how big of a battery can you get before you have to get a different back on the phone?

The Seidio 1750 is the largest, but there have been speculations that it is only 1500, so you could always get an HTC 1500 battery off of ebay for less than $41 (price of the Seidio I got) and get the same effect.

I purchased a Seidio 1750 mAh in June from Amazon, about $45. I am very pleased with it. I work in a hospital, 12 hour shifts. The original battery would be depleted halfway through my work day. Then I was trying to find places to plug it in. It took about 4 full charges on the Seidio battery until it lasted my whole shift. The Wi-Fi and the bluetooth are the only apps I turn off (I leave the GPS on all the time). I get great internet with the 3G even running my Slingbox. I would highly recommend changing batteries.
