Hard Drive Camcorders - battery?

Question

I want to know if there are hard drive camcorders that have long battery life (2-3 hrs or even more / do they even exist?). It's a hassle to carry multiple 1 hr replacement batteries.

I was thinking about getting the JVC Everio GZ-MG360 (or 365).

Answer 1

Not in the box when you buy the camcorder.

You have to buy an optional rechargeable high-capacity battery. They can be expensive.
