Answers:
Batteries for cordless phones, cell phones, and any battery that is used in a portable device only has a certain amount of rechargable capability. They only last up to one to two years. It get's to a point where they can't be recharged. They lose their ability to recharge. It's the structure of the battery. After so many uses they just don't take a charge no matter what steps you take. They are just worn out. Manufactures of these batteries know this and that's how they make their money. If any cell phone is still in warranty take it to your telephone dealer. Cordless phones same thing take it to the manufacturer, but do it speedily. The book is a scam. You can't rejuvenate a battery that's worn out. If you have some doubts call the company that makes the batteries and they will tell you the same thing. Good Luck.
