Introduction: Converting a Digital Foot Scale to Rechargeable Battery.
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.
We have a be nice policy.
Please be positive and constructive.
