Can somebody tell me witch canon digital cameras have non removal batteries than can charge?

I have to canon digital rebel xti which is a chargeable battery. And its a great camera, you can take very professional looking photo's with it.

To the best of my knowledge no Canon digital cameras have built-in rechargeable batteries.

The TX, G, SD and Digital EOS lines all have removable rechargeable batteries in a "canon" format, meaning they are non-standard batteries. Canon or compatible 3rd party batteries are available if you need extras.

The "A" series generally use rechargeable or Alkaline AA batteries which are a good solution if you use it much for traveling. "AA" batteries are easy to find almost anywhere.
