The Seidio extended battery for the HTC TyTN II or Tilt will give you longer device usability and talk time, which is great for people on the go without access to an external charging alternative.

This battery will give you 10 to 15% more power than the original battery that is shipped with the HTC TyTN II or Tilt and this battery is compatible with the original OEM door.

The battery will not add any extra bulk or thickness to your phone, just added power!
