How to replace the battery for Sony Reader PRS-505

How to replace the battery for Sony reader PRS-505. The battery should cost you around $15-25. You will need a small cross screwdriver you can get it on eBay for 2-3 dollars (also a screwdriver in eyeglass repair tool kit should be fine), or purchase a battery with tools included. You will need also double sided adhesive tape to use with the extenders and the battery. Good Luck! Let me know in comments if have any questions.
