A: This scale takes 4 AAAA batteries (no totally common, but available all over the place). There is a plastic door on the bottom of the scale that you remove to change the batteries. Not sure who Brian R is but I assume he works for some other scale company. I have had a Greater Goods WIFI scale for over 4 years and it is awesome and has been very accurate, consistent, and stayed connected to my WIFI almost without exception. If Brian R can't even figure out how to change 4AAAA batteries, he probably should probably use a rock and teeter/totter to weight himself. Of course the batteries are replaceable!
A: It's probably a disposable scale considering how this company does business. Sorry, but you are SOL along with the rest of us. Don't expect any support either.
