This slim extended battery will provide approximately 33% increased power than the battery that initially ships with the Treo 750 or Treo 680 (1600mAh versus 1200mAh).This Treo battery will give you longer usability and is great for people on the go without access to an external charging alternative.
This battery is compatible with the original OEM door, so no extra bulk or thickness will be added to your Treo 750 or Treo 680.
