Ditto, condolences on your loss but I do appreciate the useful information. The sprint 2600 mAh battery is good but I still need moar power!

MUGEN 4500 MAH Battery Info for EVO
Source Link: http://www.mugen-power-batteries.com
Just get the one for the Touch Pro 2 because it is the same Battery spec (Thank you HTC for keeping good specs across phone models).
I recommend getting directly from Mugen because you never know what happens on eBay. I got some bunk Seidio 3500s from there.

Update
I'm running CM7 with Savaged-Zen 1.2 CFS kernel. I get significantly more usage than the 3500mAH Seidio.
i installed nets kernel, set ondemand on setcpu.. fully charged it night before last, has been off charger all day yesterday, all night, and titanium backup came on to do the backup routine last night so the screen was on all night, and i have it says: 56% 26hrs left.
