the previous post, after Simon sent me a transmitter (much appreciated) that didn’t work, I decided to try my hand at re-batterying my own.

All I used was a file, a small screwdriver, a razor blade and a hand drill. I went to Bunnings to get the batteries (which they have online) but they didn’t stock them. So I tried shopping centres and chemists, one of which had a very similar battery for $1.30. Defeated, I went to Mister Minit which I knew would be pricey but I didn’t expect to be $36 pricey!

I had Simon’s as a guide. Here is a comparison.

Simon’s is on the right with the nice epoxy

Getting to the batteries

The “feet” of the transmitter fit nicely into a groove in this block of wood.

Ready to go

After ages of filing, I finally struck silver.

Those are the old ones. Not the new ones.
That’s how much I had to file off

Except for epoxy

I did the voltage check which was fine. Finally I tried it out and... you guessed it, it didn’t work.

After all that 🙁
