Jason,
If you are looking for camera and or laptop batteries, give these guys a try.

I have had a couple of dealings with them and purchased laptop and camera batteries as well as a battery grip for my 60D. No issues with quality or service, and I couldn't beat their pricing anywhere. They also offer free postage for 2 or more items, and there here Melbourne.
Not affiliated, just a happy customer.
