October 2013:
After a few months of use I had to change the battery, and then surprises: once the new battery inserted my balance shows me that her condition is low (while it was still in its original packaging, ok date). After 3-4 tedious uses (the load is so low that the screen is barely visible and off) I had to bring myself to buy a new one !!!
I tested my balance with the new battery purchased from Amazon and not worry Duracell - 75072668 -2 Special Electronic Devices Batteries - 2032 Grand Blister).
