Rather than debate the technicalities of battery phyics (which I am not qualified to do). Here is a video of a L-ion battery being damaged. http://www.youtube.com/watch?v=4OsBc8RqSKU

Picked up 2 of these at verizon store. Had a bit of difficulty at first. They went to ring me up and asked for my phone number and said you don't have verizon, I don't think we can sell them to you at sales price. I said yes you can, he asked his big boss man and he said sure! Grabbed them just in time, they only had 3 left

DO NOT GRIND THE BATTERY!
You risk the possibility of serious injury in doing so.
Lithium is very flammable and can explode if leaked while sealed in the device.

I couldn't agree more. No one wants to lose much more than they could ever gain from the battery.
Please disregard any other comments I've made. This includes any useful ones. I tend to make judgements on stuff without fully understanding the details (or trying them) . Battery life is not important.
If you want to develop or modify anything, do so in a proper lab and work under safer conditions

That or just buy an iPhone, iPhone 3G, 3GS, 4, or 4s, or wait for the next one. They are MUCH BETTER, and they have hidden batteries. *sarcasm may be in some or all of this reply*

ohhh, don't be like that.... the advice is GOOD advice, and I agree with the fact that people who aren't comfortable around tools and working on stuff like this really shouldn't be grinding away at battery casings - remember, I just shaved it down with a razor blade, I didn't take an oscillating, vibrating Dremel to the battery which could cause the battery to rupture as displayed in those videos....

I don't know, maybe a quick word of warning is the right thing to do here, no one wants to be responsible for someone coming on XDA and lighting their leg on fire from having a ruptured battery because of something anyone here advised them to do! I know I'm sure not advising anyone to do it! I mean, how many warnings do devs put on stuff here, telling them they are not responsible for a bricked device if they flash ROMs and what not, the same should be said for someone's health if they do this modification, IMHO

I just told them I was picking it up for a friend and had no problem.

The thing is you can probably fit it without messing around with the battery.

Yeah mine fits, a little bulge, but it fits.

About to head to VZ at lunch to pick one up, but their website only shows standard 1850mah for $40? The price for extended is $25 though? Anything special I need to tell them/ask for?
