My relatives have a similar type of bathroom scale.
When the button cell ran out, I popped in another one we had lying around.
One month later, the button cell was dead, after using the scale a handful of times. Obviously something was draining the button cell battery when the scale wasn't in use.
I could try and debug the scale, but given that even ten minutes of investigation would be more than the amount of time I spent using the scale in one year, I just decided to remove the button cell when the scale wasn't being used.
Two years later, that button cell still works in the scale...
