Introduction: Converting a Digital Foot Scale to Rechargeable Battery.

About: Update 12 September 2017: A very special thanks to Sam Elder, a manager here at Instructables, who tracked down the cause of my lost publications and fixed the issue. Take a bow Sam!

My scale at home uses two lithium button cells. I got fed up spending money on replacing them. I decided that a lithium 9volt rechargeable was the way to go. The 7.2 volts from this battery is close to the 6 volts from the button cells.

Step 1: Solder 9 Volt Battery Clip

Soldering of the 9volt clip into the battery compartment is easy. Just use a multimeter to rule out the series connector.

Fold the leads into the battery compartment and reapply the cover.

Step 2: Use Velcro Strips on the Battery and Scale.

These adhesive strips allow easy removal of the battery for recharging.

Step 3: All Done!

Now the scale has a reusable battery! Cost savings and great for the environment.
