[Q] Best Extended Battery without adding bulk to the phone ?

[backlashsid]

as the title says....
any good extended battery (dont want 2600 mAh which adds bulk to the device) !!
around 1400-1500 mAh should do.

There's a comment on ukrainian web site in which a guy says he uses 1830mAh battery for HD2.

Someone please c\d if this is possible.

also, does someone know if there is battery compatibility between HTC devices and any battery compatible with HD7 in particular?
