I've decided to buy the battery from a local electronics shop. It cost me $4.3, a little more expensive than buying online, but I'd rather not wait three weeks for the battery to arrive in ordinary mail. And that's if they did allow it to be shipped by air. And the peace of mind of
not waiting. Anyhow.
It's gorgeous. A 1500 mAh battery, as wide and thick as the Kindle's original battery and only slightly longer. But it still fits in the Kindle's battery cavity (though not in the black wrapper).
Speaking of the black wrapper, I took the whole shebang (new battery, old battery, and Kindle) to a mobile phone repair shop (since the owner of electronics shop told me that he didn't know how to solder something that delicate). The guy in the mobile phone shop did a freaking amazing job (from the aftermath below, you can feel the sarcastic tone) of gnawing at the stickers and tearing at the foil around the battery, only to be faced by the battery's delicate controller chip, then asking for $7 to continue. Of course I refused after the s**tshow with the battery foil.
After looking at Geekmaster's guide again, I think I'm going to do it myself now. It's only two drops of solder ... but I'm going to make do with superglue until I find somebody to solder it properly.
What do you think? Is it fine? Or is superglue conductive or something? I'm going to wait for your response and any words you have for me before I do anything rash.
You can see the batteries and the (destroyed) foil in the picture below. See how the lamination is all wrinkled, and the plastic and foil are all bent, and I fear that he did something to the battery controller chip. The new battery is the one with the cables protruding, and the old one is the one with the controller on the right.
