I bought a Nike sensor a long time ago, with the promise that I would start running/walking more often and be able to track my progress. Turns out I didn't use it and when I finally decide to give it a try the sensor was dead already. :(
Not willing to buy a new one ($20.00) value I decide to search for options.
This instructables offers my take on replacing the battery of the Nike sensor.

Step 1: Disassemble the sensor
Step 2: The Idea
I was wondering whether I was going to put a new battery back and close again or if I wanted to have the means to replace it again in the future. So I decided to do it in a way that I would be able to replace the battery without having to open the sensor again.
After some research I decided to use this battery holder:
Step 3: The Execution
After removing the battery I glued the sensor to the case with electrical tape;
I also remove the battery contacts, leaving only the wires;
I drill a small hole to the top of the case, where the wires will come of the sensor;
Glued the battery holder and solder the batter wires to it;
At this point the sensor was already working but I had to address the wires.
Step 4: Protecting the wires
Same thing here :)
Using some electrical tape I made a "mold" to pour the hot glue. Atter that, let it dry and trim the edges.
