How often should I change the battery in my scale. This thing gives me some crazy numbers. Up 2 down 3. Up 5 all in the same day. Yes I'm following the rules, no its not that TOM. Even my kids are gaining excessive pounds in one day. Am I going crazy or do I need batteries?

Are you moving it on the floor? If you're on an uneven floor, I find that gives very random readings. I'd think the batter should work or it shouldn't, not give a crazy reading... maybe you need a new scale!

Mine does that too, so I keep stepping on til I get 3 consecutive readings in a row. I bought mine at walmart and it was a cheap one-probably why! I also changed the battery after about a year and it still does it. I'm looking at buying a drs scale-about 150~ but at least you can depend on it.

find 1 scale only that is reliable like at the gym or at your doctor and use that one only. . .throw away that scale of yours, doesn't seem to be reliable at all. . . and most important, don't become a slave of the scale! Good luck

Thanks everyone. I need to leave the scale alone

for awhile. A break from it will be nice. I think this one will go to goodwill. And I will wait until my 6 month check up with my surgeon before I weigh again.
