The battery of the HTC desire HD is notoriously lame.

I have bought the following replacements: one identical copy from that originally delivered with the phone (just, new), and others with supposedly higher specs (from what I could gather from reviews, this must be true for some short span of time).

The pages for these models online:

1. http://www.amazon.es/gp/product/B0046BBOAO/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
2. http://www.amazon.es/gp/product/B0056Y8CQY/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
3. http://www.amazon.es/gp/product/B00FFZUK78/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
4. http://www.amazon.es/gp/product/B00JX0UX6O/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

And this is the instruction to replace the battery.
