Seidio Innocell 2600mAh Extended Battery for T-Mobile G1

With 125% more power than that standard battery that comes with your T-Mobile G1, this extended battery from Seidio, will keep you powered up all day.

Even though this battery offers a lot more power, the battery will only extend your T-Mobile G1 by 5 mm and your hand will rest comfortably on the battery door which is included.

The door is made from a hard plastic with a smooth rubberized finish, so you will have a better grip of your phone. The door also has cutouts for the camera and speaker which will give a better overall sound quality than the original battery door.
