Good news everyone :)
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
The way I did was using a X-acto knife to open the sensor, be careful not to cut yourself, this is a task that takes time and patience. Since I didnt take pictures during this part of the process I am using someone's else pictures.
Step 2: The Idea
Ok, since I already got the sensor open, it is time to present my 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
Let's go to whats matter :)
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
If there is one thing I really like is how awesome hot glue is. I have been doing a lot of projects that I used hot glue to protect 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.
Step 5: Final Produtc
Ok, I still need to buy some shrink tube, to cover everything but the battery but it's ok at this point :)
Thank you for looking.
