I have the oem 1300 mAh battery, the HTC 1500mAh battery and a 2600 and 3000 off of E Bay.
Someone had asked to see the pics of them together, here you go...
First, measurements: (thickness)
oem 1300 battery: 4.7mm
HTC 1500: 5.08mm
2600: 9.0mm
3000: 8.7mm
(I would say the 2600 and 3000 are the same... they were .355" and .342" respectively....)
oem battery cover: 8.0mm
2600 and 3000: 14.0mm
Total phone thickness with oem battery cover (used with both 1300 and 1500 batteries...): 12.0mm
with 2600/3000 battery cover: 18.0+mm
Now some pics....
