I purchased the Anker Upgrade 2 x 2700mAh Li-ion Batteries for Samsung Galaxy Note Batteries for AT&T Samsung Galaxy Note Samsung SGH-I717, with two replacement batteries.

The batteries charged in an hour and lasted all day in my phone. I now have 2 extra batteries which are easy to carry and provide continuous power for the Galaxy Note. The charger is easy to use with built-in wall plug or computer USB cord.

Cost was reasonable. I am very happy with this product.
