My Weight Watchers scale WW67T was working fine until it needed the battery replaced. After I replaced the battery it says I weigh 24 lbs. I took the new batteries back to the store thinking I got defective ones, bought another set of batteries, put them in my scale, same thing happened. Decided to buy a new Weight Watchers scale, model # WW54. It worked perfectly. Then I decided to take the battery out of the new scale and put it in the old one to see if it would work seeing as the battery worked for the new scale, but the old scale still showed I weigh 24 lbs. NOW, when I put the battery BACK into the NEW scale, the new scale is behaving like the old one - it gives me the wrong weight. Now it says I weigh 64 lbs. What's going on? Is there a reset button or something? It seems ridiculous that these scales would have such problems just from replacing the battery. HELP.
