Respectable extended battery (prodicell? chichitech?) with stock battery door?

[DerangedGoose]

Is there an extended battery out there that works well and doesnt require a bigger door?

Theres a ProdiCell 1800 mah one here, but some reviewers are saying capacity drops after a week or two?

Amazon.com: ProdiCell Premium 1800mAH Slim Extended Battery for LG G2X, LG Optimus 2X and LG Star: Cell Phones & Accessories


ChiChiTech sells 1700 mah ones that have gotten better reviews, also with some duds:

And does anyone have any experience with this 1980 mah one?

There's one on eBay that's 3500Mah! Which is amazing but yes it has a bigger back. I think its worth it and might buy one!
