A few months back I purchased a cheap kitchen scale that I figured would come in hand for projects in both the kitchen and the workshop. As time would show, the scale was quite useful but with one major flaw. Being a scale of the cheaper sort, it chewed through expensive button batteries and would inevitably fail to be working just when I needed it most. This weekend I decided to fix an otherwise fine scale by upgrading the battery. While most people wouldn’t realize it, we actually all have a variety of high quality, rechargeable batteries sitting idle in the back of draws and closets. Those old cell phones and otherwise obsolete electronics can still prove useful. Take a look at the photos below which are in order and let me know if you have any questions. The new battery will last about 3x longer and is easily rechargeable.

Take a look at the photos below (click to zoom) which are in order and taken throughout the project, and let me know if you have any questions. The new battery will last about 3x longer and is easily rechargeable (via the original phone as a charging dock).

Do you have any devices that need a battery upgrade? Tell us about it in the comments and check out my other Daily Dose articles.
