The Kindle is a wireless reading device, or e-reader, that lets you carry your entire library in a small package that weighs just over 10 ounces. There are more than 350,000 titles available for purchase that can be downloaded to your device in about a minute without the need for external computers or cables. The Kindle's battery life is long, except when the text-to-speech feature is used frequently, in which the device reads the book to you. The battery can be replaced in about five minutes.
Remove the Kindle's back cover by gently pressing down both your thumbs near the cover's center while pushing it to the side.
Gently pry the battery out of the opening with a fingernail. Pull the wiring connector off the battery. Do not dislodge or loosen the white square underneath the Kindle's battery.
Make sure the new battery is the correct replacement by comparing it with the old battery. It should be the same size and have the same wiring connector.
Push the connector on the battery's wiring harness into the Kindle's wiring connector. Gently push the battery into the opening.
Slide the battery cover back into position until it snaps into place.
The Kindle's battery should hold a charge as long as a week with the wireless function turned on, according to Amazon.com. If you turn the wireless function off, the charge should last as long as two weeks.
Make sure you buy the right type of replacement battery for your Kindle. There are three versions of this device: the Kindle, the Kindle 2 and the Kindle DX.
