They're protected. Look close, and you can see the protection circuit in the pic. Note also that the seller is "china_seller200907", located in Hong Kong. 1 week means either they have a US warehouse, or more likely that they will *leave Hong Kong* within a week. Then there's 7-15 days to cross the Pacific, possible lag time in customs, and however long it takes USPS to get it from San Francisco or San Diego to you.
Be prepared for a wait, but if they actually DO show up in a week, let me know![]()
10 days total from ordering to getting them. Not too bad! I ordered a charger too - the charger came 2 days earlier than the batteries.
