One of the most frequently asked questions about the Nike+iPod Sport Kit is “How do I replace the battery in the shoe sensor?” The Instructables website answers that question with a handy DIY guide. With a few simple tools, a four dollar CR2032 battery, some tape, glue, and a passion for tearing things apart, anyone can get their Sport Kit up and, um, running as good as new.
I haven’t tried this myself, but if the photo below looks like a good time to you, I encourage you to give it a shot and let me know how it works. If you completely destroy your sensor, you can always get a replacement from Apple for $19.
Thanks to reader Andy for the tip.
