I've figured out how to take care of non-functinoal batteries. After going through the phone tree from the number printed on the battery, I got to a helpful tech who was aware of the Woot sale, and knew that some of the batteries were arriving nonfunctional. I told him that I'd tried every permutation of charger, battery, and wristwatch, and that one specific battery wasn't operating. He told me to do the following:
1. Print out the purchase confirmation email from Woot for the watches.
2. Write on the email or on a seperate sheet your full name, telephone number, model number, and a description of the problem.
3. Fax it all in to 212.448.7682
4. Wait, then get a replacement battery in the mail.
Shouldn't be a problem, just an inconvenience. I'm going to include the confirmation page from my Woot profile, the model number of the wristwatch communicator, AND the battery modle number just in case. So I've got one battery doing the initial 12 hour charge thing, and another that should be in the mail soon.
Edit: I don't know if they call you back to verify then get the shipping address, but I'm going to include that in the documentation I fax in as well.<br/><br/>
