Did all aluminum macbooks have detachable battery?

Or did they ever make them with the newer built in battery? Also, were the 2.0 and 2.4 ghz models the same release? How big of a difference are the two in processing power? Thanks : )

You can find specs on all Apple products:

• By visiting EveryMac.com
• By using Mactracker (hasn't yet been updated with 2011 models)
• By entering your serial number here to find specs for your model. (Be aware that some models can use more RAM than Apple shows. Check EveryMac or MacTracker to verify.)

Or did they ever make them with the newer built in battery?

No.

Also, were the 2.0 and 2.4 ghz models the same release

Yes.

How big of a difference are the two in processing power?

Negligible.
