I really don't think that is true. I did find an Apple document that only said that the processor speed would be throttled with the battery removed, but it did not specify by how much, and certainly said nothing about disabling a core. I did see some performance results run with and without the battery and if I recall correctly, the difference was 15-20%. The reason Apple did this was because with the battery removed there is a risk of the computer drawing more than what the charger is capable of supplying, and thus shutting down.
if i have time i will try to dig up a machine with a removable battery and post some screen shots. IIRC attempting to max the processor via the terminal resulted in only a 100% load registering in activity monitor, not 200% as would be expected in a dual core system.
'Macified', I'm on again this morning, and I'm telling you, it's browsing much quicker again than before (WITH the battery installed). Nuts. I think I'll wait until I hear from 'Paddy' to see if these $47 batteries are the real deal before ordering one. I mean, my MB is almost 4.5 years old. Probably going to need to plan to get a new one in the summer anyway.
Well, I've bought 3 batteries from battdepot.ca (one for a G4 PB 800 GHz, one for a G4 1.5GHz and one for my MacBook Pro 2.33GHz) as well as a replacement adapter for the older G4, and all have been flawless and are still working now. (old G4 battery purchased in Feb. 2009 along with the adapter, and the other two batteries were purchased in Oct. 2009)
Two years out, the MBP battery has a full charge capacity of 4822 mAh after 158 cycles. So, it's dropped somewhat in capacity from 5800 mAh, but that's not unexpected given that it's over two years old etc. Actually, given that most Lithium Ion batteries only last 2-3 years, it's doing well. Of course, this laptop hasn't been charged as often as it would have been if it was my principal Mac, which it's not.
Thanks for all the expertise. I don't know anything about dual core or mAh. But I'm still humming along today with SOME evidence of a zippier browsing experience. Never suggested it was suddenly lightning-fast. I think my 595 cycles likely suggests a tired old machine. 'Paddy''s account of things is pretty compelling. I suppose I could save about $100 now, and make good use of that later in the summer when I'll probably have to upgrade to a MBP.
Dove into the deep end with Paddy. Ordered the $47 battery. Silly as it is, the MB is still zipping along smashingly today without a battery. Go figure.
I'll come back with an update once the battery arrives and I've installed it successfully. Thanks for all the advice and tech expertise. It's what makes this forum my go-to place for anything Mac-related.

'tdu', it's on the first page of the thread. 'Paddy' left a link. Called BattDepot, Canadian. My model for the battery is A1185, just ordered the replacement for that; $67.79, shipping, taxes. Worth a shot.

I have read some horror stories about cheaper batteries, so I am leery. There are a few sites recommended in other forums I use that sell batteries that are supposedly high quality, and slightly cheaper than Apple's. $67 seems too good to be true lol. Makes me nervous.
Read 'Paddy's' post? I'm thinking he's had success with them. For me, it's low risk, I guess. Probably need to upgrade to a MBP in the summer. As I said, I'm 4.5 years in with this one. Hell, I haven't seen the need for one, the past 3 days!

He??? Um...nope. Try "she." And it's my real name - so no need to put it in quotes.
